history

As early as 5000 years ago, there was an astrological description of Capricorn, which is a sheep in the sea. Capricorn is considered as the gateway to heaven for the human soul. This southern constellation is very big and eye-catching, although it does not have a bright star. Its outline is quite clear and easy to distinguish in the dark night. Although Capricorn is very big, there are not many interesting stars for astronomy lovers, and the galaxies in this area are also very weak and insignificant. Capricorn has a globular cluster M30 in the messier objects.

astrology

Capricorn α: This is a binary star visible to the naked eye, which can be seen more clearly with binoculars. It is an optical binary star, and the two sub-stars are not physically connected, but because the two stars are in the same direction, it gives people the impression that the two stars are together. If you look through a telescope, you will find that each sub-star is a binary star. α 1 consists of two stars with magnitudes of +4 and +9 respectively, and the two sub-stars are 45 arc seconds apart. α2 is more difficult to observe, and its two sub-stars are +3.5 and+1 1 respectively, which are about 6.6 arc seconds apart.

Deep sky object

M30: This is a globular cluster with a magnitude of +7.5. Observed with a small telescope, it is only 5 arc minutes in size. To see clearly, you must use a 6-inch (15cm) telescope. It is 24,000 light years away from the Earth, and there are two rows of inconspicuous stars in the north of the center of this cluster.

The myth of Capricorn

In Greek mythology, there was a shepherd named Paine, who could play the horn flute. He is ugly, and has the god of goat horn, sheep hoof and goatee. His father is Hermes, the messenger of the gods. Paine once attended a banquet for the gods by the Nile River and played for them at the banquet. Unexpectedly, during the performance, his flute attracted monsters from ancient times. At this time, the gods fled one after another. Paine jumped into the Nile in a panic because he was playing, trying to escape like a fish, but he was in a hurry and his transformation was not completed. As a result, the lower body was soaked in water and turned into a fish tail, while the upper body remained the original goat appearance. Zeus saw Paine in the sky and thought it was very interesting, so he turned it into a constellation in the sky.
