Worried about when Betelgeuse will go supernova? Worry no more.
There's a new light in the night sky. Around 12 million years ago, a star exploded in the galaxy M82. The light reached earth today. [more inside]
The cosmos is also within us, we're made of star-stuff. We are a way for the cosmos, to know itself.

Back in January, Dr. Megan Argo and an international team working at Jodrell Bank detected a powerful jet of energy from supernova 2007gr. Her way of announcing it? Doctor Who fan fiction describing the event from a TARDIS eye view. [via]
New burst vaporizes cosmic distance record. "NASA's Swift satellite and an international team of astronomers have found a gamma-ray burst from a star that died when the universe was only 630 million years old, or less than five percent of its present age. The event, dubbed GRB 090423, is the most distant cosmic explosion ever seen."
“Here was an object brand new. At first we didn’t recognize it.” Dr. Alicia Soderberg on the discovery of Supernova 2008D, using the Swift satellite telescope....
Life (Briefly) Near a Supernova (pdf, Google cache) by Steven Dutch (UW-Green Bay). What might it be like on a planet orbiting a star that went supernova? "It would take on the order of 100,000 seconds, or about a day, to receive enough energy to vaporize the Earth." Yes, Arthur C. Clarke and Larry Niven are name-checked. (And yes, the Sun is too small to actually go supernova, killjoy.) Via the nonist.
Odd Supernova Amateur and professional astronomers rejoice , point your telescopes at RA: 03:21:39.71 Dec: +16:52:02.6 to watch a new phenomenon that could turn into a supernova explosion
Instant Suntan. A supernova in our galactic backyard may be on the verge of exploding. In the (unlikely) event that it happens tomorrow, how would you spend your last day on earth?
