The Star Spot

Feature Guest: Brian Schmidt

The 1929 discovery of the expanding universe by Edwin Hubble forever changed our picture of the cosmos and our understanding of our place in the universe. In 1998 we learned that wasn’t the only surprise. That’s when two teams of astronomers announced that the expansion of our universe isn’t slowing down as everyone assumed. Its speeding up. Today we're joined at The Star Spot by Distinguished Professor Brian Schmidt who won the Nobel Prize for discovering our accelerating universe.

Current in Space

Anuj describes the Orion spaceflight, the first mission since Apollo eventually aimed at deep space. Then Tony wonders if the stuff of life could seed itself on other worlds following the disocvery that DNA returned from the exposure to the vacuum of space in good working order. And Dave extends the lifetime for Mars’ watery past after learning an ancient lake may have lasted tens of millions of years. Finally Celine explains how “cliff-bots” now being tested in the Moroccan desert may one day dig up deposits left over from such long extinct bodies of water.

About Our Guest 

Dr. Brian Schmidt is Distinguished Professor at the Australian National University Mount Stromlo Observatory and holder of an Australian Research Council Federation Fellowship. In 2011 Schmidt received the Nobel Prize in Physics for his co-discovery that the universe isn’t merely expanding, it’s actually accelerating in its expansion. Shmidt is Fellow of the Royal Society, a recipient of the Pawsey Model, the Dirac Medal and the Shaw Prize in Astronomy.

It’s a phenomenon so mysterious one astronomer wondered if it could be evidence of an advanced extraterrestrial intelligence. Meet blue straggers, the black sheeps of the stellar family. Today we're joined at The Star Spot by Professor Alison Sills to learn all about the stars that shouldn’t exist.

Current in Space

Dave mesmerizes us with the carnival funhouse like effect around black holes, where the warping of space and time is so intense you can see the front and back of blackholes simultaneously. Celine discusses an upcoming unmanned mission to drill the moon for lunar samples and establish the viability of a future human outpost. And while you may have heard of the Great Red Spot on Jupiter, Tony wonders if the entire spot is red, why it's red and why so little else on the gas giant shares the iconic colour. Finally Yonna brings us news of Europe's first space plane set to launch shortly.

Brown dwarfs: giant planets or failed stars? The debate rages on with comparable intensity to the surprisingly violent storms seen to roil these fascinating bodies. To help settle the debate, and for cutting edge discoveries of brown dwarfs and their startling behaviour, Stanimir Metchev joins Justin Trottier at The Star Spot.

If a brown dwarf is neither a planet exactly nor a star exactly, what is it exactly? What keeps it from collapsing? And since they aren’t necessarily brown, what’s in the name? Metchev and Trottier then discuss the weird and surprising behaviour of brown dwarfs, the ubiquity of their massive storms and their role in helping us study the clouds of extrasolar planets,

Feature Guest: Paul Delaney

The next time you look up at the night sky, struck dizzy by the sheer number of stars shining down on you, here’s something to consider. On average each star host at least one planet. That’s the accumulated result of our exoplanet hunting efforts to date. To help us explore the implications of this profound discovery and to make sense of our zoo of exoplanets, from Super Earths to Hot Jupiters and everything in between, Professor Paul Delaney joins Justin Trottier at The Star Spot.

We’ve focused much attention on exoplanet discoveries. Today we step back and provide some perspective. Professor Delaney takes us from the earliest planet hunting pioneers all the way to the latest technological developments that are pushing the distance of our planetary discoveries, reducing the size of the objects we are able to detect, and leading us on to the next frontier: exoplanet atmospheres.

Professor Delaney explains his surprise at the ubiquity of so-called “rogue planets” and shares his touching story of becoming an astronomer despite living with albinism. Though in his own words he does not have a good relationship with the sun, he has fostered a great one with the stars, and he works to share his infectious enthusiasm with the world.

Current in Space 

Dave shares the discovery of an exoplanet found near the all important “frost line,” the first time we’ve found a planet with a history potentially similar to that of Jupiter. Benjamin describes how the upcoming James Webb Space Telescope may search the atmosphere of exoplanets for signs of life - including long self-destructed life! Closer to home, Anuj tells of a new spacecraft being sent to sample an asteroid for organics. And Denise wonders if the next space race will be far more crowded than the last one.

Feature Guest: Marshall McCall


Today we’re joined by Marshall McCall for a special interview originally held in front of a live audience at an event hosted by the University of Toronto Astronomy and Space Exploration Society.

 

In front of a live audience, Professor McCall joins Justin Trottier for a wide ranging discussion on all things galaxies. McCall tells how he wound up as a gardener at the Dominion Astrophysical Observatory, briefly the largest telescope on Earth, and then off to the opposite corner of the world working at observatories in Australia. A debate with the audience ensues over northern versus southern skies.

 

The two then discuss whether our galaxy is unique, the importance of dwarf galaxies, and get controversial exploring alternative theories of gravity. McCall explains the role of dark matter in giving rise to the superstructure we see as cosmic webs of sheets, filaments and voids. If dark matter dominated our past, the Andromeda galaxy will dominate our future when, in 3 billion years, we collide.

 

The conversation concludes with a focus on McCall’s recent research on our mysterious local sheet of galaxies. Out to 20 million light years galaxies surrounding the Milky Way appear to lie on a surprisingly flat sheet. McCall describes this puzzling structure, which he dubbed the “council of giants,” how work with his graduate student George Conidisis leading to startling revelations that suggest our neck of the woods might have some special qualities after all.

 

Current in Space

 

What effect does microgravity have on an astronauts internal organs? Ben gets to the heart of the matter. Then Anuj introduces us to an object called a Centaur which lives like an asteroid, behaves like a comet and has rings like a gas giant. And finally Dave shares the startling announcement  of an equally puzzling new addition to our family, a dwarf planet in the inner Oort Cloud and the possibility that its discovery could point to a super-Earth far out beyond Pluto

The early universe is a place of mystery and paradox. But the one thing we are sure of is that to understand our far future we must look to our ancient origins. To help us make some progress today Mark Halpern joins Justin Trottier at The Star Spot.

The two focuse on the 2012 Gruber Cosmology Prize which was awarded to Halpern's team for work with the NASA Wilkinson Microwave Anisotropy Probe which used sound ripples from the earliest moments of creation to come up with key findings:

- determining the universe's age with better precision than ever before, at 13.8 billion years (while still unresolved is the paradox that quantum mechanics and gravity suggest the universe should live no longer than a single second).

- assigning ratios to the constituents of the universe: ordinary matter, dark matter and dark energy

- studying the overall shape and geometry of the univers

- finding evidence of inflation, a theory that explains additional paradoxes of the early universe

The two then discuss CHIME, a new Canadian mission studying left over ripples from the big bang and evidence of the recent expanstion history of the universe

On today's episode of The Star Spot we continue our highlights of the 2013 Canadian Space Summit. Justin Trottier is joined by Peter Garland, Vice President of Advanced Programs with MDA. The two discuss how satellite communication became the technological foundation that brought together a nation. They document the important milestones in communication innovations and the role they continue to play in connecting geographically expansive regions in our world. Garland concludes with stories of new and unique applications of satellite communications in fields ranging from telehealth, tele-education and even the criminal justice system.

Feature Guest: Catherine Hazin

We begin our coverage of the 2013 Canadian Space Summit held in Ottawa in November 2013, with the first of five feature Star Spot interviews with guests at the Summit.

Co-host Denise Fong was pleased to be joined by artist Catherine Hazin at The Star Spot on location. Catherine was showcasing artwork on behalf of over 50 internationally acclaimed space artists as part of the Canadian Space Summit’s space art exhibition: The Inexorable Revolutions of Art.

Denise and Catherine discuss the little trodden territory where science and art overlap and the link between art and space exploration. What is the function that art serves for space exploration and what value does it add to the human interest in observing the Universe and in contemplating our ultimate human frontiers?


Historically in the 1800s, artists accompanied explorers on their excursions to discover the frontier of America, and their contributions to communicating the images of the new lands were prolific and highly valued, from the paintings of Thomas Moran and Albert Bierstadt to Frederick Church, considered the highest paid painter of his day in 1872. More often than not, Church was able to finance his very own exploratory expeditions by painting Earth’s new wonders, like the north pole Aurorae, icebergs of the Arctic sea, and volcanoes in South America.

The wonders of earth when they were first discovered inspired volumes of artwork and depicted places not yet known such as Yellowstone, and Yosemite, now protected national parks in the West. Today these visuals of the previously unknown American Western frontier serve to document our human heritage, and were the basis of immense inspiration, sense of adventure, risk, danger, and of the unknown.

So bringing to the present what we have seen from history, what about the artist’s role today for the human exploration…of space – the final frontier?


Denise and Catherine discuss the renaissance in the connection between art and the nature of exploration and discovery. How relevant is space art today? What function does it serve space exploration? Is it possible for artists’ impressions, and artistic works, to disappear into history just as it did alongside the disappearance of Earth’s new frontier lands? And if we leave out the art, how would space exploration suffer?

Dave shares the first cloudy weather forecast for a Super Earth extrasolar planet. Then Arjun excites us with new data anticipated from the spacecraft GAIA, a super sensitive billion pixel camera set to survey a billion stars in the Milky Way Galaxy (and costing some billion dollars). Finally Benjamin on how disappointment quickly turned to delight when researchers with the Hunt for Extromoons with Kepler (HECK) project made one heck of a discovery: no moon but the least massive gaseous world we've yet found.
