Love Astronomy Minute!
Astronomy Minute brings the fascinating, and often overwhelming, subjects of astronomy and astrophysics to the world in short, easily digested episodes. It’s an awesome (and fun!) way to learn something new, or brush up on previously explored topics in a short amount of time. It’s also great for homeschoolers as a jumping off point for further study. Highly recommend!
