The Skies Of Fall
Just after sunset if you look directly overhead you will see the summer triangle, an astrism, which is made up the the brighest stars of three constellations: Altair (in Aquilla), Deneb (in Cygnus), and Vega (in Lyra). The circumpolar constellations of Ursa Major (big bear) and Ursa minor (little bear) whatch over our adirondack nights. You may be more familiar with Ursa Major and Minor as the Big and Little Dipper. Officially the Big and Little Dipper are astrisms, not constellations. There are 88 official constellations, which were decided upon by the International Astronomical Union.
