The device and operation of different optical devices are based on the principles of geometrical optics. Let’s examine a few of them. An opaque camera and a lens system called a lens are the main components of a camera. The most basic lens is a single collecting lens. This lens forms a real inverted image…
Many books and numerous popular scientific articles have been written about this celestial phenomenon, and countless expeditions have been organized to investigate the epicenter of the catastrophe. However, despite these efforts, no traces of extraterrestrial origin have been found. A team of scientists from Siberia, led by Dr. Sergei Karpov, a doctor of physical and…
What is the size of the moon – the satellite of the Earth. Information about its mass, density, and gravity, as well as its real and apparent size, the phenomenon of the supermoon, the illusion of the Moon, and a comparison with the Earth in photographs. The Moon is the most luminous object in the…
Exactly a decade ago, on February 15th, a meteorite known as Chelyabinsk crashed down in the Urals. Experts claim that it didn’t possess the power to wipe out the entire planet, but it could certainly obliterate a medium-sized town. Fortunately, a stroke of luck led the celestial “rock” to descend into Lake Chebarkul instead, causing…
The constellation known as Orion’s belt is comprised of a trio of stars that align to form a distinctive geometric shape resembling a belt. These stars, named Alnitak, Alnilam, and Mintaka, are located in the central region of the Orion constellation, which takes the form of a mythical hunter. In Greek mythology, this arrangement is…
The Earth is positioned as the eighth planet in our solar system, and it is situated about 150 million kilometers away from the Sun. Along with Mercury, Venus, and Mars, Earth is classified as a terrestrial planet. In contrast, the second group of planets, known as giant planets, consists of Jupiter, Saturn, Uranus, and Neptune….
The constellation Lyra is both small and stunningly beautiful, making it easily recognizable in the night sky. It can be observed throughout the year, and with the help of the brilliant Vega, locating it becomes a breeze. Despite its size, the Lyra constellation offers a wealth of fascinating celestial objects to explore. The tale of…
On January 3, 2010 at 8:53 a.m. local time, a picture was taken of the Sun from Lamlash, Scotland (55° 31′ 47.43″ N, 5° 05′ 59.77″ W). The Sun’s position in the sky depends on the time and geographic location of the observer on Earth’s surface. Due to the Earth’s orbit around the Sun, the…
The concept of what lies beyond the edge of the universe has intrigued both scientists and the general public who have a fascination with the enigmas of the cosmos. The portion of the celestial sphere that is observable to us during the night is merely a fraction of the vast expanse of cosmic space. The…
Due to its relatively low mass, Jupiter is incapable of becoming a star, despite its striking similarity to the Sun. The cosmos is undeniably breathtaking, filled with celestial bodies of incomprehensible proportions. Even with our familiarity with Earth and the multitude of images depicting it, our minds cannot fully grasp the tremendous scale of our…
The celestial event, which will also be visible to the naked eye, is not a genuine alignment of the planets. Unlike last summer, when Mercury, Venus, Mars, Jupiter, and Saturn formed a straight line after an 18-year hiatus, this time the planets will not be positioned in a direct line from the perspective of the…
Constellations Gemini is a constellation located in the northern hemisphere of the sky. It is known for its bright stars, Pollux and Castor. The Sun is positioned within this constellation from June 20th to July 20th. The primary celestial bodies of the Gemini constellation Castor (Alpha Gemini) Castor (Alpha Gemini) – represents a group of…
Outer space The scientific confirmation of the presence of gas giants in the cosmos is an established fact. These celestial bodies are colossal in magnitude, making them relatively easy for researchers to observe. Smaller and more compact entities that reside within the vastness of the universe are referred to as terrestrial planets. Despite sharing certain…
Practically all celestial bodies in the solar system undergo rotation around their central axis. This includes planets, moons, and even asteroids. However, is it possible that the Sun, being a star, also experiences rotation on its own axis? Yes, it does, and there are several unique aspects to this rotation. Firstly, the solar axis is…
Out of the many moons that orbit Jupiter, eight are considered to be permanent satellites. These satellites have ProGrade orbits, meaning they move in the same direction as Jupiter’s rotation, and their orbits are nearly circular and not highly inclined with respect to Jupiter’s equatorial plane. The most famous of these satellites are the Galilean…
There is perhaps no constellation in the northern hemisphere sky that is more well-known than the Little Bear. It is the one that children often inquire about and even attempt to spot in the night sky. Why has it garnered such special attention, considering that the Little Dipper appears rather unassuming? Primarily because it is…
It is estimated that the mass of the dark companion at the center of mass should be around 50 years. However, this statement was met with doubt as the dark companion couldn’t be observed and its mass was expected to be quite large, similar to the mass of Sirius. In the case of red giants…
Amateur stargazers mostly utilize two conventional forms of telescopes for their observations. These include refractors, which use lenses (or objective glasses, as they are often referred to) to construct the image, and reflectors, which employ a mirror for this purpose. Occasionally, catadioptric systems, which are a combination of multiple lenses and mirrors, are utilized to…
Comets are composed of frozen gases, rocks, and dust, and they remain from the creation of the solar system approximately 4.6 billion years ago. These celestial bodies follow elongated orbits around the Sun, which have extremely lengthy durations. When a comet approaches the Sun, it undergoes rapid heating, causing the solid ice to transform directly…
The primary distinction among giant planets is their lack of a conventional solid surface. They exist as enormous spheres, primarily consisting of gas. As a result, they are often referred to as gas giants. Consequently, humans will never be able to stroll upon the surfaces of Jupiter or Saturn, or even on the lunar terrain….
