Double Stars

Never underestimate the beauty of double stars. Often times brilliant bright stars in the night sky are actually binary star systems and with the proper eye training or even a low-costing pair of binoculars you’ll be able to see so for yourself.

Mizar — the star in the bend of the handle of the big dipper — is a classic example. With really good eyes you should be able to make out Mizar’s companion: Alcor. But with a small telescope you’ll see a third star forming a triangle with the first two, and finally yet another faint companion to Mizar.

Other pairs show contrasting color. Albireo is the gold and green pair, and Almach is the orange and blue pair. All double star systems have wonders to reveal. Check back here for latest tips on observing our favorite pairs.
