In this 2018 review we’ll see the northern lights on Saturn: a new asteroid landing close to Earth; the ghost of Cassiopeia; new information on the stars at the center of our galaxy; and more. We’ll also cover the second GAIA data release on 1.7 billion stars. We’ll then go beyond the galaxy to see a wide variety of galaxies and galaxy clusters. We’ll see a single star 9 billion light years away.

Our deep dive this year is a close look at Brown Dwarfs: what are they; how do they form; and where do they fit between high mass planets and low mass stars; and we’ll take a look at a few of them.
