Constellation of the Month—Leo

Look for Leo high in the eastern sky. Leo's brightest star is blue-white Regulus, (α Leo) one of the brightest stars in the night sky . It rises almost due east, with the body of the lion following it into the sky over the next couple of hours.

About two hours later, look low in the east for Leo's tail — a white star named Denebola ( βLeo) — an Arabic name that, appropriately enough, means "tail of the lion."

Leo contains many bright galaxies of which Messier 65,66,95 and 96 are the most famous
