Astronomy Cast Ep. 604: Balloon Astronomy by Fraser Cain & Dr. Pamela Gay So when you think about the world's observatories, I'm sure you're imagining huge telescopes perched atop mountain peaks or space telescopes like Hubble. But you might be surprised to learn that some telescopes are carried high into the atmosphere on board balloons. What can they accomplish?
Ep. 603: New Colors of the Radio Spectrum
2021/05/03
Astronomy Cast Ep. 603: New Colors of the Radio Spectrum by Fraser Cain & Dr. Pamela Gay Last week we talked about how new telescopes and techniques are allowing astronomers to explore the shortest wavelengths of light. This week we go to the other end of the electromagnetic spectrum and explore the longer radio waves which are now accessible to astronome
Ep. 602: The New Colors of Gamma Rays - Getting Shorter
2021/04/26
Astronomy Cast Ep. 602: The New Colors of Gamma Rays - Getting Shorter by Fraser Cain & Dr. Pamela Gay 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.
Ep. 601: Unexpected Light Pollution
2021/04/19
Astronomy Cast Ep. 601: Unexpected Light Pollution by Fraser Cain & Dr. Pamela Gay Day-by-day we're loosing our connection with the night sky. Already 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.
