When was sagittarius constellation discovered

With a magnitude of 2. Ascella is another binary star system that lies about 90 light years from our solar system. Sagittarius is an important constellation in that it marks the direction of the center of our galaxy. Because it lies in the heart of the Milky Way, it contains more Messier objects than any other constellation in the sky. There are 15 in all, including seven globular clusters, four open star clusters, three nebulae, and an interesting patch of the Milky Way.

M8 is known as the Lagoon Nebula and is one of the most well-known nebulas in the sky. M20, the Trifid Nebula, is famous for its dark dust lane that divides it into three distinct areas. M17, also known as the Omega Nebula or Swan Nebula, is an emission nebula located over 5, light years from Earth.

M22, the Sagittarius Cluster, is a globular cluster that contains over 80, stars. These are the most notable named exoplanet systems known in the constellation Sagittarius. Bear in mind that we will likely discover billions of exoplanets in the years to come.

Also see all exoplanets. For the southern hemisphere, constellations appear rotated degrees upside-down and left-right reversed from what is shown. Remember that seasons are reversed too - summer in northern latitudes is winter in southern latitudes.

Values listed apply primarily to stars. But this was the constellation Centaurus, not Sagittarius. Moreover a Greek astronomer, Erathostenes of Cyrene, challenged the idea that Sagittarius was a centaur at all. He claimed it was another mythological being, Crotus. Crotus was the son of satyr god, Pan. He invented archery and was quite fond of horseback riding. Crotus was a good friend of the Muses. To honor him the gods gave him a place in the heavens as Sagittarius.

The archer is thought of as a centaur, half human, half horse. While astronomers cannot observe a black hole directly, they can observe how it affects the stars around it. That region of space also contains several nebulae, including the Lagoon Nebula M8 or NGC , a large interstellar cloud about 50 by light-years in dimension.

In astrology, which is not a science , Sagittarius is the ninth sign in the Zodiac and represents those born between Nov. The Greeks identify Sagittarius as a centaur, horse-human hybrid with the body of a man atop the four legs of a horse. The creature is aiming an arrow toward its neighbor Scorpio.
