Natural solid objects known as meteoric bodies, or meteoroids, make their way towards the Earth’s atmosphere at an astonishing speed exceeding 150,000 km/h. As they enter the atmosphere, they experience friction which results in intense heat and combustion. Astronomers refer to the visible trail left by a meteoroid as a meteor, with the brightest examples…
Most likely, every child at some point attempted to comprehend constellations and commit their names to memory. My fascination with the stars began after watching an old Soviet cartoon about the Minotaur. Towards the end, Dionysus abducts Ariadne, and they present an image of the sky featuring the corresponding constellations. However, despite my best efforts,…
The Earth’s lithosphere is a rigid outer layer that encases the planet. It acts as a shield, safeguarding the surface from extreme temperatures emanating from the planet’s core. Exploring the composition and characteristics of the lithosphere can provide insights into its distinctions from other celestial bodies. Key features The lithosphere is situated between the hydrosphere…
The solar system consists of a collection of planets orbiting around the Sun, a star that is significantly larger and more massive than them. In addition to the planets, the solar system also comprises their moons, asteroids, comets, and numerous meteoric components. The Star An image of the Sun captured using the H-alpha line is…
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…
On December 15, 2022, there was a breach in the instrumentation compartment of the Soyuz MS-22 manned spacecraft, resulting in a release of coolant into space. The same issue occurred again on February 11 with the Progress MS-21. Today, on March 28, the descent vehicle of the Soyuz MS-22 spacecraft, which had previously undocked from…

Yuri Gagarin, a Soviet citizen, became the first human to travel to space. On April 12, 1961, he launched from the Baikonur Cosmodrome aboard the Vostok-1 satellite spacecraft. During the 1 hour and 48 minute (108 minutes) flight, Gagarin completed one orbit around the Earth. Following Gagarin’s historic achievement, American astronauts Alan Shepard Jr. and…
The center of the Milky Way has witnessed the most intense burst of energy ever recorded by astronomers. The supermassive black hole at the heart of our galaxy has unexpectedly become more active, leaving scientists puzzled as to the cause of this phenomenon. In this article, we will delve into this discovery and explore the…
Nevertheless, the term “merge” is a more accurate description, considering the highly dispersed arrangement of matter within galaxies, which makes the likelihood of stars or planets colliding highly improbable. Based on one hypothesis, the Milky Way and its nearest galactic companion Andromeda have already merged. Alternatively, another theory suggests that our Galaxy is heading towards…
The World Pole is a fixed point on the celestial sphere where the stars appear to rotate due to the Earth’s rotation.
