Ep. 604: Balloon Astronomy

365 Days of Astronomy - Weekly Edition ·

2021/05/10

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

365 Days of Astronomy - Weekly Edition ·

2021/05/03

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 astronomers.

Ep. 602: The New Colors of Gamma Rays - Getting Shorter

365 Days of Astronomy - Weekly Edition ·

2021/04/26

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

365 Days of Astronomy - Weekly Edition ·

2021/04/19

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.

Ep. 599: Zodiacal Light

365 Days of Astronomy - Weekly Edition ·

2021/03/22

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!

Ep. 598: How You Could Overturn Cosmology

365 Days of Astronomy - Weekly Edition ·

2021/03/15

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

365 Days of Astronomy - Weekly Edition ·

2021/03/08

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.

Ep. 596: The Universe’s Background Noise

365 Days of Astronomy - Weekly Edition ·

2021/03/01

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.

Ep. 595: Planet Hunting - Revisited

365 Days of Astronomy - Weekly Edition ·

2021/02/15

This is gonna be another one of those evergreen topics where we come back 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

365 Days of Astronomy - Weekly Edition ·

2021/02/08

Pamela is always loath 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! [Ed. Juno what I mean?]

Ep. 593: Stellar Parasites

365 Days of Astronomy - Weekly Edition ·

2021/02/01

Stars often come in groups of 2 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

365 Days of Astronomy - Weekly Edition ·

2021/01/25

Some of the most powerful explosions in the Universe are gamma-ray bursts, capable of blasting a beam of death half way 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 originally thought. The old Gamma-Ray bursts show: http://www.astronomycast.com/2007/05/episode-36-gamma-ray-bursts/

Ep. 591: What Are We Gonna Do With All That Space Junk?

365 Days of Astronomy - Weekly Edition ·

2021/01/18

Remember the good old days when there were only a few thousand living and dead satellites? Well, those days are long over. We're now entering an era where there will be tens of thousands of satellites. Not to mention the spent rocket boosters and other space junk. What kind of risk do we face and what can be done about it?

Ep. 590: Lunar Hazards: Dust, Radiation and More

365 Days of Astronomy - Weekly Edition ·

2021/01/11

2024 can't come soon enough. You know, that's the year when humans will set foot on the Moon again. Now don't you roll your eyes! That's the plan. Unless the plan changes. But my point is, explorers going to the Moon will need to be concerned about all kinds of hazards, like dust, radiation and gigantic Moon worms. I believe.

Ep. 588 - Lunar Resources: Lava Tubes

365 Days of Astronomy - Weekly Edition ·

2020/12/14

All eyes are on the Moon. We're going back, this time to stay, right? One of the best resources on the Moon will be the lava tubes that criss-cross the subsurface of the Moon. These can provide protection from space, and a look at the geologic history of the Moon, and they can be enormous!
