Supernova Survivor (Feb 12 2004)  Credit: Justyn R. Maund (IoA/Univ. Cambridge) et al., ESA   Inset Left: Isaac Newton Telescope, Bottom: Hubble WFPC2, Right: Hubble ACS Beginning with a full view of beautiful spiral galaxy M81, follow the insets (left, bottom, then right) to zoom in on a real survivor. Seen at the center of the final field on the right is a star recently identified as the survivor of a cosmic cataclysm -- the supernova explosion of its companion star. #astronomy

A Supernova in Nearby Galaxy NGC 2403 (Sept 7 2004)  Credit: A. V. Filippenko (UC Berkeley), P. Challis (Harvard CfA), et al., ESA, NASA The closest and brightest supernova in over a decade was recorded just over a month ago in the outskirts of nearby galaxy NGC 2403. Officially tagged SN 2004dj, the Type IIP explosion likely annihilated most of a blue supergiant star as central fusion could no longer hold it up. #astronomy

Death Star: Eta Carinae, one of the closest stars to Earth is huge and unstable and will likely explode in a supernova in the relatively near future (On an astronomical timeline this could be a million years from now). via NASA

A Nearby Supernova in Spiral Galaxy M100 (Mar 7 2006)  Credit: FORS Team, 8.2-meter VLT, ESO One of the nearer supernovas of recent years was discovered last month in the bright nearby galaxy M100. The supernova, dubbed SN 2006X, is still near its maximum brightness and visible with a telescope toward the constellation of Berenice's Hair (Coma Berenices) #astronomy

A Young Supernova in the Nearby Pinwheel Galaxy (Aug 26 2011)  Image Credit: D. Andrew Howell & BJ Fulton (LCOGT) et al., Faulkes Telescope North, LCOGT A nearby star has exploded and telescopes all over the world are turning to monitor it. The supernova, dubbed PTF 11kly, was discovered by computer only two days ago as part of the Palomar Transient Factory (PTF) sky survey utilizing the wide angle 1.2-meter Samuel Oschin Telescope in California. #astronomy

Light Echoes from V838 Mon (Dec 4 2011)  Image Credit : NASA, ESA, H. E. Bond (STScI) For reasons unknown, star V838 Mon's outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded. A stellar flash like this had never been seen before. It's true that supernovae and novae expel matter out into space. But while the V838 Mon flash appears to expel material into space (...) #astronomy
