Today’s Astronomical Events – August 1st, 2015

Delphinus, the Dolphin, trails behind the other summer constellations and appears barely ahead of the autumnal Pegasus and Aquarius. Relatively small and compact, it represents the dolphin sent by Poseidon, the god of the sea, to seek the beautiful nymph Amphitrite, whom the god had fallen in love with.

The constellation is home to several deep sky objects worthy of attention but many of those will be drowned by the light of the full Moon. One, however, is a very easy target for observers of all levels – if you can first find the constellation against the brightened background sky. Gamma Delphini is a well-known double star, easily split with a small telescope at low power. With just 35x, you’ll see a pair of very pale yellow-white stars of equal brightness huddled close together in the eyepiece.
