When gazing at the celestial expanse, few ponder the fact that the stars we see today are actually images from the past, captured hundreds, thousands, or even millions of years ago. That is the incredible amount of time it takes for light to travel from a distant star to our planet. Many of the stars…
The impact of Claudius Ptolemy on the field of science cannot be overstated. His contributions to astronomy, physics, mathematics, geography, and even music have not only been influential but have also served as a catalyst for the advancement of these disciplines. While much literature exists on Ptolemy’s achievements, there is a notable absence of biographical…
Reply from Milena [active].Mercury appears gray because it lacks an atmosphere and water, consisting primarily of rock. Venus, on the other hand, has a yellowish white hue due to the clouds surrounding the planet, which are formed by the vaporization of hydrochloric acid. Earth, often referred to as the “Blue Planet,” is predominantly blue with…

This section will explore the concepts of satellites and their orbits, focusing on the main types. During the past 50 years of the space era, the number of satellites in near-Earth space has grown significantly. There are now tens of thousands of objects ranging in size from the International Space Station (ISS), which measures more…
There is a special event On October 4, 1957, the first ever man-made satellite was sent into orbit around the Earth, marking the beginning of the space age in human history "The initial groundbreaking achievement for humanity is to transcend the atmosphere and become a satellite of our planet. Everything else becomes relatively easier, even…
The Orion constellation is easily identifiable in the equatorial sector and stands out in the night sky. Once you spot the constellation, it becomes easy to locate it again later. Overview Orion is among the most brilliant constellations visible from Earth. It forms a symmetrical human figure comprising seven stars. In the center, there are…
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…
The solar system is composed of more than just the sun and the planets that orbit it. It also contains countless asteroids. These are celestial bodies that orbit around a star but have a non-spherical shape due to their small size. Usually, asteroids are classified as objects with a linear size greater than 30 meters,…
It may appear that exoplanets and relic radiation are essential, and the selection of candidates is evident. However, upon further investigation, we discovered that the Nobel Committee’s choice in Physics was rather peculiar. Relict radiation has greatly influenced our perspective on the development of the cosmos. / CCO Public Domain. The Nobel Committee has recognized…
It’s easy to overlook the enormous impact that satellites have on our daily lives. Without them, many essential services that we take for granted, such as long-range weather forecasts and navigational systems, would be impossible. Satellites have also revolutionized modern warfare, enabling us to gather intelligence and monitor enemy movements from afar. They even play…
On numerous occasions, when gazing up at the nighttime sky, we have pondered – what lies within this boundless expanse? The cosmos hides numerous enigmas and puzzles, but there exists a scientific field known as astronomy, which has dedicated itself to investigating the universe and unraveling its beginnings. So, what exactly is this discipline? What…

Celestial systems of coordinates are systems of coordinates that are used to describe the location of a celestial object on the celestial sphere. Typically, spherical coordinate systems are used, which describe the position on a given sphere using two angular quantities. In the case where the distances to the celestial objects are known, Cartesian coordinate…
In an exciting announcement on February 22, 2017, NASA revealed the discovery of seven exoplanets orbiting the star TRAPPIST-1. Among these planets, three are positioned at a distance from the star that could potentially support liquid water, an essential element for life as we know it. It is worth noting that this star system is…
It is crucial to follow the warning on your telescope that says, “Never point the telescope at the Sun!” This warning is usually in the form of a bright sticker or label on the tube. However, with proper preparation, you can safely observe the Sun using your telescope. This article will guide you through the…
In order to gain insight into the fascinating world of space, we reached out to a group of passionate students and young researchers. Among them, Alexander Sabitov, a master’s student from the Department of Theoretical Physics at P.G. Demidov Yaroslavl State University, delved into the topic of star death during his lecture series. He shed…
Throughout history, scientists from various regions of the world have developed numerous hypotheses to explain specific processes, phenomena, and occurrences. Some of these hypotheses were quickly proven or disproven through practical experimentation. Others remained purely theoretical for many years due to the limitations of technology at the time.
