A Yellow Super Giant Has Exploded

All was quiet in the Whirlpool Galaxy….. until suddenly the core collapsed of a yellow supergiant star called SN 2011dh and the star exploded .

This was observed one week ago and we have included the pictures of the galaxy below .

The left hand image shows the Whirlpool Galaxy before the star exploded as a supernova. The middle image shows the supernova in progress and the right hand image points to the supernova itself.

Interestingly this is the third supernova like this seen in the Whirlpool galaxy in 17 years…… 2011,  2005  and 1994
