This isn’t really Viz related, but I know we have a lot of science and astronomy geeks reading here, so I wanted to share this rare event!  Tonight will be a rare 72-minute long Lunar Eclipse!

The eclipse begins on Tuesday morning, Dec. 21st, at 1:33 am EST (Monday, Dec. 20th, at 10:33 pm PST). At that time, Earth’s shadow will appear as a dark-red bite at the edge of the lunar disk. It takes about an hour for the “bite” to expand and swallow the entire Moon. Totality commences at 02:41 am EST (11:41 pm PST) and lasts for 72 minutes.
