„The Supernova of a Lifetime“ and an old Planet made of Diamond

Derzeit beobachten Astronomen praktisch live eine Supernova, die „nur“ 21 Millionen Lichtjahre von der Erde entfernt stattfindet und die wir in den nächsten Wochen unter Umständen mit dem Fernglas selbst sehen können, was so bis jetzt nur vier mal überhaupt vorher stattfand (1986, 1972, 1937 und 1572). Oder anders gesagt: There's a champagne supernova in the sky, right now.

Astronomers believe they caught the supernova within hours of its explosion, a rare feat made possible with a specialized survey telescope and state-of-the-art computational tools. The finding of such a supernova so early and so close has energized the astronomical community as they are scrambling to observe it with as many telescopes as possible, including the Hubble Space Telescope.

“We caught this supernova very soon after explosion. PTF 11kly is getting brighter by the minute. It’s already 20 times brighter than it was yesterday,” said Peter Nugent, the senior scientist at Berkeley Lab who first spotted the supernova. Nugent is also an adjunct professor of astronomy at UC Berkeley. “Observing PTF 11kly unfold should be a wild ride. It is an instant cosmic classic.”
