As we prepare to say goodbye to Cassini at Saturn - one of the longest-running and most awesome space missions ever - here's yet another first, a finely seen section of Saturn's inner-central B Ring, in natural color.
Space weather forecasters predicted the possibility of strong geomagnetic storms, resulting in a strong display of the aurora borealis, or northern lights … and they were right!
This large asteroid swept closest to Earth on September 1. It's big enough that astronomers are still catching it in small telescopes, as a small, slow-moving “star.”
Sunwatchers are still tracking those 2 large sunspot groups making their way across the Earth-facing side of the sun. Then yesterday there was an X-flare! Watch for possible auroras.
The start of September means that autumn is just around the corner. Manish Mamtani took this shot in September 2016 in Grand Teton National Park in Wyoming.
