User rating: not rated yet
A University of California, Berkeley, astronomer has turned the NASAHubble Space Telescope on the brightest and nearest supernova of the past decade, capturing a massive stellar explosion blazing with the light of 200 million suns. The supernova, called SN 2004dj, is so bright in the Hubble image that it easily could be mistaken for a foreground star in our Milky Way Galaxy. Yet it lies 11 million light-years from Earth in the outskirts of a galaxy called NGC 2403, nestled in a cluster of mostly massive bright blue stars only 14 million years old.
