Struve 559 -- Double Star in Taurus
Eyes Above Aldebaran
Aldebaran (red eye of the bull) shines as a bright star in the winter sky. It is a nighttime signpost
and one of the first stars learned by beginning amateur astronomers. Nearby, just over a degree
northwest of the bull’s eye, is another pair of far dimmer eyes. I have always fancied double
stars that are equal in brightness and color. They remind me of eyes in the blackest of forests.
Struve 559 is such a double star.
