Delta Lyrae, which is about halfway up the eastern sky at nightfall, consists of two stars, one blue and one red. The colors indicate that the stars have different surface temperatures. The blue star is hot, while the red star is cool.

June 25: Delta Lyrae
June 26: Renegade Stars
The stars at opposite ends of the Big Dipper are described as renegades. While the dipper’s other stars move through the galaxy together, the stars at the ends go their own ways. In 50,000 years, that will destroy the dipper’s shape.
June 27: Sagittarius
Sagittarius, the constellation that marks the center of the Milky Way galaxy, scoots low across the south on summer nights. Its brightest stars form the outline of a teapot, with the glowing band of the Milky Way rising from the spout like steam.
June 28: Ara
Below the curved tail of Scorpius, deep in southern skies, Ara, the altar, sends its tendrils of smoke billowing into the Milky Way. Although faint, Ara has a long history. It probably originated in Sumeria about 5,500 years ago.
June 29: Evening Zodiac
Half of the constellations of the zodiac line up across the south as night falls this evening. They stretch from Cancer, which is quite low in the west, to Leo, Virgo, Libra, Scorpius, and finally Sagittarius low in the southeast.
June 30: Eagle Nebula
One of the most beautiful and inspiring regions in the galaxy, the Eagle Nebula, climbs across the south on summer nights. Binoculars reveal some of its stars, and a telescope shows its hazy outline.
