Ep 720: Galaxy Series – Elliptical Galaxies

Ep 720: Galaxy Series – Elliptical Galaxies

Our galaxy series continues with elliptical galaxies. Unlike other types, these are large, smooth with very few distinguishing features. They’re filled with red and dead stars, a clue to their evolution. https://youtube.com/live/K9TuZ8RGb-Y

Ep 720: Galaxy Series – Elliptical Galaxies

Ep. 719 – Galaxy Series: Spirals

Our galaxy series continues, on to spiral galaxies. In fact, you’re living in one right now, but telescopes show us the various shapes and sizes these galaxies come in. Thanks to JWST, we’re learning how these spirals got big, early on in the Universe....

Ep. 718: Galaxy Series – Dwarf Galaxies

Ep. 718: Galaxy Series – Dwarf Galaxies

It’s time to begin a new mini-series, where we’ll look at different classes of galaxies. Today, we’ll start with the dwarf galaxies, which flock around larger galaxies like the Milky Way. Are they the building blocks for modern structures?

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. 711: NASA Innovative Advanced Concepts (NIAC)

Ep. 711: NASA Innovative Advanced Concepts (NIAC)

NASA works on many missions using tried and true technology, but they also invest in creative ideas that could drive the future of space exploration. It’s called NASA’s Innovative Advanced Concepts or NIAC.

Ep. 709: Space Weapons

Ep. 709: Space Weapons

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?

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. 703: Solar Maximum of Doom? Maybe

Ep. 703: Solar Maximum of Doom? Maybe

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?

Ep. 702: Moonshot 2024 – Go or No Go?

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?

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?
