The bright, green glow of a springtime comet shines in this amazing photo captured by an stargazer using the Mount Lemmon SkyCenter in Arizona.
The image of Comet C/2012 K1 PanSTARRS was sent in by Adam Block from The University of Arizona and taken on May 5.
"As it brightens over the next few months it should remain a nice object to watch in its journey across the sky," Block wrote in an email to Space.com. [Amazing Stargazing Photos of May 2014]
Comet C/2012 K1 PanSTARRS is a springtime comet that is expected to wax bright enough to possibly see with the naked eye. In April, it became bright enough to observe with a small telescope and it will make its closest approach to the sun near the end of August. C/2012 K1 PanSTARRS was discovered in 2012 by astronomers using the PanSTARRS telescope in Hawaii.
