The Insider's Guide to the Galaxy

(Formerly Homebound Astronomy)

Join us online to learn basic astronomy that you can do on your own from your backyard! We'll give you the tools to learn astronomy on your own at home, along with some observing goals to try. All you need is your computer! A pair of binoculars will help, but are not necessary. Sessions are always on Tuesdays at 3:30pm ET, but frequency of sessions changes. Please see below for details.

TIMING CHANGE: Over the summer we will be slowing down our streams a bit. We are taking a break for all of June, and will only hold one session per month in July and August. Come September, we will be back to every other Tuesday at 3:30pm ET!

Register here! Videos will also be livestreamed to The RASC YouTube Channel.

Life Cycles of the Stars

  • The stars are just like us! They're born, they get older (and bigger) and then they die. Some live fast and die young, others linger almost “forever”, and the most massive ones explode into supernovae, neutron stars, and black holes. Find out how to see stars at all different stages of their life, right from your own backyard.

Galaxies in Plain Sight

  • It's New Moon time! Usually to find galaxies you have to carefully study a star chart, point your telescope at the right patch of sky, and then try to see and focus on a fuzzy patch amid total blackness. But Chris has a trick up his sleeve! He’ll be helping us easily find galaxies using nextdoor-neighbour stars that guide us right to them. Bring a notebook; you’ll want to go out observing right after this session!
