Astronomers have taken their first image of an infant planet still developing around a newly formed star. Today we’re joined here at The Star Spot by André Müller, whose team is busy studying this baby world and has already discovered evidence of an atmosphere and possibly even moons, astounding knowledge of such a tiny speck 370 light years from Earth.

On a personal note, I want to dedicate this special 150th episode of The Star Spot to my amazing wife Denise and to our own newborn wonder, Lara Fong Trottier. Thank you for being the stars in my universe.

What secrets are hiding in the darkness on the moon? Tony sheds some light. And have you ever wondered just how we arrive at the mass of those thousands of extrasolar planets astronomers are busy studying?

Featured Guest: David Hamilton

The recent discovery of a lake of liquid water beneath the Martian south pole culminates a series of stunning discoveries that are forcing us to rethink the question of habitability on the Red Planet. Now two space missions are underway aimed at sites on Mars that may be the best candidates yet for life and boasting the most advanced bio detection instruments ever sent into space. To help us prepare, today we’re joined at The Star Spot by space physicist David Hamilton.

Join us at Solar System Social this Thursday, August 23rd

The Star Spot will be live on location at an upcoming event hosted by Solar System Social, a prominent Toronto speaker series. Join us for a provocative discussion entitled Who Deserves to Explore Space on Thursday, August 23rd at 6pm at Burdock pub. Visit

Featured Guest: Chuck Black

The Canadian Space Advisory Board was tasked with developing a plan to rejuvenate Canada’s declining world standing in space exploration. In 2017 the Board made a bold proposal that Canada designate space a national strategic asset and increase funding necessary for the “revitalization of Canada’s space capacity.”

But when in March 2018 the federal government released its annual budget, these calls were entirely ignored. The chair of the Canadian Space Advisory Board was so disappointed that she took the unusual move of publicly critiquing a government which seemed to be neglecting Canada’s space sector.

With little progress following years of industry consultation, where do we go from here? To help us understand how we got to this point and what can be done to reestablish Canada’s vision for space exploration, today we’re joined at The Star Spot by Chuck Black, the Editor of the Commercial Space Blog.

After the most extreme test yet of Einstein’s theory of General Relativity, Dave reports on the amazing results that will not surprise you in the least. Then Maya dazzles with news that a long-held theory about black holes has been disproved, leaving a black hole in our understanding of black holes. And Tony shares his joy at the birth of an endearing infant planet.

Today we turn our telescopes back around to study ourself. Our own solar system is undergoing a conceptual revolution. From its chaotic birth to its fiery end, our solar system is no longer seen as static and isolated. It is now understood to change and evolve, to offer great environmental diversity across its many worlds, and it now seems our solar system even interacts with the rest of the galaxy. In this special interregnum here at The Star Spot, today our news team of Tony, Maya and Dave take us on a journey across the history and the destiny of our solar system.

We’ve had interstellar asteroid tourists, but Tony wonders if we just found the first interstellar immigrant. Then Maya tackles the existential question of the sun’s ultimate demise. And finally Dave explores how the Earth-Moon love affair has profoundly changed us during our long years together.

Feature Guest: Brian Thomas

We have this impression of our planet as isolated from the rest of the universe, our lives cut off from the drama unfolding elsewhere in our galaxy. But what if the course of life’s evolution on Earth was intimately connected to events well beyond our solar system. It now seems likely that supernovae hundreds of light-years away have profoundly affected our history and may even account for climatic changes just as our species was emerging. Today we’re joined here at The Star Spot by astrophysicist Brian Thomas to explore this fascinating discovery.

 

About Our Guest

Brian Thomas is Professor in the Department of Physics and Astronomy at Washburn University where he leads the Washburn Astrobiophysics research group. His research focuses on the role of high energy astronomical events, in particular supernova and gamma ray bursts, on the atmosphere and biosphere of Earth. He is the principal investigator on a 3-year NASA grant to explore the terrestrial impacts of nearby supernovae.

Feature Guest: Stuart Ryder

When a massive star explodes in a supernova, it tends to gobble up all the attention. But what happens when that star has a binary companion with its own story to tell? That’s exactly what happened last month when the Hubble Telescope captured the first image of the surviving stellar companion to a supernova, and it turned out to be more than just a passive observer. Today we’re joined at The Star Spot by the discovery team leader Stuart Ryder to tell us how sibling rivalry might account for the origin of one unusual type of supernova.

Tony details the launch of a new space telescope that will take planet hunting to the next stage. Then Maya shares a tantalizing discovery from Jupiter's largest moon. And finally while we have trouble seeing individual stars in the galaxy next door, Dave reports on a star called Icarus that we just image despite it being 9 billion light-years away!

About Our Guest

Stuart Ryder is Head of International Telescopes Support at the Australian Astronomical Observatory and is responsible for coordinating Australia's usage of large telescopes around the world. His research interests include core-collapse supernovae and star formation in nuclear rings of galaxies.

The gravity, radiation and tidal forces at the very core of the Milky Way is kind of intense. That’s why astronomers have long doubted the possibility of star formation in such a hostile environment. And then everything changed with the discovery last fall of 11 sun-like stars living closer to the supermassive black hole at the centre of our galaxy then the distance between our sun and its closest neighbour. What does this breakthrough mean for our understanding of star formation and the possibility of life in what we once imagined were impossibly extreme environments? Today we’re joined here at The Star Spot by the discovery team’s leader Farhad Yusef-zadeh.

Feature Guest: Xinyu Dai

Last month astronomers announced the first ever discovery of extrasolar planets… in another galaxy! We’ve already confirmed almost 4000 planets beyond our solar system, but these have all been in a single galaxy, the Milky Way. But then last month a serendipitous discovery opened the door to a galaxy 3.8 billion light years away and it turns out it’s home to thousands upon thousands of planets. Today we're joined here at The Star Spot by co-discoverer Xinyu Dai to describe the unplanned discovery and whether this is the beginning of a new era in extrasolar extragalactic planetary astronomy.

Current in Space

The Andromeda Galaxy has tried hard to hide its past, but Dave exposes its dirty secrets. Then Maya numbers our minds with the discovery of the most distant supernova yet. And when psychologists studied the likely ramifications of first contact Tony found the results surprising.

Feature Guest: Scott Bolton

It’s our cosmic backyard, and yet our own solar system is still full of surprises. Now it turns out we were “totally wrong” when it comes to just about everything we thought we knew about Jupiter. That’s not me speaking, it’s Scott Bolton, principal investigator for the NASA Juno mission to Jupiter. From its magnetic field and atmosphere down to its very core, Jupiter is being rediscovered and transformed. Today we’re joined here at The Star Spot by Dr. Bolton to discuss the rewriting of our textbook on the solar system’s biggest world.

Current in Space

We've discovered a new family of extrasolar planets, and they're in a galaxy far, far away! Dave provides a trailer for the next episode of The Star Spot.
