Taurus (constellation) astronomers. Taurus hosts two of the nearest open clusters to Earth, the Pleiades and the Hyades, both of which are visible to the naked eye. At first magnitude, the red giant Aldebaran is the brightest star in the constellation. In the northwest part of Taurus is the supernova remnant Messier 1, more commonly known as the Crab Nebula. One of the closest regions of active star formation, the Taurus-Auriga complex, crosses into the northern part of the constellation. The variable star T Tauri is the prototype of a class of pre-main-sequence stars. Taurus is a big and prominent constellation in
Antinous (constellation) current finds include a celestial globe by the cartographer Caspar Vopel from 1536 that contains Antinous, so Brahe simply measured up the sky according to contemporary traditions and decided to give Antinous a separate table in his star catalogue. In the following modern times, Antinous has been variously considered an asterism within Aquila or as a separate constellation, until the International Astronomical Union discarded it when formalizing the constellations in 1930. Antinous (constellation) Antinous is an obsolete constellation no longer in use by astronomers, having been merged into Aquila, which it bordered to the North. The constellation was created by
