Mars, Jupiter, Saturn, Uranus, AND Neptune will all be in the evening sky this weekend. And so will Pluto, if you still consider it to be a planet, but most amateur telescopes won't have a chance of spotting it.
The Alpha Persei (PER-see-EYE) Cluster is an open cluster of hot, bluish-white B-type stars. These kinds of stars are so energetic, they don't live long. So most of the B-type stars we can see in the night sky are, on the cosmic scale, practically newborns.
