Ep. 138: Quantum Mechanics
Are new stars dark until their photons reach the surface? How fast do neutrinos travel? And what’s the story with Hawking Radiation? If you've got a question for the Astronomy Cast team, please email it in to info@astronomycast.com and we'll try to tackle it for a future show. Please include your location and a way to pronounce your name.
Questions Show: Hidden Fusion, the Speed of Neutrinos, and Hawking Radiation
This week we’re going to think big. Bigger than big. We’re going to consider the biggest things in the Universe. If you could pull way back, and examine regions of space billions of light-years across, what would you see? How is the Universe arranged at the largest scale? And more importantly… why?
Ep. 137: Large Scale Structure of the Universe
How do planets get their atmospheres? What would happen to the Earth if the Moon just disappeared? And what’s that strange glow we see after sunset? If you've got a question for the Astronomy Cast team, please email it in to info@astronomycast.com and we'll try to tackle it for a future show. Please include your location and a way to pronounce your name.
Questions Show: The Source of Atmospheres, the Vanishing Moon, and a Glow After Sunset
And now we reach the end of our tour through the electromagnetic spectrum. Last stop: gamma rays. These are the most energetic photons in the Universe, boosted up to incredible energies in the most violent places in the Universe. Gamma rays are tricky to catch, but they can reveal the most dramatic events in the Universe.
Ep. 136: Gamma Ray Astronomy
Can our Sun generate a solar flare that would wipe out life on Earth? Has the Large Hadron Collider answered any questions about the Higgs boson? And what would happen if you shined your flashlight out the front window of a spaceship going almost the speed of light? If you've got a question for the Astronomy Cast team, please email it in to info@astronomycast.com and we'll try to tackle it for a future show. Please include your location and a way to pronounce your name.
Questions Show: Dangerous Solar Flares, Higgs Boson Insights, and Light Speed Flashlights
If you've ever broken a bone, X-rays are a part of the electromagnetic spectrum. Doctors use X-rays to study the human body, and astronomers use X-rays to study some of the hottest places in the Universe. So let's put on our X-ray specs, and see what we can see.
Ep. 135: X-Ray Astronomy
Pamela was lucky enough to attend the NorthEast Astronomy Forum, and while she was there she held a live questions show. And now you get to join in an hear the interesting questions, and Pamela's interesting answers.
