    Episode 182: Planet Nine or Black Hole One, with Jakub Scholtz

    Episode 182: Planet Nine or Black Hole One, with Jakub Scholtz

    We’ve long believed that membership in the solar system’s planetary family was limited to those eight planets we learned about in grade school. But then astronomers began to raise the possibility of a new super-Earth-sized planet, five to ten times the mass of Earth, orbiting far off in the outer solar system. Now if you thought the concept of Planet Nine was astonishing, consider if the mysterious body wasn’t a planet at all - but a black hole.

    Episode 181: Reports of Betelgeuse’s Death Are Greatly Exaggerated, with Emily Levesque

    Episode 181: Reports of Betelgeuse’s Death Are Greatly Exaggerated, with Emily Levesque

    In December 2019, amateur and professional astronomers held their breath as the red supergiant Betelgeuse started dimming beyond anything on record, a sign the behemoth might be preparing to go supernova. But over the ensuing few months, things seemed to be returning to normal for this fascinating star. To solve the mystery, a team set out to investigate this bizarre behaviour and to shed light on the fate of Betelgeuse. Today we’re joined here at the Star Spot by Emily Levesque to discuss their findings.

    Episode 180: Wormholes through Space and Time, with John Cramer

    Episode 180: Wormholes through Space and Time, with John Cramer

    They are the stuff of science fiction, but wormholes are also the subject of intense scientific debate. Can wormholes provide a mechanism for faster than light travel through space and, even more intriguing, do they open the door to travel through time? Today we’re joined here at The Star Spot by one of the world’s foremost authorities on wormholes, Professor John G. Cramer, to share results from his thought experiments on wormholes and his laboratory experiments aimed at changing the past.

    Episode 179: Dreams of Floating Cities, with Geoffrey Landis

    Episode 179: Dreams of Floating Cities, with Geoffrey Landis

    When we think of terraforming, we probably envision turning the Red Planet blue. But Mars isn’t the only world in our solar system that ambitious scientists have considered transforming. Imagine a network of floating cities in the clouds of Venus, or sailing ships plying the oceans of a newly thawed moon in the outer solar system. Today we’re going to dream here at The Star Spot with NASA scientist and award-winning science fiction author, Geoffrey Landis.

    Episode 178 Sibling Rivalry at the Centre of the Galaxy, with Smadar Naoz

    Episode 178 Sibling Rivalry at the Centre of the Galaxy, with Smadar Naoz

    We’ve long known that most galaxies contain at their core a supermassive black hole that can be millions of times the mass of the sun. But now researchers are discovering galaxies with more than one supermassive black hole at their centre. To understand the implications of this discovery and what it could mean about the history of the Milky Way, should our own galaxy be among this collection, today we’re joined here at The Star Spot by astrophysicist Smadar Naoz.

    Episode 177: The Case of the Missing Dark Matter, with Guo Chi

    Episode 177: The Case of the Missing Dark Matter, with Guo Chi

    Dark matter vastly overshadows ordinary matter in our universe. Wherever astronomers turn their telescopes they find galaxies dominated by dark matter. But all that changed recently with the first discoveries of dwarf galaxies suspiciously deficient in dark matter. To make sense of this baffling finding and how it relates to our Milky Way’s own local dwarf galaxies, today we’re joined here at The Star Spot by study lead Professor Guo Qi from the Chinese Academy of Science.
