Aries the Ram is a small constellation, but has a special significance in the night sky because of the way the celestial coordinate system is set up.  But!  Those coordinates have shifted over time - find out how the "Zero Hour" of right ascension is calculated, how you can find it, and what Aries has to do with it - along with a few great double stars to see in the constellation as well.  Mercury remains visible near Venus and Saturn in the morning sky, while Mars hangs low in the southwestern morning sky, and Jupiter largely rules the entire night, not far from Aries.  See what's up in the night sky every week with "Eyes on the Sky" videos, astronomy made easy.
