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
Auriga (constellation) Aurigae (Menkalinan, Menkarlina) is a bright A2IV class star (A-type subgiant). Its Arabic name comes from the phrase "mankib dhu al-'inan", meaning "shoulder of the charioteer" and is a reference to Beta Aurigae's location in the constellation. Menkalinan is 81 light-years away and has a magnitude of 1.90. Like Epsilon Aurigae, it is an eclipsing binary star that varies in magnitude by 0.1. The two components are blue-white stars that have a period of 3.96 days. Its double nature was revealed spectroscopically in 1890 by Antonia Maury, making it the second spectroscopic binary discovered, and its variable nature was discovered
