(MPL23183_060125), wait for the frost on the CCD window to evaporate!

FS Auriga Field

Star field with cataclysmic variable star FS Auriga and our newly discovered eclipsing binary (2007 AJ, 133, 1944,
2011 AJ, 141, 124). Try and find the cataclysmic variable, its accretion disk puts out lots of UV lightmaking it appear as an extremely blue star right of center.

Observations of a galaxy before and after one of its star's went supernova.The light from the supernova almost outshines the galaxy of several billion stars itself.
