PICTURE OF THE DAY

Mizar (Zeta Ursae Majoris) and Alcor (80 Ursae Majoris) make up probably the sky’s most famous double star.

Mizar and Alcor

Mizar (Zeta Ursae Majoris) and Alcor (80 Ursae Majoris) make up probably the sky’s most famous double star. You can find them at the bend of the Big Dipper’s handle. Sharp-eyed observers can separate them with just their naked eyes. The two stars lie roughly 90 light-years from Earth.
