As the bright planets march westward, Uranus and Neptune become the fresh new faces of fall. And if you've never seen an ultra-thin lunar crescent, here's your chance.
The planets are aligning! The week ahead will feature multiple planetary conjunctions at dawn and great views of Neptune and Triton at nightfall.
Now you see 'em, now you don't. Watch the Moon occult Neptune and nearby Lambda Aquarii on the same night.
