The Big Picture Hubble Advent Calendar

They fine folks at the Boston Globe are doing another Hubble Space Telescope Advent Calendar. It started yesterday will feature a different Hubble image each day until December 25th. Here is the first image

This is NGC 2818, a planetary nebula. It is star that ended its life and shed off its outer layers. Our Sun will end its life as a planetary nebula.

Be sure to check back each day for the new picture.
