... the most massive stars are by far the shortest lived! For example, according to the mass–luminosity relationship, the lifetime of a 10solar-mass O-type star is about 1/1000 (=10 solar mass/104 luminosity) that of the Sun, or 10 million years. So we can be sure that all the O-type and B-type stars we ...

Corvus (constellation)
Corvus is a small constellation in the Southern Celestial Hemisphere. Its name comes from the Latin word ""raven"" or ""crow"". It includes only 11 stars with brighter than 4.02 magnitudes. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations. The four brightest stars, Gamma, Delta, Epsilon, and Beta Corvi from a distinctive quadrilateral in the night sky. The young star Eta Corvi has been found to have two debris disks.
