Ep. 136: Gamma Ray Astronomy
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.
Questions Show: Dangerous Solar Flares, Higgs Boson Insights, and Light Speed Flashlights
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?

Ep. 135: X-Ray Astronomy
We continue our journey through the electromagnetic spectrum with X-rays. If you’ve ever broken a bone, you probably know how X-rays are most commonly used. While 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.
