This week @AstronomyCast will discuss about the other end of the electromagnetic spectrum and explore the longer radio waves which are now accessible.

Apr 26th: The New Colors of Gamma Rays – Getting Shorter
The Earth’s atmosphere protects us from a Universe that is definitely trying to kill us. But it also blocks our view of the entire cosmos, like seeing X-rays and gamma radiation. Space telescopes are changing our view of the most extreme events in the Universe.
Apr 19th: Unexpected Light Pollution
Right now, one third of humanity lives in so much light pollution that they can’t see the Milky Way without a drive. And now satellite constellations are adding additional light pollution, even in the darkest skies on Earth.
Apr 12th: Astronomy With The Unaided Eye
We talk a lot about telescopes, but you really don’t need any special equipment to appreciate what the night sky has to offer. Let’s talk about what kinds of things you can see with just your eyes.
Apr 5th: Calendars
Our lives are ruled by calendars. And calendars are ruled by astronomy. Let’s discover the astronomy underlying the days, weeks, months and years that segment our lives.
Mar 29th: Looking Ahead
Today we are gonna gaze into the future of space and astronomy. What upcoming missions & events are we excited about?
Mar 22nd: Zodiacal Light
Pamela has told us in the most flowery terms about the diffuse dust across the inner solar system left over from the formation of the inner planets. well, it turns out she was wrong. Super wrong. Time to update!
Mar 15th: How You Could Overturn Cosmology
You’ve probably heard of dark matter and dark energy, but maybe you don’t fully understand what they are. Or maybe the idea itself just rubs you the wrong way and you’d like to know why scientists think they can just make stuff up like this. So you’d like to overturn cosmology? Here’s all you need to do.
Mar 8th: The Expansion of the Universe
It’s been a while since we checked to make sure the Universe was still expanding. Yeah, apparently, that’s still a thing. But in the last few years powerful new telescopes and expansive surveys have given us much more knowledge about what’s happening. Especially at the earliest times.
Mar 1st: The Universe’s Background Noise
You might be familiar with the cosmic microwave background, but that’s just one of the background radiations that astronomers look at. Some are well known and cataloged. While others are just starting to be possible to see at all. All of them tell us more about our Universe.
