The sizes of the planets in the solar system differ both within and among different groups. The gas giants, for instance, are significantly larger and more condensed compared to the planets in the Earth-group. In terms of proximity to the Sun, the order is as follows: Hermes, Aphrodite, Earth, Mars, Jupiter, Saturn, Sky, and Neptune….

The celestial body known as Earth is situated as the third planet from our star, the Sun, positioned in the space between Venus and Mars. It holds the distinction of being the most compact planet within the solar system, as well as being the largest member of the terrestrial group of planets. Moreover, Earth is…

In contemporary astronomy, constellations are defined as distinct regions of the celestial sphere that serve as navigational reference points. However, in ancient times, the term “constellation” held a different meaning. Our ancestors referred to constellations as groupings of stars in the sky that formed unique shapes and memorable figures. This approach to the study of…

You have likely witnessed the phenomenon of Estrella Fugaz and have performed the customary act of making a wish. Shooting stars can be observed on a cloudless night, amidst a celestial backdrop, particularly during specific periods throughout the year. However, what exactly is a shooting star? Is it potentially dangerous? And what is its source…

During the final stages of its life cycle, a red supergiant star experiences significant instability, leading to the expulsion of a substantial amount of gas. This expulsion is then followed by a powerful explosion, resulting in the creation of a supernova star. advertisement In a groundbreaking development, scientists have recently witnessed the demise of a…

The constellation Hound Dogs, also known as Canes Venatici, is situated in the northern hemisphere. Its name is derived from Latin, where “Canes Venatici” translates to “Hound Dogs.” This constellation represents the two dogs, Asterion and Chara, that were said to follow the Wolfhound. While Ptolemy initially included the stars of Hound Dogs in the…

For a long time, humanity’s efforts to explore the Moon were limited to visual examination using optical instruments. In 1959, a new phase in the exploration of Earth’s natural satellite began with the successful landing of the Soviet automated station Luna-2. Ten years later, American astronaut Neil Armstrong became the first person to step foot…

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…

The issue of determining the distance between the Moon and the Earth has been resolved for a long time. In ancient times, it was a matter of debate as science did not provide a clear answer. However, it is now known that the Moon is not larger than the Earth. This article provides valuable information…

The University of Manchester, UK, led by Professor Albert Zylstra, has made a groundbreaking discovery regarding the temperature of stars in our galaxy. They have found that there are stars with incredibly low temperatures. In fact, one star in particular has a surface temperature that reaches as low as 2-3 thousand Kelvin. When it comes…

+7 926 604 54 63 address We offer a selection of celestial objects that can be easily spotted and observed using binoculars or even just the naked eye. Instead of focusing on individual stars, we will be discussing “deep sky objects” (DSOs), which include nebulae, star clusters, and galaxies that are not too far away….

Objective: The aim of this lesson is to establish a comparison between the components of the Earth’s sphere and the celestial sphere, to enhance focus and communication skills, and to improve independent learning abilities. The goal is to develop the ability to utilize the horizontal coordinates of celestial bodies in solving qualitative problems. Download: Preview:…

For numerous novice stargazers, Venus is a captivating celestial body to behold through a telescope due to its effortless detectability in the nocturnal expanse. Indeed, it ranks among the most radiant astral entities, second only to the Moon and the Sun! How to locate Venus in the sky Referred to as the “evening star” or…

There are prevailing theories that, while not entirely inaccurate, fail to fully explain the phenomenon. It is true that upon entering the Earth’s dense atmosphere, the outer layer of a meteorite heats up. Without proper thermal insulation, the meteorite would inevitably disintegrate. This explains why many meteor bodies do not reach the Earth’s surface. However,…

Interestingly enough, not everyone will be able to answer the question of which planet is closest to Earth. However, the answer is quite simple – Venus. It is the second planet from the Sun, while Earth is the third. The distance to its other neighbor, Mars, is much greater. When Venus and Earth come close…

The following equations provide an estimate of the potential capabilities of a telescope. It’s important to note that these equations are theoretical and actual performance may vary based on the quality of the telescope, proper calibration, and atmospheric conditions. The telescope’s magnification (G) G=F/f where F represents the focal length of the objective lens and…

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…

For over a century, scientists have been analyzing the dimensions of our planet. The ancient Greeks, including notable figures like Aristotle, Pythagoras, and Eratosthenes, attempted to calculate its size, shape, and structure. The study of the Earth has spanned centuries, with advancements in science and technology leading to a better understanding of its internal makeup….

Astronauts are constantly present on the International Space Station all year round. Recently, Oleg Novitsky and Pyotr Dubrov were dispatched from Russia to orbit the Earth. They departed from the planet a couple of months ago and are scheduled for a significant spacewalk on June 2. At 8:40 Moscow time, the Russian astronauts will venture…
