This Week's Sky at a Glance, January 22 – 30
Right after dark, face east and look very high. The bright star there is Capella, the Goat Star. To the right of it, by a couple of finger-widths at arm's length, is a small, narrow triangle of 3rd- and 4th-magnitude stars known as "the Kids." Though they're not exactly eye-grabbing, they form a never-forgotten asterism with Capella.

This Week's Sky at a Glance, January 15 – 23
Bright Capella high overhead, and equally bright Rigel in Orion's foot, have almost the same right ascension. This means they cross your sky’s meridian at almost exactly the same time. So whenever Capella passes the zenith, Rigel marks true south, and vice versa. That happens around 9 or 10 p.m. now.
