Ep. 740: Sneaky Stars!

365 Days of Astronomy - Weekly Edition ·

2025/01/20

Streamed live on Jan 13, 2025. Why stars can’t be trusted! If you’re an astronomer you depend on accurate observations of stars, but there’s a problem. Stars are sneaky! Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode precisely when they intend to. Betelgeuse took a brightness plunge, T CrB refused to go nova, and other failures to be predictable irk observers for good reasons. Let's talk

Streamed live January 9, 2025. From little Ingenuity to the future Firefly and all our Earth Science fliers, let's look at the buzzy scientists. NASA’s Mars Ingenuity helicopter showed us how wonderful a flying science platform can be on another world. Soon there’ll be a helicopter flying on Titan, but there are many other flying robots that’ll be helping us with all our science needs.

Ep. 735: Albert Einstein

365 Days of Astronomy - Weekly Edition ·

2024/12/02

Streamed live on Nov 25, 2024. Last week we talked about the Einstein probe. So this week it is only natural that we talk about the man himself, Albert Einstein. He revolutionized the field of physics, played a vital role in the early 20th century and struggled to unite the forces of the Universe at the end of his career.

365 Days of Astronomy - Weekly Edition ·

2024/11/11

Streamed live on Nov 5, 2024. Last week we talked about the mission. This week we’ll talk about Euclid of Alexandria, the ancient Greek mathematician who inspired the mission. Let’s learn about his life and the ground breaking work that made so much of our modern mathematics possible. Hosted by: Fraser Cain and Dr. Pamela L. Gay.

Ep. 728: Solar Scientist Eugene Parker

365 Days of Astronomy - Weekly Edition ·

2024/09/30

Streamed live on Sep 23, 2024. Last week, we talked about the Parker Solar Probe. As always, we like to talk about the person who inspired the mission. What makes this amazing and different is that Eugene Parker was there to watch the launch of the mission that shares his name. Why is he so influential on solar astronomy?

Ep. 727: Parker Solar Probe

365 Days of Astronomy - Weekly Edition ·

2024/09/23

Streamed live on Sep 16, 2024. Let's look over the long life of the Parker Solar Probe as it explores the Sun and nearby worlds. The Sun! It’s that ongoing thermonuclear explosion that’s happening right over there! And although the Sun is necessary for life on Earth, we still have questions! So NASA has sent the Parker Solar Probe to visit the Sun up close, to get us some answers.

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.

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.
