Constellations "When it comes to the Virgo constellation, the stars in the head area, as well as the star at the end of the southern wing, have a striking resemblance to Mercury and, to a lesser extent, to Mars; the other bright stars in the wing and those in the belt have similar appearances to…
When students reach the 2nd grade and start studying the subject “Surrounding World,” one of the constellations they become familiar with is the Big Dipper. Mastering the skill of locating the star formation known as the “bucket” in the dark sky is crucial for children, as it serves as a guide for spotting numerous other…
In ancient times, scientists began to realize that it is not the Sun that revolves around our planet, but rather the opposite is true. This groundbreaking idea was solidified by Nicolaus Copernicus. The Polish astronomer developed his heliocentric system, which convincingly proved that the Earth is not the center of the Universe. According to Copernicus,…
Stars, despite appearing eternal and unchanging to us Earthlings, actually undergo a gradual process of evolution. In this article, we will explore the various stages that stars go through during their lifespan. Phases of stellar development Every transformation is driven by certain factors that induce the system to undergo change. In the case of stars,…
On the morning of June 30, 1908, an extraordinary event unfolded above the Podkamennaya Tunguska river basin in Eastern Siberia. A magnificent fireball suddenly materialized and streaked across the sky, followed by an intense burst of light and a series of deafening explosions. One eyewitness even claimed that the heavens themselves seemed to split in…
The Ursa Minor is a well-known constellation that is easily recognizable, despite its unassuming appearance. One of the reasons for its popularity is the presence of Polaris, the North Star, which has long served as a guiding light for travelers. Location and Description The Ursa Minor is located in the circumpolar region, making it visible…
Constellations The constellation known as Little Lion can be found in the northern hemisphere of the sky. Covering an area of 232 square degrees, it boasts 34 stars that can be seen without the aid of a telescope. This particular constellation is a favorite among stargazers, as it is a common location for comet sightings….
In the middle of the 18th century, the English geologist John Michell brought attention to the potential presence of black holes in the universe. Michell hypothesized that if a star possessed the same density as the Sun but was 500 times smaller in size, its first cosmic velocity would surpass the speed of light. As…
Earth’s atmosphere is a gas shell that surrounds the planet, extending for a certain distance from its surface. The atmosphere covers the hydrosphere and part of the Earth’s crust, and its outer surface meets the near-Earth region of outer space. The scientific disciplines of atmospheric physics, meteorology, and climatology are dedicated to studying the different…
Giant planets are a category of massive planets that lack a solid surface. These celestial bodies are frequently accompanied by numerous satellites. The Solar System contains four giant planets, namely Jupiter, Saturn, Uranus, and Neptune. These massive entities rank as the largest objects in our solar system, second only to the Sun. In this article,…
The moon is the only celestial object in our sky that visibly changes its shape. While the sun always remains the same – round and incredibly bright (except during rare eclipses) – stars and planets typically maintain their shape, unless observed with a telescope. The appearance of the moon, however, undergoes distinct transformations, resembling a…

How long will it take for the Earth’s core to “run out of fuel”? Experts suggest that the temperature of the Earth’s core is even higher than the temperature of the Sun’s surface, reaching up to 10,000°C. Located beneath the Earth’s crust, there exists an extremely hot region with soaring temperatures – the Earth’s core….
The length of the night is increasing and the duration of the day is decreasing as we move into October, following the autumnal equinox. As a result, the sunrise is becoming progressively later. Furthermore, October brings about a change in the constellations that are visible in the night sky, replacing those of the summer months….
When I was a child, time seemed to move at a glacial pace. I remember fantasizing about ice skating during the summer and swimming in the river during the never-ending winter. As I got older, I realized that our vast planet experiences different seasons throughout the year. We have harsh winters and scorching summers, pleasant…
"If you enter a black hole, the energy of your mass will come back to our world, but in a distorted form," as famously stated by the renowned British physicist, Stephen Hawking. The Milky Way galaxy is home to an immense number of stars, including our very own Sun, as well as interstellar gas that…

The stratosphere, derived from the Latin word “stratum” which means planking or layer, is a specific layer of the atmosphere that exists at an altitude ranging from 11 to 50 kilometers. It is characterized by a minimal change in temperature within the range of 11-25 kilometers (known as the lower stratosphere layer), and a gradual…
How did the universe we are familiar with come into existence? And how can we account for its inception? Undoubtedly, all the other evidence and facts that cosmologists have amassed throughout the years indicate that it may have all originated from a “big bang.” However, what if there is more? In 1927, Georges Lemaître, a…
The distance from Earth to space, as measured in kilometers (km), is approximately equal to the distance from the planet’s surface to the outer edge of its atmosphere, where the vast expanse of the cosmic vacuum begins. In the 1970s, the Gemini 11 spacecraft reached a record altitude of 1,372 kilometers in its attempts to…
