Ep. 726: Looking Back Over The Summer

365 Days of Astronomy - Weekly Edition ·

2024/09/16

Streamed live Sep 9, 2024. We made all sorts of predictions, and some of the stuff we didn't know about last July, somehow, we still don't know about as we set up this episode on September 3! Join us for the first episode of Season 18 as we review all the crazy space science that happened during our Summer Hiatus.

Ep. 722: Weather on Exoplanets

365 Days of Astronomy - Weekly Edition ·

2024/06/10

Here’s a familiar question: How’s the weather? We’re familiar with the weather on Earth and telescopes and missions are watching the weather on other planets in the Solar System. But for the first time in history, astronomers can now answer that question for exoplanets, located light-years away from us.

Ep. 721: Rogue Planets

365 Days of Astronomy - Weekly Edition ·

2024/05/27

Most of the exoplanets we’ve found are around stars, where they belong. But a few have been found free-floating in interstellar space. The evidence is growing that there are a lot of them out there, maybe even more than planets with stars. How do they form and how can we learn more about them?

365 Days of Astronomy - Weekly Edition ·

2024/04/29

How old is that star? That planet? That nebula? Figuring out the ages of astronomical objects is surprisingly challenging. Fortunately, astronomers have developed a series of techniques they can use to work out the ages of stuff.

Ep. 716 - The God**** Particle - Remembering Peter Higgs

365 Days of Astronomy - Weekly Edition ·

2024/04/22

Last week, we learned about the death of Peter Higgs, a physicist and discoverer of the particle that bears his name. The Large Hadron Collider was built to find and describe the particle. Today, we’ll look back at the life of Peter Higgs and his particle.

Ep. 715: Total Eclipse of the Science: Experiments...

365 Days of Astronomy - Weekly Edition ·

2024/04/08

How to watch a solar eclipse and do some science! The next great eclipse is upon us, with viewers across North America witnessing the moon passing in front of the Sun. It’s an amazing experience, but also an opportunity to do science. Let’s talk about what we can learn from this momentous event.

Ep. 712: How Peer Review Fails

365 Days of Astronomy - Weekly Edition ·

2024/03/18

You’ve probably heard that the best kind of science is peer-reviewed research published in a prestigious journal. But peer review has problems of its own. We’ll talk about that today.

Ep. 709: Space Weapons

365 Days of Astronomy - Weekly Edition ·

2024/02/26

Streamed live on Feb 19, 2024. [My apologies for Fraser’s audio dropouts. We’re not sure how it happened as it wasn’t happening at his studio. Audio is a black art, IMHO. Rich) Last week we learned that Russia might be planning nuclear weapons to take out satellites in space. What is the current and future possibility of weapons in space and what are the treaties designed to prevent them?

365 Days of Astronomy - Weekly Edition ·

2024/02/19

Last week we talked about sample return missions from the Moon and Mars, but scientists have retrieved samples from other objects in the Solar System, including comets and asteroids. What does it take to return a piece of rock from space, and what have we learned so far?

Ep. 707: What Goes Into A Sample Return Mission? Moon...

365 Days of Astronomy - Weekly Edition ·

2024/02/12

We’ve sent robots to other worlds, but the amount of science we can deploy to another planet can’t compare with the vast science labs we have on Earth. That’s why more and more missions are for a sample return, bringing pieces of alien worlds back to Earth, where we study them with proper equipment.

Ep. 706: China’s Space Program

365 Days of Astronomy - Weekly Edition ·

2024/02/05

We’re so familiar with NASA’s exploration efforts in space, but you might be surprised to learn that China launches almost as many rockets as the US. They’ve got their own space exploration program that could soon bring humans to the surface of the Moon. Let’s give a brief overview of China’s space exploration plans.

Ep. 705: Water Worlds - Looking For Life Beyond Earth

365 Days of Astronomy - Weekly Edition ·

2024/01/22

Wherever we find liquid water on Earth, we find life, so it makes sense to search for water across the Universe, and hopefully we can find evidence of life. But what about worlds which are completely covered in water, oceans hundreds of kilometers deep. Can there be too much water?

Ep. 704: NASA's Juno Releases New Images

365 Days of Astronomy - Weekly Edition ·

2024/01/15

NASA’s Juno spacecraft has completed dozens of flybys of Jupiter, seeing the planet from many angles and delivering some of the most beautiful images we’ve ever seen of the Jovian world. Now it’s focusing in on Io, sending home images of the tiny volcanic world from just 1,500 km away. And the best is yet to come.

Ep. 703: Solar Maximum of Doom? Maybe

365 Days of Astronomy - Weekly Edition ·

2024/01/08

Streamed live on Dec 20, 2023. Solar cycle 25 is shaping up to be a doozy, with plenty of flares and coronal mass ejections blasting off the Sun. As the solar activity continues to rise, how are things shaping up?

Ep. 702: Moonshot 2024 - Go or No Go?

365 Days of Astronomy - Weekly Edition ·

2023/12/18

Streamed live on Dec 11, 2023. With Artemis 1 completing its robotic flight around the Moon, we know that the SLS works. Next comes Artemis 2, with a crew of astronauts flying past the Moon. If that’s successful, we could see humans set foot on the Moon in December 2025. But there is a long list of challenges to consider that could delay things considerably. Go or no go for launch‽

365 Days of Astronomy - Weekly Edition ·

2023/12/11

Last week we looked back at some of the ideas that science has changed its mind about. This week we look forward, into the future, at some of the big ideas that astronomers are making progress in. What space science are we looking forward to?

Ep. 700: The Things We Got Wrong

365 Days of Astronomy - Weekly Edition ·

2023/12/04

Astronomers talk about all the amazing discoveries they’re making but sometimes, it turns out, they were wrong. After decades and centuries of discoveries, how have they changed their minds?
