Hello and welcome to the 2020 How far Away Is It review. It’s been a terrible year for the globe, but Hubble and all the world’s telescopes continued to examine the sky and found a number of fascinating things. Close to home, we’ll see news on Saturn’s rings, storms on Jupiter, and a comet with two tails. A little further out we’ll see updates on the exoplanet Fomalhaut b, Betelgeuse dimming, a moving Bat Shadow, an interesting globular star cluster, and a fly-through the Orion Nebula. We’ll cover Wolf-Rayet stars, a fading planetary nebula, and a look at the age of stars in the Milky Way Central Bulge. Still further out, we’ll see some spectacular nebula around the Large Magellanic Cloud. We’ll see a few distant galaxies, a fading Supernova and an early galaxy as seen through gravitational lensing. We’ll end with a look at the new James Webb Space Telescope due for launch this year and a few of the astronomical areas it will investigate – dust and the first stars.
