Crab Nebula Info
The crab nebula is a part of the Taurus constellation and is a result of the supernova explosion. Astronomers believe that it formed due to the supernova explosion and the pulsar wind of the nebula within the constellation of Taurus. The nebula was first observed by John Bevis in 1731, and the findings also correspond to the findings of Chinese and Arab astronomers in 1054. |
The Crab nebula is considered to be the strongest and most persistent existence in the night skies. At the very middle of the crab nebula is the crab pulsar, which is a neutron star. Which means this is a spinning ball comprised if neutrons. They produce gamma and radio waves. The nebula radiates light to all the celestial bodies that surround it and that are how we are able to observe them.
The Earl of Rosse observed the nebula from Birr Castle in 1840 and he gave it the name crab nebula. He made a drawing of the galaxy by observing it and the end result looked like a crab. After that, in the 20th century, several photographs were taken of this galaxy and the pictures revealed that this galaxy was expanding. Because of the expansion of the nebula we can say that the nebula is now visible to earth, and has been since 900 years ago.
The Chinese and the Arabs recorded that a new star that is very bright and can also be seen in the day time. However, one of the possibilities is that they could have viewed only a guest star of this galaxy.
