Surprising #Comet ISON

#Comet Leonard's Long Tail

Comet Leonard's tail was too long for telescopes and too dim for the naked eye. Only cameras in dark, low-horizon locations could capture it. The featured image was taken from La Palma, Spain. If it survives its close Sun encounter today, the comet will exit our Solar System forever.
