Northern Sky: April 29 - May 12

Deane Morrison is a science writer at the University of Minnesota, where she authors the Minnesota Starwatch column.

May Day is also known as the witches' Sabbath. In the evening sky there are many constellations that can be seen through the summer. Venus is now only a morning star; brilliant Jupiter is seen at nightfall. Arcturus is part of a stream of stars thought to be remnants of a small galaxy, and May 10 is the full "flower" moon.
