Photos: Green comet captured by digital camera

Comet Lovejoy reached its closest approach to the sun on March 27 and will become visible in the Northern Hemisphere next week. Unfortunately, it won't be visible to the naked eye, but it can probably be seen with binoculars or a small telescope. Here's where to look.

The comet's green color is probably due to cyanogens and diatomic carbon.

Shown here is another photo of Comet Lovejoy from the Possum Observatory.
