What does the constellation Leo look like?

Leo is an ancient constellation that is both large and visually stunning. It has long captivated the interest of space enthusiasts around the world. Detailed information about Leo can be found below.

The earliest record

There are various accounts regarding the origin of the Leo constellation. One of the most popular versions comes from ancient Greek mythology, which recounts the tale of Heracles defeating the Nemean Lion and offering it as a sacrifice to his father, Zeus. It is said that Zeus wanted to commemorate his son’s heroic feat by immortalizing it in the form of a constellation.

Ancient Egyptian myths include references to the constellation. During this era, individuals held the belief that celestial bodies were closely linked to natural events. According to their understanding, when the stars within a specific constellation shone brightly, it indicated the presence of a heat wave. This was also the time when the desert became the domain of the king of beasts. As a result, the constellation was named accordingly.

Astrologers from ancient Sumeria and Mesopotamia were also aware of this celestial body. However, the first referred to it as the Ill Dog.

Mesopotamian astronomers, on the other hand, identified it as the Lion. The constellation could not be overlooked by Babylonian priests, who referred to it as the Great Lion.

As a result, there is no definitive data on the exact discovery of this constellation, but references to it can be found in various sources.

Leo is a group of stars that the paths of the ecliptic and the celestial equator pass through. It can be found positioned between the constellations of Virgo and Cancer. In close proximity are also the well-known Big Dipper and various other celestial entities.

Leo is a constellation that is known for its bright stars and is ranked 12th in magnitude. It is easily recognizable in the sky due to its distinct shape. Additionally, by locating Leo, you can also spot other constellations.

Leo is classified as a “spring” constellation, as its stars shine the brightest during this season. However, it can still be observed in the sky during the winter, summer, and fall months.

Geographical Position

The Leo constellation can be observed from any part of Russia. It is situated in the northern hemisphere. Virgo is positioned on one side of Leo, while Cancer is located on the other side. This constellation lies along the ecliptic, which is the path of the Sun, and is a part of the zodiac circle.

Moreover, Leo is adjacent to neighboring constellations like Ursa Major, Sextans, Crater, Leo Minor, as well as Coma Berenices, Hydra, and Lynx.

The constellation can be observed in various ways. One method is by utilizing the moon. To accomplish this, one must determine when the moon will align with the Lion, the natural satellite of the Earth serving as an accurate indicator of its position.

Another way to locate the Lion is by referencing the Big Dipper, which is situated to the north of this constellation. If one visualizes the pouring of water from the Dipper’s bucket, it will coincide with the position of the Lion.

Identification of the constellation can also be accomplished by locating its brightest star, Regulus. Adjacent to Regulus are several other luminous stars that collectively form a trapezoid shape.

The primary entities

The star constellation known as Leo contains more than 120 celestial bodies. However, only the six most luminous stars form its “head”:

• Regulus. This star is the brightest in Leo and the 22nd brightest in the entire night sky. It is located a mere 78 light years away from Earth. Many individuals mistakenly believe that Regulus emits its radiance alone. In reality, it is composed of two pairs of stars. Therefore, Regulus consists of four individual stars. The first pair contains a blue-colored object known as Regulus A. The second pair consists of a white dwarf, which is often difficult to observe due to its frequent overlap with the Moon, Mercury, and Venus. This second pair is made up of an orange and red dwarf.
• Denebola is the third brightest star in the constellation. It is situated approximately 36 light years away from Earth. In addition, it is the second brightest star in the constellation and the 61st brightest star in the sky. Denebola emits a luminosity that is 12 times greater than that of the Sun, and it has a mass that is 1.8 times the mass of the Sun. The star exhibits a constant twinkling effect and undergoes changes in its color every 2-3 hours. This phenomenon is attributed to Denebola being a hot white giant star. Its layers move in and out, which causes the flickering effect.

• Algieba. It is situated at a distance of 120 light years from our planet. This celestial body is also made up of a binary star system. Algieba A, one of the stars, is an orange giant that emits light 180 times brighter than the Sun. The other member of the pair is a yellow giant, shining 50 times brighter than the Sun.
• Algenubi. It is the fifth most luminous star in the constellation.
• Zosma tlt. Astronomers predict that in 600 million years, this star will transform into a red giant. Currently, it shines 15 times brighter than the Sun.
• Hort. With a mass 2.5 times that of the Sun, this star is visible to the naked eye.

Asterisms

Asterisms are groups of stars that make up constellations.

They have a sickle-like appearance, which includes entire galaxies, namely:

• M65 (Monsieur 65). Charles Messier discovered this galaxy in 1780. It is characterized by a lack of substantial dust and gas, resulting in relatively low levels of star formation.
• M66 (Monsieur 66). Charles Messier also discovered this galaxy in 1780.
• NGC 3628. William Herschel discovered this galaxy in 1784.

These galaxies belong to the spiral type and are located 35 million light years away from us.

Distinctive Characteristics

Curiously, Arab astronomers bestowed the title Kalb Al-Asad upon the primary luminary in the constellation. This designation signifies the essence of the Lion. Conversely, Europeans named it Regulus, which can be interpreted as Prince.

The second brightest star in the constellation is known as Danab Al-Asad, which translates to the Tail of the Lion.

Here are some other interesting facts about the constellation:

• Within the constellation lies Wolf 359, the fifth most distant star from the Sun. Discovered in 1918 through astrophotography, this star is not visible to the naked eye but can be observed with specialized equipment.
• The constellation is also the location of the Leonids meteor stream, which is also referred to as a meteor shower. The last occurrence of this phenomenon was in 1998, and scientists predict it will happen again in 2031. The first recorded mention of this meteor shower was in 901.

During the month of May, the sunset occurs later, allowing for several hours of observation of this remarkable constellation in the southwest.

"Leo" is made up of a variety of different stars: some bright, some dim, some dwarfs, some giants, and so on. Apart from Regulus and Denebola, there are other stars present in the constellation of Leo. One notable star is Algieba, a double star located at the base of the head that symbolizes the predator’s mane. Another interesting object in Leo is R Leo, which is a variable star with a long period.

Among the closest stars is Wolf 359, a red dwarf that shines 100,000 times fainter than the Sun. The distance to this faint star is estimated to be 7.80 light-years. DP Leo is also worth mentioning as it is a double star, with a white dwarf accompanying the red dwarf. In addition, this system contains a gas giant exoplanet among its minor objects.

The dazzling star Regulus or α Leo (Alpha Leo) in the constellation

It is acknowledged as the most brilliant in this constellation. The temperature on its surface soars to a staggering 10,000 degrees Celsius. It boasts a rotational velocity of 300 kilometers per second. Its age is estimated at around 50 million years. Regulus is part of a triple star system, as it attracts two satellites. The luminary was christened by Copernicus. It is referenced in computer games, television series, and feature films centered around space exploration.

Denebola: a Hot Star in the Leo Constellation

Denebola, also known as β Leo (Beta Leo), is the third most luminous star in the Leo constellation, following Regulus and Algieba. It is situated in the “tail” region and is located at a distance of 11 pc from the sun. The name, derived from Arabic, perfectly signifies its position in the constellation. With a surface temperature of 8,500 Kelvin, Denebola is a hot white dwarf star estimated to be around 100 to 380 million years old. Its luminosity is variable, undergoing active pulsation phases that cause a 0.25 m change in luminosity.

Double star Algieba or γ Leo (Gamma Leo)

Algieba is categorized as a binary star system. The mass of each star is estimated to be twice that of the sun. The primary star is identified as a yellow dwarf with a spectral classification of KO III. It has a surface temperature of 4470 Kelvin.

French astronomer Pierre Mechene discovered it in 1780. The star cluster spans an impressive area of 95,000 light-years. Contemporary researchers have proposed the existence of four supernovae in the galaxy, namely SN 1973R, SN 1989B, SN 1997bs, and SN 2009hd. Additionally, several enigmatic cosmic objects emitting powerful X-rays have been detected, including one situated in the star cluster’s core.

Galaxy NGC 3628

The appearance of this spiral galaxy is similar to that of the Milky Way and it is located near M65 and M66. In the world of astronomers, it is often referred to as the Hamburger. When viewed from the side, a dark area can be clearly observed, stretching from one edge to the other. NGC 3628 is also a part of the Leo Triplet and is the least bright of the three. It spans an area of 100 thousand light years and is situated 35 light years away from the solar system. The most recent study of this galaxy has revealed the presence of a massive black hole in its central region.

“Perspective” galaxy NGC 2903

William Herschel discovered NGC 2903 in 1784. Based on observations, this star cluster is slightly smaller than the Milky Way and is located 8.9 parsecs away from our solar system. Notably, NGC 2903 has a high rate of new star formation in its central region. This hypothesis is supported by photographs taken by the Hubble telescope, which show young star clusters surrounded by ionized hydrogen clouds. The galaxy is also believed to have a powerful X-ray source of radiation.

Leo Constellation: Ancient Mythology

The mythology surrounding the Leo constellation traces back to the heroic tales of Hercules. According to ancient legends, Hercules, the son of Zeus and Alcmene, bravely defeated the Nemean Lion, using his incredible strength to strangle the mighty beast. In recognition of this extraordinary feat, the lion was immortalized as a constellation by Zeus himself.

In the aftermath of Hercules’ victory, the city of Nemea celebrated with grand games and a period of peace was declared. As a tribute to his son, the god of thunder transformed the lion into a constellation, forever visible in the night sky, ensuring that future generations would never forget the remarkable deeds of Heracles.

Mythology behind Leo constellation

The tale of the constellation of the ruler of the celestial kingdom revolves around the Nemean lion and Hercules. While he may no longer hold the title of king of the jungle here on Earth, he proudly proclaims himself as the king of the night sky in the galaxy.

The history of this constellation is intertwined with the ceremonial tribute that Zeus, the father of Heracles, wished to bestow upon him after his triumph over the Nemean Lion. The tribute involved placing him in the heavens so that the bravery of his son would be forever remembered.

The Nemean Lion

This creature inspired fear in all who encountered it, leaving a trail of terror in its wake. And its fearsome reputation was well-deserved, as it was the offspring of the god Typhoon, the creator of powerful hurricane winds.

Challengers from all corners attempted to defeat the Nemean Lion, but none succeeded. This is why it became the central focus of the twelve labors assigned to the mighty Hercules.

According to legend, Hera, the wife of Zeus, was angered by his affair with a mortal woman, which resulted in the birth of Heracles. This ongoing conflict brought constant suffering to Hercules, leading him to unleash his fury on Hera, her children, and even some of his own relatives who happened to be present.

However, his sibling managed to locate him and convinced him to seek wise advice from the Delphic oracle. The oracle instructed him to undertake twelve tasks that would help him ease his troubles and guilt.

Embrace the challenge

Without hesitation, young Heracles embraced the challenge, eager to make amends for his transgressions as quickly as possible. The initial task involved putting an end to the relentless pursuit of the Nemean lion, a formidable adversary with an impressive history of triumphs.

To effectively accomplish this task, Heracles devised a brilliant plan to block one of the cave’s entrances where the lion resided. This forced the creature to exit through a vulnerable door, allowing Hercules to seize it by the neck and suffocate it.

After the animal’s life came to an end, he made preparations to remove its skin, and in order to accomplish this challenging task, he heeded the guidance of the goddess Athena. The animal’s skin was utilized to create a suit of armor, complete with a protector featuring the likeness of the Lion’s head.

In this manner, he proceeded to complete the remaining 11 tasks, thereby alleviating himself of the remorse and guilt brought on by his transgression. As a result of his bravery, Zeus bestowed upon him a reward by transforming him into the constellation of Leo, where he would reside in the heavens.

It occupies the second quadrant of the northern hemisphere (NQ2) and can be observed at latitudes ranging from +90° to -65°. Leo is bordered by the constellations Cancer, Veronica’s Hair, the Cup, the Lesser Lion, the Sextant, Virgo, the Lynx, and the Big Dipper.

Leo is home to 5 Messier objects, including Messier 65 (M65, NGC 3623), Messier 66 (M66, NGC 3627), Messier 95 (M95, NGC 3351), Messier 96 (M96, NGC 3368), and Messier 105 (M105, NGC 3379). Additionally, it hosts 11 stars that have planets in orbit.

The brightest star in Leo is Regulus, boasting an apparent magnitude that can reach as high as 1.35. This constellation is also associated with two meteor streams. The Leonids meteor shower peaks on November 17-18 and is particularly radiant near the star Algieba. On the other hand, the January Leonids are a smaller stream that reaches its peak on January 1-7.

Leo is a member of the cluster of celestial patterns known as zodiacal constellations, which consists of 12 signs including Aries, Taurus, Gemini, Cancer, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. Take a closer look at the star chart to observe the arrangement of stars in the Leo constellation.

Legend

Leo is considered to be one of the most ancient constellations in the sky. Archaeological evidence suggests that as early as 4000 BC, the people of Mesopotamia had observed a constellation similar to Leo. The Persians referred to it as Shir (Sher), the Babylonians called it UR.GU.LA (“great lion”), the Syrians knew it as Arya, and the Turks named it Artan.

The Babylonians were aware of the star Regulus, which they believed to be “the one at the lion’s breast” or “the star of the king.” This constellation and its brightest star have left their mark on various cultures.

The Greeks associated Leo with the Nemean lion that Hercules had slain. This tale served as one of his legendary feats. Both Eratosthenes and Hyginus wrote that the lion was placed in the sky because it was considered the king of all beasts.

The legendary lion resided in a cavern located in Nemea (southwest of Corinth). It posed a threat to humanity as it would prey on humans. Attempts to slay the lion proved futile, as its hide was impervious to any known weapon. Heracles attempted to use arrows, but they merely rebounded. Eventually, he lured the lion into the cave and strangled it. Utilizing the creature’s claws, he skillfully removed the skin and fashioned it into a protective cloak.

In the night sky, there are six radiant stars arranged in the form of a sickle, symbolizing the lion’s head. The most brilliant of these stars, known as Regulus, represents the lion’s heart. Danebola signifies the tip of the lion’s tail, while Algieba, despite its name translating to “forehead,” actually designates the lion’s neck. Lastly, Zosma denotes the lion’s rump.

Main celestial bodies

Discover the shining celestial bodies of the astrological constellation Leo with comprehensive descriptions and categorization.

Regulus (Alpha Leo) – Being the first brightest star in the constellation and the 22nd brightest in the entire sky, it possesses an apparent visual magnitude of 1.35. Situated at a distance of 77 light-years, it is a four-star system comprising two pairs of stars.

Regulus A is a binary star system with a spectroscopic double star. It consists of a blue-white star (B7 V) on the main sequence and a companion star that is considered a white dwarf. These stars orbit around a common center of mass every 40 days.

The primary star Regula A is a youthful star, with an approximate age of a few million years and a mass 3.5 times that of our Sun. It rotates at a remarkably high speed (taking approximately 15.9 hours to complete one rotation), which has resulted in its formation into a flattened shape. If it were to spin just 16% faster, the gravitational force would be insufficient to counteract the centrifugal force, leading to its collapse.

Regulus is the nearest bright star to the ecliptic plane, which means that it is frequently obscured by the Moon and occasionally by Mercury and Venus. In the northern hemisphere, it is most visible during the evening in late winter and spring. However, it is not observable on August 22 due to its proximity to the Sun.

The term “Regulus” is derived from Latin and translates to “little king” or “prince”. The Greek equivalent was “Basiliscos”, which shared the same meaning, while the Arabic name “Kalb al-Asad” signifies “heart of the lion”.

Denebola, also known as Beta Leo, is a main-sequence star of spectral type A3 V. It has an apparent visual magnitude of 2.113 and is located at a distance of approximately 35.9 light-years from Earth. Within the constellation Leo, Denebola is the second brightest star and ranks 61st in terms of overall brightness in the night sky. Notably, it can be easily located without the aid of technological instruments.

In terms of physical characteristics, Denebola is 75% more massive than our Sun and has a radius that is 173% larger. Additionally, it shines with a luminosity that is 12 times greater than that of the Sun. Denebola is classified as a variable star of the Delta Shield type, meaning its brightness can fluctuate slightly over a period of several hours. These changes in luminosity amount to a magnitude difference of 0.025, occurring approximately 10 times a day.

With an estimated age of less than 400 million years, Denebola is relatively young. Its rapid rotation speed of 128 km/s has caused it to develop a flattened shape. Moreover, the presence of significant infrared excess suggests the existence of a dust disk in orbit around Denebola.

IC 2391 refers to a cluster of stars that share a common motion but are not bound by gravity. This cluster also includes Alpha Painter, Gomeisa, and other stars in the open cluster IC 2391. The name “Denebola” comes from the Arabic phrase ānabab al-asad, which means “tail of the lion.”

Gamma Lion, also known as Algieba, is a double star consisting of a giant star (K1-IIIbCN0.5) and a companion star (G7IIICN-I). The giant star is 180 times brighter than the Sun, with an apparent visual magnitude of -2.28. The companion star is 50 times more luminous than the Sun, with an apparent magnitude of 3.51, and is 10 times larger in diameter. The two stars have an orbital period of 500 years. In November 2009, astronomers discovered a planet orbiting the giant star.

With a distance of 130 light years and a total apparent visual magnitude of 1.98, Algieba is easily visible even in a small telescope. Under optimal conditions, both the red and greenish components can be observed. The name “Algieba” derives from the Arabic word for “forehead”.

Algieba, together with Zeta Leo and Eta Leo, is sometimes referred to as the Sickle.

Zosma, also known as Delta Lion, is a white main-sequence star (A4 V) with a visual magnitude of 2.56. It is located 58.4 light-years away. In terms of size, it is about 214% of the radius of the Sun and shines approximately 15 times brighter. In around 600 million years, it will evolve into a red giant. The star’s rotation speed is approximately 180 km/s, which results in a flattened shape and a wider equator compared to the poles.

It is possible that it is a member of a moving cluster of stars in the Big Dipper, which are stars that share a common origin and move together in space. The ancient Greek word “Zosma” means “belt” and refers to its location on the thigh of the lion.

Hort, also known as Theta Lion, is a white main-sequence star (A2 V) with a visual magnitude of 3.324, making it visible to the naked eye. It has a mass 2.5 times that of the Sun and is located 165 light years away from us.

Unlike the Sun, Hort is relatively young with an age of 550 million years. It emits a significant amount of infrared radiation, indicating the presence of a dust disk surrounding it. The star rotates at a speed of 23 km/s.

There are several traditional names for Hort, including Hort (derived from the Arabic word for “small rib”), Coxa (Latin for “thigh”), and Certan (derived from the Arabic words for “two small ribs”).

Kappa Lion is a binary star system (K2III) with a visual magnitude of 4.46 and a distance of 210 light-years. Its traditional name, Al-Minlar, translates from Arabic as “the lion’s face”.

The star Lambda in the constellation of Leo is classified as a K5 star, with a visual magnitude of 4.32 and a distance of 336 light-years. Its traditional name, “Alterf”, is derived from the Arabic word aṭ-ṭarf, meaning “species of the lion”.

Omicron Leo is a binary star system located 135 light-years away. It consists of a giant star (F9III) and a main-sequence star (A5mV), with a visual magnitude of 3.53.

This particular star in the constellation of Leo is a white supergiant (A0 Ib) with a visual magnitude of 3.511 and a distance of 2000 light-years. It is approximately 5600 times brighter than the Sun and has an absolute magnitude of -5.60. This star is believed to be part of a binary system.

Zeta Leo is a massive (F0 III) star with a visible magnitude of 3.33 and a distance of 274 light-years. It shines 85 times brighter than our Sun. It is accompanied by the optical companion 35 Leo, which has a visible magnitude of 5.90 and is located 325.9 arc seconds away from the main star. The name Adhafera originates from the Arabic word al-βafīrah, which translates to “curl” or “braid”.

Rasalas (Mu Leo) is a star classified as K3 with a visible magnitude of 4.1 and a distance of 133 light-years. The term “Rasalas” is derived from the Arabic phrase ra’s al-‘asad aš-šamālī, which means “the northern (star) of the lion’s head”.

Epsilon of Leo is a luminous giant (G1 II) with an apparent magnitude of 2.98 (the fifth brightest in the constellation) and a distance of 247 light-years. It is approximately 162 million years old. The name Ras Elased is derived from the Arabic phrase rās al-‘asad al-janūbī, which means “the southern star of the lion’s head”. It is 288 times brighter than the Sun, 4 times more massive, and 21 times larger in radius. Epsilon of Leo is a variable Cepheid star, exhibiting fluctuations in magnitude of 0.3 every few days.

Rho Lion is a binary star system with an apparent magnitude of 3.856 and a distance of 5000 light-years. The B1 spectral classification indicates that the object has evolved into a supergiant. It has a mass 21 times that of the Sun, a radius 37 times larger, and is 295,000 times brighter. It has a velocity of 30 kilometers per second. The primary component is a blue supergiant, accompanied by a companion located at 0.11 angular seconds and having a visual magnitude of 4.8.

Iota the Lion is a double star that can be observed spectroscopically. It belongs to the F3 V spectral class and has a visual magnitude of 4.00. This star is located at a distance of 79 light-years from our planet. Due to the close proximity of the star system, it is quite challenging to observe it even with the help of a telescope.

Sigma Lion, on the other hand, is a blue-white star classified as B9.5Vs. Its apparent magnitude reaches 4.044, and it is situated approximately 210 light-years away.

Wolf 359 stands out as a red dwarf star of the M6.5Ve spectral type. It has an apparent visual magnitude of 13.54 and is located 7.78 light-years away from Earth. Despite its relatively close distance, Wolf 359 can only be detected with a large telescope. This star is considered one of the least numerous and faintest stars ever discovered. It emits only 0.1% of the sun’s energy, and its mass is about 8% of the sun’s mass, while its radius is around 16% of the sun’s radius. Wolf 359 is relatively young, being less than a billion years old.

Gliese 436, the third closest star to the Sun after Alpha Centauri and Bernard’s Star, is frequently referenced in science fiction literature. Fans of Star Trek will recognize it as the site of a major battle where Starfleet ships were destroyed.

Gliese 436 is classified as a red dwarf (M2.5 B) with a visual magnitude of 10.67 and is located 33.1 light-years away. In 2004, the exoplanet Gliese 436b was discovered orbiting this star, followed by the discovery of UCF-1.01 in 2012.

CW Leo, also known as IRC + 10216, is a carbon star surrounded by a thick dust envelope. It is situated at a distance of 390-490 light-years from the Sun and exhibits variations in brightness over a 649-day period. While its nominal luminosity is 11,300 times that of the Sun, it follows a pulsation cycle ranging from 6250 to 15800 solar luminosity, resulting in an apparent visual magnitude that varies from 1.19 to 10.96.

At an advanced stage of development, the star is shedding its outer layer and undergoing a transformation into a white dwarf. The outer shell, estimated to be 69,000 years old, continues to diminish in mass each year. Experts believe that the expanded shell contains a minimum of 1.4 solar masses of expelled material.

Originally discovered in 1969 by American astrophysicist Eric Brecklen.

R Leo is classified as a red giant (M8IIIe) with a visual magnitude ranging from 4.4 to 11.3 and a period of 312 days. It is approximately 320-350 times larger than the radius of the sun. This star is categorized as a Mira variable, which means it is a pulsating variable star in the later stages of its evolution. It has a deep red color and its pulsation periods can span over 100 days. Eventually, R Leo will shed its outer shell to create a planetary nebula and transform into a white dwarf.

It is located at a distance of 370 light-years. When it is at its brightest, it can be seen with the naked eye. However, in other cases, a telescope with a minimum size of 7 centimeters will be required.

Astronomical Objects

Messier 65 (M65, NGC 3623) is an intermediate spiral galaxy with a visual magnitude of 10.25 and a distance of 35 million light-years. It was first observed by Charles Messier in 1780. Together with Messier 66 and NGC 3628, it forms the well-known Leo Triplet. The galaxy contains very little dust and gas and does not have active star formation. The majority of its stars are old.

The distortion of M65’s disk, as well as the presence of areas with star formation, suggests that the galaxy is interacting with another object.

Messier 66 (M66, NGC 3627) was discovered by Charles Messier in 1780 and is classified as an intermediate spiral galaxy. Its visual magnitude is 8.9 and it is located 36 million light-years away. The galaxy spans a distance of 95,000 light-years. Of particular interest are the dusty streaks and bright star clusters within it. Messier 66 is part of the Leo Triplet, a group of three galaxies.

In the past, M66 and NGC 3628 have experienced a collision. This interaction resulted in a highly concentrated central mass in Messier 66, a high ratio of molecular to atomic mass, and the formation of a non-corrotating cluster of HI material originating from the spiral arm.

This image showcases M66 (NGC 3627) as observed by the Spitzer telescope’s infrared camera. Scientists believe that the distorted shape is caused by its interactions with M65 and NGC 3628.

Messier 95 (M95, NGC 3351) is a massive spiral galaxy with an apparent magnitude of 11.4 and lies at a distance of 38 million light-years. The nucleus is surrounded by a circular region where stars are actively forming, spanning approximately 2000 light-years in diameter.

M95 is part of the M96 cluster, which also consists of M96, M105, and 9 other galaxies. Astronomer Pierre Mechene discovered the galaxy in 1781, and just 4 days later Charles Messier included it in his catalog. In March 2012, scientists observed a supernova in this region.

The Galaxy M95 is positioned towards us, providing a spectacular sight of its spiral structure, where the arms create a nearly flawless circular shape. Its appearance bears a resemblance to the majestic mane of a lion. What truly stands out is the shimmering golden core, surrounded by a ring that spans almost 2000 light-years and is actively forming stars.

Pierre Mechene discovered it on March 20, 1781, and a couple of days later it was included in Charles Messier’s catalog. In May 1998, astronomers observed a Type Ia supernova, known as SN 1998bu.

M96 is the biggest galaxy in the M96 group. When its spiral arms are taken into account, it has a diameter of 100,000 light-years, just like the Milky Way. Any minor imperfections can be explained by interactions with other members of the group or past collisions.

Messier 105 (M105, NGC 3379) is an elliptical galaxy with a visual magnitude of 10.2 and a distance of 32 million light-years. It contains a supermassive black hole. Pierre Mechene discovered it in March 1781, a few days after discovering M95 and M96.

NGC 3628 is a spiral galaxy located 35 million light-years away from us. William Herschel discovered this galaxy in 1784. One of the remarkable features of this galaxy is its long tidal tail, which stretches for 300,000 light-years. Additionally, there is a wide band of dust that obscures the outer edge of the spiral arms. NGC 3628 is also known as a member of the Lion Triplet.

NGC 3628 is captivating not only due to its spiral structure, but also because of the presence of a dark band of dust that stretches across the disk’s plane, which has been slightly distorted as a result of its interaction with neighboring galaxies. This unique X-shape is formed by young stars, gas, and dust, all of which contribute to the formation of the galactic bulge. In 1966, this galaxy was designated as a member of the Atlas of Special Galaxies under the name Arp 317, as it did not fit within Hubble’s standard classification system.

The Lion’s Ring is a massive ancient collection of hydrogen and helium gas that encircles two galaxies. It was first observed by radio astronomers back in 1983.

NGC 3607 is a spiral galaxy with a visual magnitude of 10.8. It belongs to the NGC 3607 group of galaxies.

NGC 3593 is a spiral galaxy with a visible magnitude of 12.6.

NGC 3384 is a galaxy in the shape of an ellipse that is located 35.1 million light-years away from Earth. It was first observed by William Herschel in the year 1784. The central region of the galaxy primarily consists of very old stars. More than 80% of these stars are of the second generation and have an age of over one billion years. NGC 3384 is part of the M96 group of galaxies.

NGC 3842 is another example of an elliptical galaxy. It is known for hosting one of the largest black holes ever discovered, which has a mass equivalent to 9.7 billion times that of our Sun. The galaxy has an apparent magnitude of 12.8 and is located approximately 331 million light-years away from us.

NGC 3596, on the other hand, is classified as an intermediate spiral galaxy and has a visual magnitude of 12.0. It was also first observed by William Herschel in 1784. If you want to locate this galaxy, you should look for it near the bright star known as Theta Leo.

NGC 3626 is a spiral galaxy with a medium-density and a visual magnitude ranging from 10.6 to 10.9. Situated approximately 70 million light-years away, it is positioned near Delta Lion (Zosma). NGC 3626 is a part of the NGC 3607 group.

Discovered on April 5, 1864 by German astronomer Albert Mart, NGC 3357 is an elliptical galaxy.

If you want to explore the zodiacal constellation Leo more extensively, you can utilize not only our photographs but also 3D models and an online telescope. For those who prefer independent exploration, a starry sky map will suffice.

Other heavenly bodies

The constellation contains several spiral galaxies, namely M 65, M 66, M 95, M 96, NGC 3628, NGC 3596, NGC 2903, NGC 3626, NGC 3607, and NGC 3593.

In addition, Leo is home to a number of elliptical galaxies such as M 105, NGC 3384, NGC 3842, NGC 3357.

Interestingly, scientists have recently made a discovery known as the Lion’s Ring. It happens to be a massive cloud made up of helium and hydrogen.

Constellations

In ancient times, the star cluster in the tail region was known as the Tassel. However, it was later recognized as a constellation and given the name Veronica’s Hair.

Furthermore, among the six main stars of Leo, there is a well-known constellation known as the Sickle. Its shape is often likened to an inverted question mark.

Mythology

There are numerous tales regarding the origin of the Leo constellation.

One such legend is from ancient Greek mythology and revolves around the Lion of Nemea. According to the myth, Heracles successfully defeated the formidable beast and offered it as a sacrifice to Zeus. This was in fact one of the earliest known deeds of Hercules. In recognition of his son’s victory, Zeus transformed the creature into a constellation, ensuring that the triumph would be forever remembered by mankind.

Furthermore, ancient civilizations often linked celestial bodies with seasonal occurrences. Consequently, the Egyptians designated the stars of the Lion constellation based on the time when they radiated brightly in the heavens. This was during the peak of intense heat, when the desert transformed into the domain of the mighty king of beasts.

Moreover, there is a connection to the tale of the genesis of the principal star – Regulus. As commonly known, its name signifies the Lion’s heart.
