Supernova Sonata by Alex Parker
From April, 2003 until August, 2006, the Canada-France-Hawaii Telescope
watched four parts of the sky as often as possible. Armed with the largest digital camera in the known universe, CFHT monitored these four fields for a special type of supernova
(called Type Ia) which are created by the thermonuclear detonation of one or more white-dwarf star
s. Each supernova is assigned a note to be played:
The volume of the note is determined by the distance to the supernova, with more distant supernova being quieter and fainter.
The pitch of the note was determined by the supernova’s “stretch,” a property of how the supernova brightens and fades. Higher stretch values played higher notes. The pitches were drawn from a Phrygian dominant scale
The instrument the note was played on was determined by the properties of the galaxy which hosted each supernova. Supernovae hosted by massive galaxies are played with a stand-up bass, while supernovae hosted by less massive galaxies are played with a grand piano.

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

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

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?
