Speaker for 13 May: Steve Mairs

 

steve mairsAt 7:30 PM, 13 May 2016, at the Sunshine Coast Art Centre, 5714 Medusa St., Sechelt, Steve Mairs, a PhD student in astronomy at the University of Victoria and the outreach supervisor for the U Vic Astronomy department, will be our speaker. The topic of Mairs’ talk is Where Baby Stars Come From, and Why it’s Important to Know!

In this talk, Mairs will examine the birth of a sun-like star and introduce some of the research being performed in Victoria to further our knowledge on this subject. Mairs’ main focus will be on the Orion Molecular Cloud, a giant star-forming region in the Milky Way which encompasses the famous Orion Nebula. Mairs will present images of what the Orion Nebula looks like at submillimetre wavelengths and show how these often overlooked observations can provide vital information into the young lives of stars. By studying “where baby stars come from”, we can make links to present day observations of star clusters, supernova explosion rates, the formation of planets, and, in effect our very own origin story.

Admission is free: donations gratefully accepted at the door.

8 April 2016- Dr. Catherine Johnson: The InSight Mission

dr. Catherine Johnson

At 7:30 PM, 8 April 2016, at the Sunshine Coast Art Centre, 5714 Medusa St., Sechelt, The Sunshine Coast Centre welcomes Dr. Catherine Johnson from UBC, whose topic will be The InSight Mission: Journey to the Center of Mars

Orbital and lander missions to Mars over the past several decades have revealed a wealth of information about the planet’s surface geology and raised many unanswered questions about the planet’s past climate conditions. Key to answering many of these questions is understanding the planet’s deep interior, about which we know very little. Mars’ interior is also a fingerprint for the earliest stages of evolution of any of the terrestrial (rocky) planets in the inner solar system. The InSight mission, planned for launch in 2018, will deploy a seismometer, a heat flow probe and several other instruments on the surface of Mars. I will talk about how InSight will monitor the Red Planet’s “vital signs” – “pulse” (seismicity), “temperature” (heat flow) and “reflexes” (wobbles) – to determine Mars’ interior structure and evolution.

Admission is free: donations gratefully accepted at the door.

 

Extremely Large Telescopes

paul hickson

At 7:30 PM, 11 March 2016, at the Sunshine Coast Art Centre, 5714 Medusa St., Sechelt, Dr. Paul Hickson will do a presentation on Extremely Large Telescopes. Paul Hickson is a Professor in the Department of Physics and Astronomy at the University of British Columbia. He obtained a BSc in Physics from the University of Alberta in 1971, and a PhD in Astrophysics from the California Institute of Technology in 1976. Dr. Hickson has research interests in several areas of extragalactic astronomy, including galaxies, clusters of galaxies, active galactic nuclei and cosmology. He also spends time developing new astronomical instruments, such as liquid-mirror telescopes, robotic telescopes, and instruments to measure atmospheric turbulence. He currently serves as Co-chair of the Scientific Advisory Committee for the Thirty Meter Telescope and was Project Scientist for its adaptive optics system.

In the coming decade three next-generation optical-infrared telescopes are expected to see first light. The Giant Magellan Telescope, the Thirty Meter Telescope and the European Extremely-Large Telescope will be the world’s largest, with apertures ranging from 22 to 39 metres. Employing advanced adaptive-optics systems and a suite of sophisticated instruments, these telescopes will have as much as four times the resolution, 16 times the light gathering power, and more than 200 times the sensitivity of today’s largest telescopes. Dr. Hickson will provide an overview of the key scientific programs that are driving these projects, and the technologies that make them possible.

Admission is free, donations gratefully accepted.

Dr. Patrick Cote: 9 October 2015

dr patrick Cote

Our Speaker for 9 October 2015 at the Sunshine Coast Arts Centre, 5714 Medusa St, Sechelt, will be Dr. Patrick Cote of the National Research Council, Herzberg Astronomy and Astrophysics Centre, Victoria, BC. His topic will be: "Skies Wide Open: Canadian Plans for Wide-Field Astronomical Facilities in the Coming Decade."

"Many of the most pressing open questions in astronomy -- ranging from the nature of Dark Energy to the origin of the Milky Way --- require precise observations of faint sources scattered over the ultra-wide fields. For this reason, a number of wide-field telescopes are now being developed by the international astronomical community. Most of these facilities are expected to see "first light" in the 2020s.

"Canada, which has a proud history in wide-field astronomy, is keeping pace through participation in several of these projects. In addition, the Canadian astronomical community has, for several years, been developing plans for its own wide-field facilities. In this talk, I describe two exciting projects that are under active investigation in Canada. The first is the Mauna Kea Spectroscopic Explorer (MSE), a proposed 10m telescope that would be devoted exclusively to wide-field spectroscopy at optical and infrared wavelengths -- the largest and most powerful facility of its kind ever devised. The second project, CASTOR, is a proposed wide-field space telescope that would rival NASA's Hubble Space Telescope in image quality, but cover a field of view roughly two hundred times larger. ”

Dr. Sara Ellison: Galaxy Mergers in the Nearby Universe

Dr. Sara Ellison

Dr. Sara Ellison

At 7:30 PM, 11 September 2015, at the Sunshine Coast Art Centre, 5714 Medusa St., Sechelt, our speaker for the Sunshine Coast Centre of the RASC will be Dr. Sara Ellison, Professor at the University of Victoria.

Dr. Ellison’s Topic will be “Galaxy Mergers in the Nearby Universe”:

Despite the emptiness of space, mergers between galaxies are surprisingly common. Around 1% of galaxies in the nearby Universe are currently experiencing an interaction of some kind.   will describe research that uses both observations and computer simulations to trace the dramatic effect of these interactions on a galaxy’s history: how the interaction can lead to massive bursts of star formation, alter the interstellar chemistry and even provide fuel for the central super-massive black hole.

Donations are gratefully accepted at the door.

May 2015 Speaker: Dr. Levon Pogosian

levon Pogosian

Dr. Levon Pogosian from Simon Fraser University will be speaking at the Sunshine Coast Arts Centre at 5714 Medusa St, Sechelt, at 7:30 PM on 8 May, 2015. His topic will be “From Static to Expanding to Accelerating: the past 100 years and the next 20”. Not only the universe is expanding, it is doing so at an accelerating rate. The physics causing the acceleration is currently unknown, but upcoming astronomical surveys of large scale structure will dramatically improve our ability to narrow the pool of possibilities. The lecture will review the history leading to the astounding discovery of cosmic acceleration in 1998 and the challenges that cosmologists are addressing today.
