A team of astronomers at The Johns Hopkins University has used data gathered by NASA’s Hubble Space Telescope to spot a supernova that exploded more than 10 billion years ago, breaking the previous record by roughly 350 million years. Nicknamed in a nod to Woodrow Wilson, the 28th president of the United States and a Johns Hopkins alumnus, “SN Wilson” now stands as the farthest known supernova of the type used to measure cosmic distances.

A team of Johns Hopkins astrophysicists using NASA’s Hubble Space Telescope has detected a distant Type Ia supernova, the farthest stellar explosion that can be used to measure the expansion rate of the universe. The supernova is the remnant of a star that exploded 9 billion years ago.
Adam Riess, an astrophysicist at The Johns Hopkins University and the Space Telescope Science Institute, today was awarded the Einstein Medal 2011 by the Albert Einstein Society of Bern, Switzerland. The society board of trustees recognized Riess for leadership in the High-z Supernova Search Team’s 1998 discovery that the expansion rate of the universe is accelerating, a phenomenon widely attributed to a mysterious, unexplained “dark energy” filling the universe. Riess, 41, shares this year’s prize with Saul Perlmutter, an astrophysicist at the University of California, Berkeley and the Lawrence Berkeley Laboratory, whose Supernova Cosmology Project team published similar results shortly after those published by Riess and High-z teammate Brian Schmidt, of the Australian National University.
