Facts About the Bull
The constellation Taurus is hard to miss as he charges through the northern winter sky. "The bull" is one of the most noticeable constellations and one of the oldest documented constellations, with descriptions of Taurus going as far back as the early Bronze Age. Taurus is most famous for its red giant star, Aldebaran, as well as a star cluster known as the Pleiades.

Notable Stars and Objects
The red giant star Aldebaran is 65 light-years from Earth. It is the brightest star in the constellation and the 14th brightest star in the sky, according to EarthSky.org. Aldebaran also forms part of a V-shaped asterism, or group of stars, that is called the Hyades; this shape makes up the bull's face. Orange-hued Aldebaran is often described as glaring at Orion, the hunter, a constellation that lies just to the star's southwest. The planetary probe Pioneer 10 is moving in the general direction of that star, expected to make its closest pass by Aldebaran in roughly 2 million years, according to NASA.
In addition to the Hyades, the constellation's other major star cluster is the Pleiades, which consists of seven stars that rest on the bull's shoulder. It is said that these stars represent the Seven Sisters, daughters of Atlas and Pleione from Greek mythology. NASA's Kepler space telescope examined the Pleiades. In results released in 2017, astronomers found that six of the seven stars are variable B stars that change brightness over the course of a day. The Pleiades are visible to the naked eye, although the number of stars seen varies depending on your eyesight and the local conditions.
In the northwest part of Taurus is the supernova remnant Messier 1, commonly referred to as the Crab Nebula. It is located above the tip of the bull's bottom horn. In 2018, NASA released a video tour of this nebula based on data from the Chandra X-Ray Observatory, Hubble Space Telescope and Spitzer Space Telescope.
Mythology
The bull is a representation of Zeus in Greek mythology. Zeus shapeshifted into a bull when he wanted to seduce Europa, the daughter of king Agenor or Phoenicia. As a bull he stood in the middle of the herd of the king. Obviously, Zeus was the most handsome bull, so he managed to get Europa’s attention. Europa decided to sit on its backs, at which point the bull rose and ran off. Once they got to Crete, it was time for Zeus to change back into his own self and tell Europa who he really was. He handed her tons of presents in order to keep her happy. The presents seem to have worked, because in the end they ended up having 3 sons. The most famous one being Minos. Minos ended up to become the king of Crete and he built a palace at Knossos where bull games were held every year. Zeus, being happy with the results, decided to promote the bull to a constellation by placing it amongst the stars in the sky.
