Supernova SN Wilson (UDS10Wil). Source
The Hubble space telescope, that amazing, floating telescope that has been providing us with beautiful images of the universe since 1990, has found something else wonderful and exciting to show us. This picture here is of the type 1a supernova UDS10Wil, nicknamed SN Wilson. SN Wilson is the farthest, and thus oldest, supernova ever seen by mankind. This is exciting to scientists for many reasons, not the least of which is that it will give us insights into the early years of the universe. SN Wilson is more than 10 billion (that's right, billion) years old, making it the nearest supernova to the beginning of the universe yet.
I recommend reading this article, it's very insightful.
