Feature Guest: Guillem Anglada-Escudé Recently headlines buzzed with news of the discovery of the nearest exoplanet that we will ever find. And it looks like it could very well be habitable. Proxima b, at just over 4 light years from Earth, is quickly fuelling the imagination, with one foundation already planning a spacecraft mission to the world within a single generation. Today we’re excited to be joined at The Star Spot by Guillem Anglada-Escudé, head of the team responsible for this amazing discovery. Current in Space About Our Guest Dr. Guillem Anglada-Escudé is Lecturer at the School of Physics and Astronomy at Queen Mary University London in the UK. His research interests range from exoplanets to fundamental physics. He received his PhD from the University of Barcelona. Dr. Anglada has served as "Councillor of Culture, Citizen participation and Youth" for the city council of Ullastrell, a small village near Barcelona.

Feature Guest: Brian Fields By now we are all familiar with the theory that an asteroid brought to an end the age of the dinosaurs, a period of domination that had lasted 167 million years. But asteroids are not the only harbingers of doom that lurk in the darkness of space. Today we’re joined here at The Star Spot by Brian Fields, whose research team has found evidence linking supernovae events in deep space to mass extinction events in deep time. Current in Space Tony reports on the mystery of the vanished star. Then Jeff describes electromagnetic flare from a gravitational wave event caused by two merging black holes. And Camilla brings news of two new super-Earths. Finally Amelia and Priyanka offer an explanation for radio waves caused by pulsars. About Our Guest Brian Fields is Professor of Astronomy and Physics at the University of Illinois

Feature Guest: Sandro Mereghetti Fast radio bursts are a new mystery in astronomy. These highly energetic events of unknown origin were first discovered in 2007 out in deep space. Now a team is reporting the first fast radio burst to emanate from our own Milky Way Galaxy. Today we’re joined here at The Star Spot by Sandro Mereghetti, whose team is on the hunt for the source of this unusual phenomenon.   Current in Space Camilla shares the remarkable discovery, or rather re-discovery, of the heartbeat of a supermassive black hole in a distant galaxy, found still alive and kicking ten years after being first observed. In addition to the supermassive black hole shaping the environment at the centre of our home galaxy, Amelia and Priyanka explain that something else there is also calling the shots (and no, it's definitely not like what we saw in Star Trek V). In other black hole news, Finally, Jeff brings us back down to Earth (though still above Earth), as SpaceX is launching ever more Starlink satellites into orbit to provide high-speed Internet coverage to citizens of our planet. There's only one problem: the future of ground-based astronomy may be at stake. About Our Guest Sandro Mereghetti is research staff member at the National Institute for Astrophysics in Milan.

Feature Guest: James Slifierz The NASA Space Apps Challenge is a feverish annual hackathon engaging teams of coders, scientists and storytellers around the world. Each year thousands of participants in over 75 countries compete to solve real-world problems in Earth and in space.  As the Challenge celebrates its 10 year anniversary it faces one of the most demanding challenges of our generation: COVID-19. To discuss how NASA is turning the global pandemic from a challenge into an opportunity, today we’re joined here at The Star Spot by James Slifierz, Co-founder and CEO of Skywatch and a 2014 NASA Space Apps global winner.  Current in Space Camille reports on the closest black hole to Earth. Then Jeff announces the Artemis Accords. Anshool shares a new high-resolution infrared image of Jupiter. Finally Amelia and Priyanka describe a planetary system with six planets that orbit in near-perfect rhythm.  About Our Guest James Slifierz is Co-founder and CEO of Skywatch, a private company with a mission to make earth observation data accessible to developers for a wide variety of applications. He is also responsible for bringing the NASA Space Apps Challenge to Waterloo, Ontario, where each year it proves to be one of the top locations in the world.

Feature Guest: 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. That’s right, Planet Nine might be Black Hole One, our own solar system’s very first singularity. Today we’re joined here at The Star Spot by astrophysicist Jakub Scholtz, co-author of a new study making the case for this fascinating proposal.  Current in Space Tony celebrates the 30th anniversary of the Hubble Space Telescope. Then Jeff reports on water loss from mysterious interstellar comet Borisov. About Our Guest Jakub Sholtz is Junior Research Fellow at the Institute for Particle Physics Phenomenology at Durham University in the UK. He earned his PhD at the University of Washington, where he was awarded the Hadley Fellowship, and performed a Postdoctoral Fellowship at Harvard University.

Feature Guest: 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.  Current in Space A supergiant haul of stories this week. First Camilla reports on the largest ozone hole ever seen over North Pole. Then Jeff shares evidence of an elusive mid-sized black hole. And Anshool brings news of many more satellite galaxies around the Milky Way. Followed by Amelia and Priyanka’s obituary on the passing of astronomer Margaret Burbidge. Finally Joseph updates us on the proposed mission to Enceladus. About Our Guest Emily Levesque is Assistant Professor of Astronomy at the University of Washington. Previously she worked as a Post Doc at the University of Colorado, during which she held Einstein and Hubble Fellowships. She is a recipient of the Sloan Fellowship and the Annie Jump Cannon Award. Her work focuses on massive stars and galaxy formation.
