Caltech physicist and engineer Gabriele Vajente explains how LIGO detects the faint ripples in spacetime known as gravitational waves. He explores the engineering behind the world's most sensitive measuring instruments, what we've learned from black hole collisions and neutron stars, and what future observations could reveal.

Hosted by Loretta Cannon. Today's 'guest' is the planet Neptune.  I'm telling the story of the discovery of Neptune 180 years ago in September, 1846. It was initially identified using mathematics rather than a telescope. This is a story of missed opportunities, undisclosed data, a bit of professional rivalry, and a controversy that some still argue today.    H'ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society.  We're here to share

Elias 2-24b is already several times Jupiter’s mass, yet its star system is estimated to be less than a million years old. This episode follows the discovery and asks how a gas giant can grow so massive, so quickly. We cover how astronomers use infrared and radio observations to study young planets, how they estimate ages, and why growing from tiny grains into a giant planet is a bit more complicated than it sounds. We also look at how an early forming giant planet can influence the fut...

Researchers have uncovered tens of thousands of organic compounds inside the Murchison and Aguas Zarcas meteorites using the world’s highest-resolution mass spectrometer. Atomic force microscopy also revealed rare images of individual extraterrestrial molecules in remarkable detail.The findings suggest that the chemical ingredients needed for life were widespread across the early solar system—and that the primordial space environment was far more chemically diverse than scientists expected.Thank you

Gay penguins and fish that change sex? How about birds engaging in lesbian behavior? We delve into the natural world and its often underreported queer behaviors that have frequently been steeped in historical prejudices and biases.  From mammals and birds to squid and beetles, queer behaviors and biologies are more prevalent than you might imagine among non-human animals. So just how queer is the natural world? Host Eleanor Higgs speaks to Josh Luke Davis, author of A Little Gay Natural

New research suggests that black holes of vastly different sizes follow the same rule when launching powerful radio jets.By studying stars torn apart by black holes, scientists found that jets appear when the feeding rate falls below a critical threshold. The discovery reveals a surprising universal pattern in how matter falls into black holes and could help astronomers predict when these powerful jets will appear.Thank you for listening to Bedtime Astronomy — your guide to the cosmos.

Hey! I'd love to hear your thoughts, send me a voice note.In this episode, we talk to houseplants, drawing a parallel between Jean's great-grandparents' experience with plants as apothecaries and the new outer-space odysseys.Lisa talks about her tragic loss of houseplants, and the poor cat takes the blame.

In this episode, we explore the extraordinary discovery of GRB 220706A, a record-shattering cosmic explosion at redshift z = 0.8577. While most gamma-ray burst engines die down within minutes, X-ray follow-up observations revealed active flaring continuing for 27 rest-frame days (~51 days in the observer frame). This sets the record for the latest central engine activity ever detected in a gamma-ray burst by a margin of roughly 21 rest-frame days.An Engine Duration for the Record Books: How combined

Europe's Jupiter probe comes home on Monday night and crosses Australia in a fully dark sky. Two teams, using two completely different techniques, both find something hiding inside the most famous planetary system we have ever photographed — and an Australian instrument is in the middle of one of them.

The paranormal comedy podcast where we probe Ye Olde Kings Head, which is more than 400 years old and is, these days, a hotel in Chester in the Northwest of the U.K. The place is now known as My Haunted Hotel and is part of the My Haunted Project but it’s not the hotel specifically we are probing, it’s the most haunted item in that haunted hotel, Grace. Grace is a porcelain doll and she may or may not have the spirit of a witch and a demon inside her, among others. Tune in to find out whether we
