September Stargazing

Time is flying by! So is the Earth. Keep looking up!

Stargazing Summary
For much of the country, September is a perfect time for some evening skywatching. The nights are longer and cooler but not yet frigid, and there's plenty to look at. The Summer Triangle remains in good view high in the sky, while Scorpius and Sagittarius wheel across the southwest. In the east, Pegasus, Andromeda, and Perseus climb into view after sunset.

September 10-16: Quaking Moon. Quakes large and small rattle the Moon, and we'll tell you why. We'll also explain why Jupiter is the "speediest" planet in the solar system, and more. Join us for the Moon, Jupiter, and much more.

September 17-23: Symbiotes. A pair of stars in Andromeda has an unusually close relationship, and we'll have details. We'll also talk about the first successful trip to the Moon and back, a season with a double identity, and more.

September 24-30: Atoms for peace. A pair of colliding galaxies looks like a diagram of an atom, with electrons orbiting a nucleus. That led to the pair's nickname: the Atoms for Peace galaxies. Join us for this, plus another galactic smash-up and more.
