The nights of July are short, but they are packed with sky happenings and objects. All five naked-eye planets are visible at some point during the month, with Venus ending its long run as the morning star. It is barely visible in early twilight at July's start, then disappears by the middle of the month.
The “dog days” of summer are upon us. They get their name from the Dog Star, Sirius. The brightest star in the night sky, it is immersed in the Sun’s glare at this time of year. Because of that, ancient skywatchers named this period in the star’s honor.
The Moon is full at 1:40 a.m. CDT today. The full Moon of July is known by several names, including Hay Moon and Thunder Moon. Since the first people landed on the Moon during the month of July, we might someday add “Apollo Moon” to the list.
The evening skies of summer feature Aquila, the Eagle, whose brightest star, Altair, is easy to see. But the constellation also hosts one of the faintest stars yet discovered. Known as Van 17, 2011
