The Star Spot

Feature Guest: Kevin Shortt

It’s a year that saw ups, such as the Dawn mission which became the first to study a dwarf planet. It was a year that experienced downs, like the tragic explosion of SpaceShipTwo and questions over the incident’s implication for space tourism. Through the ups and downs 2014 has been one fascinating year for space exploration. For a retrospective on the year that was, and a look at what’s on the horizon in 2015, today i’m joined at The Star Spot by Kevin shortt, the International Relations Officer for the Canadian Space Society.

And on the next episode Kevin Shortt will rejoin me here at The Star Spot for an international survey of the world’s contribution to space exploration. As new nations become major players how will our efforts to explore the unknown change in 2015 and beyond.

Tony and Anuj both wax poetic. Tony explains how the door has just opened on the road to Europa, Jupiter's ocean world and a candidate int he search for life. Then Anuj on the very long road of Voyager, 40 years travelling and just getting started.

About Our Guest

Kevin Shortt has worked in the space industry since 1996 and has participated in some of Canada’s largest space missions. He was Mission Planner for the RADARSAT-1 program at the Canadian Space Agency and a member of the design team responsible for the lidar instrument on board NASA’s Mars Phoenix Scout mission. He currently works at the Institute for Communication and Navigation at the German Aerospace Center in optical communications. Kevin served as President for the Canadian Space Society from 2008 until 2012 and is currently its International Relations Officer.

The disks of matter that form around mysterious B emission stars are providing astronomers with a unique place to study a ubiquitous phenomenon in our universe. Disks are everywhere and on every scale, from the birth of solar systems to the structure of galaxies. Today we’re joined here at The Star Spot by Carol Jones and Aaron Sigut to conclude our two part series on dynamic and lively B emission stars and the disks that excite them.

Why did asteroid belt member Ceres never form into a fully fledged planet? That's what Dawn may soon find out when it arrives next month. Is the moon the 8th continent? Anuj explains how mining is getting closer to reaching the final frontier. And worried about aging? Dave shares the discovery of an 11 billion year old planet, still alive and well.  

About Our Guests

Let’s pick up where we let off with our two guests from Western University. Dr. Carol Jones is Associate Dean of Graduate and Postdoctoral Studies in the Faculty of Science, as well as associate professor and associate dean in the physics and astronomy department. Aaron Sigut is Associate Professor of Astronomy in the Physics and Astronomy Department.

Disks are ubiquitous in our universe. They are found in the spiral arms of galaxies. They are found among new and old stars, whether in the protoplanetary gas associated with stellar births or the black holes which follow many stellar deaths.

Today we have a special treat. I’m excited to be joined by both Carol Jones and Aaron Sigut here at The Star Spot for the first of a special two-part series. We’ll find out why disks are such common features of our universe, and how they figure prominently into a mysterious phenomenon known as B emission stars, which are among the hottest, most energetic and most mysterious of stellar phenomena.

Dave reports the probability of exoplanet habitability may have just increased significantly with scientists rethinking the once assumed life-preventing effect of planetary tidal locking. Then Laura explains the famous Pillars of Creation in the Eagle Nebula seem to be eroding away, and may have already vanished. Anuj shares new evidence that the asteroid which wiped out the dinosaurs was a truly global event. And has Beagle 2 been resurrected? Celine with new images from Mars that are shining light on the tragic fate of a spacecraft whose trip was no more smooth than that of its namesake.

About Our Guest

Today two distinguished astronomy scholars from Western University are joining us here at The Star Spot. Dr. Carol Jones is Associate Dean of Graduate and Postdoctoral Studies in the Faculty of Science. Aaron Sigut is Associate Professor of Astronomy in the Physics and Astronomy Department. They both share research interests in circumstellar disks around hot stars, which we will get into in a series of conversations with both academics.

Feature Guest: Jayanne English

 

We've all been blown away by those jaw dropping majestic images of the cvosmos. But would you feel deceived to know that few of those images show what the eye would truly see? Today guest host Dave Kirsch welcomes Professor Jayanne English at The Star Spot to discuss the tension between art and science in astronomy.

Current in Space

Dave alerts us to the likelihood of future collisions between our sun and its nearby stellar neighbours, explaing why a near miss can still make a big impact. The debate about the status of Pluto is sure to heat up as Tony reports on the New Horizons mission which recently came out of hibernation in preparation for its final approach to the dward planet. And Anuj shares new insights into the cause of mysterious high altitude aurora.

About Our Guest

Jayanne English is Professor in the department of Physics and Astronomy at the University of Manitoba. Her interests are in the origin of structure in galaxies, including galactic halos. She held a post-doctoral position at the Space Telescope Science Institute and was Visitor at Oxford University (2013) and Visiting Scholar at the Australian National University (2009). She is also highly involved in merging the arts and the sciences through astronomical imagery. Professor English led an interactive art project in honour of the Internal year of Astronomy entitled Seeing is Believing.
