Ep. 601: Unexpected Light Pollution
Day by day, we’re losing our connection with the night sky. Already 1/3rd 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.
Ep. 600: Looking Ahead
Today, we gaze into the future of space and astronomy. What upcoming missions and events are we excited about?
Ep. 599: Zodiacal Light
Pamela has told us in the most flowery terms about the diffuse dust across inner solar system. Leftover from the formation the inner planets. Well, it turns out, she was wrong. Super wrong. Time to update.
Ep. 598: 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.
Ep. 597: The Expansion of the Universe (Updated)
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.
Ep. 596: Universe’s Background Noise
You might be familiar with the cosmic microwave background, but that’s just one of the background radiations astronomers look at. Some are well known and cataloged, while others are just starting to be possible to see. All of them tell us more about our Universe.
Ep. 595: Planet Hunting (Updated)
This is going to be another one of those evergreen topics, where we come back to again and again. Finding planets. Every time we talk about this now, it seems like we’ve gained thousands of new planets. Well buckle up, new techniques will grow that by tens of thousands and even millions.
Ep. 594: Juno – Primary Mission Highlights
Pamela’s always loathed to talk about spacecraft until the mission’s in space and the science is rolling. NASA’s Juno mission just received a mission extension, adding Jupiter’s moons to the menu. Now, finally, we can talk about Juno.
Ep. 593: Stellar Parasites
Stars often come in groups of two or more. And if they’re orbiting close enough to each other, one star can feast on the other. And when that happens, well, mayhem ensues.
Ep. 592: Gamma-Ray Bursts (Updated)
Some of the most powerful explosions in the Universe are gamma ray bursts, capable of blasting a beam of death halfway across the galaxy. In just the last few years, astronomers have discovered a tremendous amount about these blasts, and what’s actually causing them. The answer, of course, is that it’s more complicated than we thought.
