On October 4, 1957, the Soviet Union achieved a groundbreaking milestone by successfully launching the world’s first artificial satellite. This historic event marked the beginning of human exploration of outer space. In honor of the 60th anniversary of this significant achievement, the team at TASS-DOSSE has prepared a detailed article highlighting the history of the…
The Great Dipper is undoubtedly the most well-known formation in our celestial sphere. It has gained its popularity due to its distinct shape, memorability, significant brightness, and, most importantly, its constant presence above the horizon in our latitudes. In other words, the dipper is perfectly suited to serve as a guide to other constellations and…
It is a unique occurrence for a solitary celestial body to possess the distinction for multiple characteristics simultaneously. However, there exists a star that has managed to achieve this feat. Presently, it holds the title for the most brilliant star in the entirety of the cosmos – in addition to being the most massive and…
Situated between the orbits of Mercury and Earth, Venus has become a subject of extensive exploration due to its prime position for observations. What intriguing details can we uncover about this celestial body known as the “morning star”? Similar to Earth Venus is often referred to as the “sister planet” of Earth due to its…
So, what exactly is a parade of planets? It’s not just a made-up concept, but rather an astronomical event where a certain number of planets in our solar system align in a straight line with a slight deviation of 20-30 degrees from the Sun. This means that they appear very close to each other in…
It has been two years since the Chelyabinsk meteorite fell. On February 15, 2013, at 9:20 am, the meteorite entered the atmosphere at a steep angle and left a distinct white trail behind. The “tail” of the bolide was captured by thousands of photo and video cameras, and the actual space object was retrieved from…
“Making reading a habit is an error,” explains Philip Marcus, a professor of mechanical engineering at the University of California, Berkeley, who specializes in computational physics, as we sip on our coffee at a local café. “You become too familiar with the subject matter. That’s how I became captivated by the intricacies of fluid dynamics.”…
During our time in school, we were introduced to the solar system. At the center of it all is the Sun, around which all the planets orbit. Initially, it was believed that there were nine planets, including Pluto. However, Pluto was later excluded from the list due to its smaller mass and gravitational field compared…
A reflector telescope is a device used to amplify the size of faraway objects or to increase the intensity of point objects like stars. A basic refractor telescope is composed of two convex lenses: an objective lens and an eyepiece. The objective lens creates the true image of the distant object in its focal plane….
The International Space Station (ISS) crosses our path multiple times daily, but it only becomes visible under specific circumstances. The ISS is illuminated by the Sun and, when it passes at a certain distance, it reflects sunlight just like the Moon does. To catch a glimpse of the ISS from Earth, you need to be…
The question of how many stars there are in the sky cannot be answered by even experienced astronomers. However, there is an approximate number that is known. How many stars can the human eye detect? Scientists, on the other hand, have an exact answer to this question. In a large city like Moscow, a person…
The planet Polaris falls into the category of a unique celestial body. Its position in the sky is such that the north pole of our planet is almost aligned with it. As a result, as the Earth rotates, Polaris appears to be stationary while all the other stars revolve around it. This phenomenon makes Polaris…
The night sky is captivating and has mesmerized humanity for thousands of years. We have marveled at the twinkling lights and attributed divine origins to constellations, believing they hold power over our destinies. Even today, the stars continue to enchant us, although we now possess the knowledge to determine their distance and calculate the paths…
Johannes Kepler, a German scientist, was the one who discovered the laws of motion of the planets in the solar system. While studying Nicolaus Copernicus’ system and observing celestial bodies by Tycho Brahe, he was the first to uncover the fundamental laws governing the movement of celestial bodies around the Sun. These laws later became…
The largest known entity in the universe measures 10 billion light years across. Scientists have identified a colossal assembly of galaxies known as the Great Wall of Hercules – Northern Crown as the most expansive structure in the universe. This colossal supercluster is so vast that it takes light approximately 10 billion years to traverse…
Is it possible for extraterrestrial sunsets to be more awe-inspiring than those witnessed on Earth? As we all are aware, the sun’s rays are white in color. These rays are refracted by numerous tiny water droplets present in the atmosphere, resulting in a diverse range of colors and shades. This natural phenomenon gives rise to…
Hello, esteemed readers of the KtoNaNovenkogo.ru blog. I’m sure all of you are familiar with the concept of a light year. The value of this measurement is truly fascinating. Instead of measuring time or days, a light year is a measure of distance. According to the International Astronomical Union, 1 light year is equivalent to…
Which of the major satellites has the lowest temperature, with summers lasting for 42 years, and which of them could potentially be suitable for human habitation? There are a total of 200 satellites in our solar system, with an average of 25 moons for each planet. However, the Earth is an exception with only one…
The solar system is an arrangement of celestial bodies, consisting of a central star, namely the Sun, and various other objects that revolve around it. This astrophysical system has a remarkable age of approximately 4.6 billion years. Its inception can be traced back to the consolidation of a spinning cloud of gas and dust, which…
