Next time you see the Big Dipper out of the corner of your eye, take a look at the star in the middle of the handle. If you have decent eyesight, you may see not one, but two stars: a brighter star known as Mizar, and a fainter star called Alcor.
The Big Dipper is a great starting point for learning the night sky. Located near the pole of the sky, it never completely sets or dips below the horizon—it’s visible in the night sky year-round from the Western Slope!
The Big Dipper itself is not a constellation, but it resides in one called Ursa Major, the Great Bear, third largest of the 88 constellations. The name originates from the dipper-shaped pattern formed by the seven main stars in the constellation.
