Messier 91 galaxy, missing  since 1781, was found by amateur astronomer in 1969

Barred spiral galaxy Messier 91 (M91) lies in the constellation of constellation of Coma Berenices. The galaxy’s bar stands out quite noticeably. The galaxy represents the faintest object in Charles Messier’s catalog, and he discovered it in 1781. Notably, a rare error by Messier caused the galaxy to go “missing” for centuries, until amateur astronomer […]

[CLICK ON IMAGE FOR HIGH RESOLUTION /  Rogelio Bernal Andreo] Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie about 1,500 light-years away, born of Orion’s well-studied interstellar clouds. In fact, clouds of gas and dust adrift in this region have […]
