The History Channel show on "The Universe" mentioned the hypernova SN 2006gy in the episode about stars. This SN facinated me: such a big explosion, such a big star!

An astronomer said it was probably a first generation star, because that's the only time stars were made that big. It also has hydrogen lines in it's supernova sperctra. Yet the star is 250 million ly away.

I thought stars that big only lived about 1 myrs, so how could it only be 250 mlys away?
