A Cepheid star is a specific type of star that fluctuates in brightness, pulsating in a radial manner and simultaneously altering its size and temperature. In this scenario, the luminosity of the star varies consistently over a defined period and by a specific degree. Cepheids play a crucial role in determining distances within galaxies and…
Beginners often underestimate the significance of the eyepiece, mistakenly believing that the objective lens diameter is the most important aspect of a telescope. However, selecting the appropriate eyepiece can greatly enhance the telescope’s capabilities for various types of observations. In this article, I will discuss the nature of eyepieces, their variations, and the ideal eyepiece…
Mercury is the nearest planet to the Sun, and it never strays more than 30 degrees from it. This proximity enables the celestial object to complete two orbits around the fiery heart of the universe in a single year. Interestingly, Earthlings can only see one side of the Sun’s closest planet in the solar system….
Every well-informed individual is aware of the process through which a classical planetary system originates. It unfolds as follows: a rotating disk composed of gas and dust suddenly begins to contract on its own. Over time, it accumulates a certain density. Within its core, conditions materialize that enable a thermonuclear reaction to occur. During this…
Throughout history, individuals have always had an abundance of inquiries when it comes to observing the celestial sphere. What exactly are those twinkling dots in the night sky? Why does the sun rise and set, causing the transition from day to night? Could there possibly be other planets in close proximity, and if so, is…
In the early 17th century, Galileo revolutionized the study of astronomy by enhancing the existing telescope and directing it towards the sky. It was one of Galileo’s acquaintances who coined the term telescope, which signifies “far-seeing.” Illustration 160. Page from the manuscript of Galileo documenting his observations of the moons of Jupiter In the early…
A celestial coordinate system is utilized to determine the precise location of a celestial body. These systems, known as the ecliptic coordinate system or equatorial coordinate system, are constructed based on specific circles of the celestial sphere. In contrast, the geographic coordinate system is employed to determine coordinates on the Earth’s surface. Let’s explore each…
The discussion regarding the proponent of the idea that the Earth possesses a spherical shape persists to this day. There still exist individuals who endeavor to substantiate the notion that the Earth is flat, disregarding even the visual evidence of the globe captured in photographs taken from outer space. Thus, the concept of the Earth’s…

Sunrise and sunset are natural phenomena that occur regularly in our Universe. In reality, the Sun does not actually rise or set, but remains stationary. Contrary to what our ancient ancestors believed, it is not the celestial luminary that revolves around our planet. Instead, it is the Earth, along with the other seven planets, that…
The moon is currently in the New Moon phase with an age of 1.31 days.It is rising at 07:17 and will set at 21:27. Zodiac Sign Full Moon The upcoming full moon is scheduled to take place on August 31, 2023. New Moon The next new moon is expected on September 15, 2023. In St….
Tungsten carbide is a tool used for drilling shallow holes ranging from 2 to 10 mm in diameter in soft wood. The tungsten carbide drill has a spiral cutting edge along its shaft. It has a fine screw thread at the end, which allows it to be screwed into the wood while rotating. However, tungsten…
Astronomy may not hold direct importance for every individual, but our collective curiosity has led to significant technological advancements for our planet. The Definition of Astronomy Put simply, astronomy is the scientific study of the sky and celestial bodies. In ancient times, astronomers observed and analyzed everything occurring in the sky above the clouds –…
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….
The Earth’s moon is a natural satellite that orbits around our planet. It holds the distinction of being the closest satellite to the Sun, as neither Mercury nor Venus possess any satellites of their own. Once the sun sets, the moon is the second most luminous object visible in our sky. When considering its size,…
Virgo is positioned on the ecliptic and is the most extensive constellation within the zodiac. It is also one of the largest constellations in the entire sky. Spanning an area of 1,294 square degrees, it is surpassed in size only by the constellation Hydra which covers 1,302 degrees. Virgo is surrounded by Hydra, Libra, Leo,…
The allure of the night sky has always captivated explorers, with many people dreaming of discovering a star or constellation and naming it after a loved one. Here, I present a concise guide that consists of two sections, offering a detailed explanation of how to construct a wooden telescope entirely by hand. Specifically, this section…
The nearest star to Earth is Proxima Centauri. In the past and future, there have been and will be other stars that are close to Earth. There is a list of stars that are closest to Earth. What star is the closest to Earth? Many people immediately think of Alpha Centauri, Sirius, or even Polaris….
When an average individual, lacking profound knowledge in astronomy, acquires a telescope, they typically assume its primary function is magnification. However, this perspective on the device is misguided, as a telescope is primarily designed for the purpose of collecting starlight. Consequently, the more effectively the instrument fulfills this role, the greater the potential for the…
By utilizing the Full Moon in June 2021, you can easily determine the current phase of the Moon and understand its impact on various aspects of life. The lunar calendar provides valuable information about the Moon’s transit through the zodiac signs, including the exact time of entry into each sign and the start of each…
