Winter Skies
Orion,
the Hunter, is one of the most easily recognizable
constellations in planet Earth's night sky. Orion is a
great place to start your tour of the night sky. It
serves as an excellent guide to several bright stars.
The cool red giant Betelgeuse is the bright star at the
upper left. Otherwise The supergiant Rigel balancs
Betelgeuse at the lower right, Bellatrix is at the upper
right, and Saiph is at the lower left. Lined up in
Orion’s belt (left to right) are Alnitak, Alnilam, and
Mintaka all about 1,500 light-years away, born of the
constellation's well-studied interstellar clouds. And if
the middle "star" of Orion's sword looks reddish and
fuzzy to you, it should. It's the stellar nursery known
as the Great Nebula of Orion.
