The Herdsman
Featured on May 9, 2019
The constellation Bootes, the herdsman, climbs high across the sky on spring and summer nights. It is well up in the east at nightfall now, marked by its brightest star, Arcturus, which is one of the brightest stars in the night sky. Well to its left is Izar, a binary system whose two stars are separated by billions of miles.
