Auroras are occurring with increasing frequency now that solar activity is “heating up” after a dormant period. Check out this time lapse of Aurora Borealis in the Norwegian skies. No chance of seeing The Northern Lights down here in Florida, although I did see them once at Clarkson. I could hardly believe my eyes.
The first image below is of Saturn’s 2nd largest moon, Rhea, along with smaller moon Epimethius, against a backdrop of rings. Cassini has detected oxygen in Rhea’s extremely thin atmosphere.
