How many constellations are there in the sky? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? How many constellations are there in the sky? If you look at the stars, sometimes you may think that you see squares, letters and other familiar shapes there. People of the past, in almost all parts of the world, also thought so. They observed groups of stars and gave them names. But it is not always so easy to single out figures in the sky that suggested names. Therefore, one should not expect that the constellations really have the outlines that their names remind of. Greek astronomers listed 48 constellations, and 40 more were identified after them. Thus, there are now 88 constellations in heaven. Not all constellations, of course, can be seen from anywhere on Earth. Some of them are in the sky of the Northern Hemisphere, some are visible only from places south of the equator. As the Earth rotates around the Sun, new groups of stars appear from behind the horizon. The circumpolar constellations, which appear to revolve around the North Star, remain in view throughout the year. In addition, there are constellations that only appear in winter, spring, summer or autumn. Author: Likum A. Random interesting fact from the Great Encyclopedia: What scientific result of William Gilbert the great Galileo called astonishing? English physicist William Gilbert (1544-1603) was the first to suggest that the Earth is a large magnet, and its magnetic poles coincide with geographic Gilbert made a "little Earth" in the form of a magnetized iron ball, and then, circling the surface of this ball with a magnetic needle, investigated its magnetic properties and found that they correspond to the magnetic properties of the Earth - a "big magnet". On the basis of this experience, Gilbert concluded that, from the point of view of the magnetic action, the Earth differs from the iron ball he studied only in its size. Galileo called the scientific and philosophical significance of this conclusion "worthy of admiration." Hilbert was the first person who dared to compare the fact obtained within the walls of the laboratory with the phenomenon of a cosmic order. Thus, he dealt a heavy blow to the thousand-year-old myth that opposed the sublunar world to the heavenly world. Hilbert's concept ultimately meant that the phenomena of the cosmos should be studied by the same methods that are suitable for the study of ordinary terrestrial phenomena.
