About Simeis 147

Simeis 147 is a supernova remnant located in the constellation Taurus. It is estimated to be about 3,000 light-years away from Earth and is believed to be the result of a supernova explosion that occurred around 40,000 years ago.

Although large, the nebula is extremely faint and therefore difficult to image. The photo above took well over 20 hours of exposure!

The nebula is believed to be home to a pulsar, a rapidly spinning neutron star that emits beams of radiation that can be observed from Earth.

Studies of Simeis 147 have provided important insights into the processes of supernova explosions and the evolution of stars.
