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 ..read more

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 ..read more

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 2 ..read more

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 ..read more

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 we ..read more

Feature Guest: John G. 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.   Current in Space Jeff starts us off with a bang... the largest ..read more

Feature Guest: Geoffrey A. 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. Current in Space After NASA's InSight lander touched down on Mars in late 2018, it's already gathering fa ..read more

Feature Guest: 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. Current in Space Stars like the Sun are a no-brainer when it comes to finding habitable planets, but Amel ..read more

Feature Guest: Guo Qi 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.  Current in Space NASA's newest planet hunter has made its most remarkable discovery yet: an Ea ..read more

Feature Guest: Jay Melosh If we should find creatures crawling around Titan or swimming under the ice sheets of Europa or Enceladus, they will almost certainly turn out to be the result of a second genesis, those creatures truly alien in the most profound sense. That startling conclusion follows from a series of groundbreaking simulation that found it exceedingly unlikely that life can be successfully transferred between the worlds of our solar system. To unpack the significance of this conclusion, today we’re joined here at The Star Spot by geophysicist Jay Melosh, who caused an uproar when h ..read more
