In this week's Astronomy magazine podcast, we'll help you observe open cluster NGC 7790, the Cave Nebula, and spiral galaxy NGC 7184 in your September night sky.

The Crab Nebula is one of the brightest supernova remnants in the night sky.

Those include the California Nebula in the constellation Perseus, which is about 1,000 light-years from Earth, as well as the Cave Nebula in the constellation Cepheus, about 2,400 light-years away.

How can a team on Earth effectively explore intricate, dark, unfamiliar landscapes on another world? Fully autonomous robots.

To see the Crab Nebula for yourself, you'll have to wait until around midnight local daylight time, after it has sufficiently risen high enough above the east-northeast horizon.
