Pluto is out, but could we have a new ninth planet to replace it? Learn of triumphs and pitfalls from the history of planetary astronomy in this week's PhysicsCentral podcast.

A New Ninth Planet?

PhysicsCentral's Physics Buzz Podcast host Meg Rosenburg journeys to the Hanford observatory for an exclusive interview with one of the scientists behind LIGO's detection of gravitational waves! 

The Truth About Gravitational Waves

Bubbles trapped deep in arctic ice contain air that's been encased for hundreds of thousands of years! Find out what we can learn from ancient oxygen on this week's PhysicsCentral podcast!

Of Ice Cores & Isotopes

This week's PhysicsCentral podcast explores stellar archaeology, and the violent origins of heavy elements.

Star-chaeology: The Next (Stellar) Generation

In this edition of the PhysicsCentral podcast, we hear from a few teams who are still in the running for the CubeQuest Challenge: a contest for homegrown teams to build their own small satellites — cubesats — and compete against each other by demonstrating technological feats. Five million dollars in prize money will be divided among teams who can get into orbit around the moon, maintain a stable orbit for a long time, or make it almost all the way to Mars’ orbit while still communicating with Earth.

Drag Racing Cubesats for NASA's CubeQuest Challenge

LIGO and Virgo's latest gravitational wave detection brings an entirely new component to the table, and promises deeper insights into processes like heavy element formation.
