Nov 27 (This Friday): Dr. Ernie Seaquist – Canada’s engagement in the new “World Observatories”

Seaquister.jpgThe November 27th meeting of the RASC Mississauga Centre will feature a talk on Canada’s involvement in the development and use of new large telescopes.

In recent years Canada has become part of the international club participating in a series of what we might call “World Observatories”. These are astronomy facilities which are unique, or nearly so, and which are sufficiently costly ($1B or more) that they are affordable only by relatively large international consortia.

Examples are the Atacama Large Millimeter Array (ALMA), and the forthcoming facilities: the James Webb Space Telescope (JWST), the Thirty Meter Telescope (TMT), and the Square Kilometre Array (SKA). Canada is participating at some level in all of these.

Ernie will discuss the impact of these projects on Canadian astronomy and on our understanding of the universe and its origins. Ernie will also touch on the economic benefits and the politics, both national and international, underlying the achievement of membership in such partnerships. Of particular interest is whether engagement in such large projects leaves any room for smaller and less expensive national initiatives. Another important topic is the role of the RASC in this new era, and an examination of the mutual benefits of the current initiatives to both professional and amateur astronomers.

Ernie is Professor Emeritus at the Department of Astronomy and Astrophysics, University of Toronto. Until his retirement in 2004 his field of research was radio astronomy with emphasis on star formation in starburst galaxies and radio emission from active stars. He was Chair of the Department and Director of the David Dunlap Observatory between 1988 and 1999. Since retirement he has been involved various aspects of Canada’s engagement in the TMT and the SKA. He is currently Executive Director of the Association of Canadian Universities for Research in Astronomy (ACURA), the organization responsible for spearheading the successful effort to get funding for Canada’s role in TMT. He is also a member of the Board of Governors of the TMT International Observatory (TIO) which owns the TMT and will oversee the construction and ultimately its operation.

The meeting will be held from 8:00 to 10:00 p.m. at The University of Toronto,Mississauga Campus, in lecture hall SE2082 in the William Davis Building. The meeting is open to the public and is free.

Riverwood Tues Nov 17th 7:00PM – It’s a GO

Oct 30: Professor Paul Delaney, York University

Dwarf Planet Revealed: New Horizons at Pluto

The search for Pluto started in 1781 with the confirmed observation of Uranus.

It took until 1930 for an astronomer to find the “9th planet.”  Little did Clyde Tombaugh know the excitement his discovery would generate in the 21st century.  However, the secrets of the last of the “classical planets” would not be revealed until the fly by of the New Horizons spacecraft in July 2015.  This lecture will summarize the history of Pluto and the results sent back to date from New Horizons.  The revelations are unexpected!

Professor Paul Delaney

 

Paul Delaney is a senior lecturer and professor of physics and astronomy at York University in Toronto. He is also the director of the Division of Natural Science within the Faculty of Science at York, as well as the Master of Bethune College at York.

Delaney has his Master’s degree in science. He has taught at York University since 1986. He earned his Bachelors in Science in Experimental Physics at the Australian National University in Canberra and his Master’s degree in astronomy at the University of Victoria. Delaney has been the recipient of many faculty of science and engineering awards at York University. One of his classes deals with the possibility of life on Mars. Delaney is also the director of the observatory at the York University, and its outreach program. In the past, he has also worked as a nuclear physicist at the Atomic Energy of Canada, and a support astronomer with the McGraw-Hill Observatory in TucsonArizona.

Sept. 25th: Ivan Semeniuk –

Over four fifths of the matter in the universe is an unseen, unidentified substance known as dark matter. Astronomers posited the existence of dark matter in the 20th century but discovering its true nature had become a key goal for experimental physicists in the 21 Century. Scientists are now closing in on the elusive stuff with major experiments underway on three fronts — in space, in deep underground laboratories and in the heart of the world’s largest particle accelerator. The coming 18 month are expected to be crucial because it is a period during which dark matter with either be found or a wide range of possible explanations for it will be ruled out.

Starfest was a lot of fun

Starfest was a wonderful weekend for those interested in astronomy to observe together, listen to illuminating lectures, and get to know their fellow Centre members better. There were over 35 members from Mississauga attending. Skies varied from really good (Wednesday), through clear with poor transparency and seeing to fog-bound. Evenings were spent observing through telescopes both large and small, learning something new about the night sky or just visiting back and forth.

A big thank you to David Mitchell and his family for the lovely supper and breakfast Chez Rikki.
