Live Stream the December 14th, 2020 Total Solar Eclipse

On Deember 14th a Total Solar Eclipse will be visible in southern Chile and Argentina.

Total solar eclipse

While we can’t be there to see it live there will be a number of live video streams set up along the path of totality.

Below are a couple links you can access to witness the eclipse as it happens.

This occurs in the morning hours Edmonton time. Maximum eclipse is at 9:13:28 MST, Times at the live stream sights will vary.

Titans of the Early Universe: The birth of the first black holes

 

At the heart of every galaxy lies a giant—a supermassive black hole anywhere from millions to billions of times the mass of our Sun. Our understanding of these mysterious objects is growing quickly;  last year, the first image of a black hole was released by the Event Horizon Telescope, and this year the Nobel prize was awarded in part for the discovery of a supermassive black hole at the centre of our own Galaxy. Many basic questions remain unanswered, however, including how these black holes formed in the first place, and how they became so staggeringly massive. In this talk, I’ll show how the recent revelation that black holes a billion times the mass of the Sun already existed during the first billion years of cosmic history presents a stark challenge to our understanding of how they formed, and I’ll highlight the recent and upcoming efforts in Canada to unravel the mysterious origins of these primordial titans.

“Birth and evolution of debris disks: Windows into planetary systems”

Debris disks were identified relatively recently in astronomical terms, by the first all-sky infrared survey satellite IRAS. These interesting objects are continually created in planetary systems, both old and young, via collisions of comets and asteroids in orbit around stars.  The collisions create newly visible dusty disks, often detectable many millions of years after the dispersion of the protoplanetary disks which typify the youngest phases of star and planet formation.  I will describe what we understand about the origins, evolution and structure of these disks, as well as their role in planetary systems. Recent discoveries suggest they may be inexorably linked to the earliest phases of planet formation. Finally I will discuss some of the more esoteric examples of these disks which can show remarkable variability over relatively short periods of time.

 A Canadian Perspective on The Far-Infrared Universe

Over half of the energy emitted by the Universe appears in the relatively unexplored Far-Infrared (FIR) spectral region, which is virtually opaque from the ground and must be observed by space-borne instrumentation. The European Space Agency (ESA) Herschel and Planck Space Telescopes provided the first full-sky and broad-band access to the cosmos in the FIR spectral region.  Herschel was comprised of three instruments which conducted imaging and spectroscopy in the FIR, including the Spectral and Photometric Imaging Receiver (SPIRE), with the Canadian contribution to SPIRE directed by the University of Lethbridge Astronomical Instrumentation Group (AIG). This lecture also introduces the Far-Infrared Universe, and Canadian perspective on associated telescopes and scientific instrumentation, past, present, and including future missions and mission concepts. Targets of interest include relatively nearby star formation, all the way out to the oldest photons available to us from the cosmic microwave background.
