Supernova star explosion
Friday, July 29, 2005

Hubble took this picture of the Supernova 2005cs 12 days after its discovery earlier this month. The Supernova is in the Whirlpool Galaxy also known as M-51. The little green box in the larger image is where the Supernova is. The two smaller images show the difference in the stars before and after the blast.

The star that exploded was a red supergiant with a mass of 7 to 10 times of our Sun; on the low end of the mass range of this type of explosion. The Supernova belongs to a class of exploding stars called a “Type II-plateau”. This type results from the collapse and subsequent explosion of a massive star whose light remains at a constant brightness for a period of time.
