Ep. 716: The God**** Particle – Remembering Peter Higgs

Ep. 716: The God**** Particle – Remembering Peter Higgs

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. 714: Orbital Resonances

Ep. 714: Orbital Resonances

Several of the planets and moons in the Solar System are in orbital resonance, orbiting in a geometric lockstep. And not just the Solar System, astronomers have found the same resonances in other star systems.

Ep. 713: Solar System Volcanoes – An Update from LPSC 2024

Ep. 713: Solar System Volcanoes – An Update from LPSC 2024

Last week was one of the most exciting meetings we’ve seen from the Lunar and Planetary Science Conference, with hundreds of announcements and discoveries from various missions. One theme kept coming up, the Solar System is more volcanically active than we thought. Today, we’ll explore volcanism on other worlds.

Ep. 712: How Peer Review Fails

Ep. 712: How Peer Review Fails

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. 707: What Goes Into Sample Return Missions for the Moon and Mars?

Ep. 707: What Goes Into Sample Return Missions for the Moon and Mars?

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, were we study them with proper equipment.

Ep. 706: China’s Space Program

Ep. 706: China’s Space Program

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

Ep. 705: Water Worlds – Looking for Life Beyond Earth

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

Ep. 704: NASA’s Juno Releases New Images

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. 700: Things We Got Wrong

Ep. 700: Things We Got Wrong

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?

Ep. 694 – Mission Roll Call Part 3: Sun, Mercury, and Venus

Ep. 694 – Mission Roll Call Part 3: Sun, Mercury, and Venus

Our journey through space missions continues. Now we move away from the Earth to the rest of the solar system. What’s out there orbiting, roving and flying on other worlds and in interplanetary space. Today we look inward and we’ll talk about the missions studying the Sun, Mercury and Venus.

Ep. 693 – Mission Roll Call Part 2: Looking Outward from Earth

Ep. 693 – Mission Roll Call Part 2: Looking Outward from Earth

Last week, we brought you up to speed on the spacecraft which are helping to study Earth from above. Many of our missions are in Earth orbit but looking outward to study the Universe. Today, we’ll talk about the missions close to home, helping us understand our place in the cosmos.

Ep. 692 – Mission Roll Call Part 1: Orbiting Earth

Ep. 692 – Mission Roll Call Part 1: Orbiting Earth

It’s time for another series. This time we’re going to look at the missions that are currently in place across the Solar System. Today we’ll start with the key missions here on Earth, studying the planet from above and looking out into the Universe.

Ep. 691: Jupiter’s Changing Red Spot

Ep. 691: Jupiter’s Changing Red Spot

Jupiter’s Great Red Spot is one of its most iconic features, first seen hundreds of years ago. Although it’s certainly long-lasting, it’s been changing in size over the last few decades, shrinking and changing in color. Is it fading away? And what can the changes tell us about storms on giant planets?

Ep. 690: Climate on Mars – From Ice Caps to Dust Storms

Ep. 690: Climate on Mars – From Ice Caps to Dust Storms

We’ve looked at Earth’s changing climate, now let’s see what it’s like for another world: Mars. Much looks familiar, but some of it is totally alien, from ice caps of frozen carbon dioxide to planetary dust storms that can obscure the entire world from view.

Ep. 688: What’s Next? Looking Ahead to Season 17

Ep. 688: What’s Next? Looking Ahead to Season 17

Once again, we’ve reached the end of a season here on Astronomy Cast, and it’s time for the summer hiatus. But the Universe never takes a break. What can we expect to happen over the summer while we’re catching up on our reading, building our gardens and planning for Season 17

Ep. 687: Prepping for the Moon

Ep. 687: Prepping for the Moon

We’re going back to the Moon. In the next few years humans will set foot on the Moon again, ideally this time to stay. But this will be different than the Apollo era, going to the scientifically fascinating, and difficult southern pole of the Moon. What needs to be done to prepare the way back to the Moon?

Ep. 686: Ice in the Shadows

Ep. 686: Ice in the Shadows

The permanently shadowed craters on the Moon are the focus of so much research. That’s because they seem to contain vast reserves of water ice. Water we could use for oxygen, propellant and so much more, but also, to help us understand where the Earth’s water came from.
