Astronomy Cast Ep. 616: Hangout-A-Thon Episode 1 - The Great Observatories

Well, you’re familiar with the Hubble Space Telescope of course, but it’s just one of NASA’s Great Observatories. After Hubble came 3 more incredible telescopes. Each greater than the last! (That’s not true… The first one was the greatest.) But together they would fill in almost the entire electromagnetic spectrum.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
