NGC 3982 [SEP] constellation
NGC 3982
NGC 3982 is an intermediate spiral galaxy approximately 68 million light-years away in the constellation Ursa Major. It is also known as UGC 6918. It was discovered by William Herschel on April 14, 1789 and misclassified as planetary nebula. NGC 3982 is a part of the M109 Group.
At an apparent magnitude of 12.0, NGC 3982 needs a telescope to be viewed. Using small telescopes, the galaxy appears as a very faint, diffuse patch of light with its central region appearing as a slightly brighter
the star detonated in a violent and extremely bright explosion. Since a supernova explosion roughly occurs in a typical spiral galaxy every 100 years, astronomers use high-resolution images of NGC 3982 and other galaxies to detect stars which are nearing a similar explosive descent into supernovae.
