Globe at Night is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure & submit their night sky brightness observations.
Orion looks very much like a person. First, you should spot Orion’s Belt, which is made of three bright stars in a straight line. One of Orion’s legs is represented by the bright star Rigel, one of the brightest stars in the night sky. His two shoulders are made of the stars Bellatrix and Betelgeuse. You can see Betelgeuse’s reddish color without a telescope.
Visible in: Northern hemisphere, Southern hemisphere
To find the constellation Canis Major, first locate the constellation Orion. The three stars that make up Orion's belt point southeast to Sirius, the brightest star in the night sky. Sirius is the neck of Canis Major. Slightly below and to the right of Sirius is the front paw, and other bright stars below and to the left mark the hindquarters including the tail and rear paw.
