Solar system. Hypothesis on the origin of sunspots

In the solar system there are many different types of free celestial bodies that do not have their own orbits. Such bodies can be asteroids, meteorites, comets, as well as free moons that do not belong to the solar system. In Space, there is also enough “garbage” – debris destroyed by a collision or explosion of celestial bodies. It has long been known that meteorites and other celestial bodies often fall on Earth, moons, and other planets. The earth and other planets are well protected from such “bombing” with their atmosphere, in which most of the small falling objects burn up. But the moons that do not have an atmosphere are literally dotted with impact craters. For example, the satellite of Saturn Mimas in the photo on the left, taken by Cassini in 2005, almost all is covered with craters from the smallest to the gigantic. The sun is not only an exception, but, on the contrary, due to its gigantic attraction, it is thousands of times more likely to undergo such Continue reading

Planet Venus – History of Research

Venus was known to people from ancient times. (See a brief description of this planet and interesting facts about it.) It received its modern name in honor of the Roman goddess of beauty, whom the Greeks called Aphrodite. The Babylonians called this planet Astarta, also named after the goddess of love. In ancient China, Venus was designated as the “golden star” and associated with the “element of gold.” In ancient India, Sura (Ushanas Kawya), the mentor of the asura demons, rivals of the Indian gods, was considered the lord of Venus.

Venus rises in the sky either in the evening or in the morning. The ancient Greeks long considered the “evening” and “morning” star two different bodies, calling the first Hesperus (“Evening”), and the second Continue reading
