Have you ever seen a comet? Tonight -- and likely the next few nights -- should be a good chance. Go outside just at sunset and look to your northwest. The lower your horizon, the better.

The Terraced Night
6.02.2014

Long after sunset on January 25 an unusually intense red airglow floods this south-looking skyscape.
