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
Columba (constellation) from Earth. Columba is the constellation at the solar antapex - the Earth (and Sun) is moving away from its direction as the solar system moves through space. The constellation contains the runaway star μ Columbae, which was probably expelled from the ι Orionis system. Exoplanet NGTS-1b and its star NGTS-1 are in Columba. There is one globular cluster in Columba, 7th-magnitude NGC 1851. It is 39,000 light-years from Earth and is resolvable in medium-sized amateur telescopes.<br> NGC 1792 is a spiral galaxy of magnitude 10.2. NGC 1808 is a Seyfert galaxy of magnitude 10.8.
