Seven Canadian universities, including Western, have joined as partners in the Cerro Chajnantor Atacama Telescope (CCAT) project, a proposed 25-meter aperture telescope that will be built in Chile.It will become the largest, most precise and highest astronomical facility of its kind in the world.
Started as a project between Cornell University and the California Institute of Technology in 2004, the partnership extended to include the University of Colorado at Boulder, the universities of Cologne and Bonn in Germany, and Associated Universities Inc. of Washington, D.C. Now seven Canadian universities from four provinces have joined in as part of a consortium that also includes British Columbia, Calgary, McGill, McMaster, Toronto, and Waterloo.
"This is a general purpose telescope that will be used to explore the cosmic origins of the early universe," says Waterloo Professor Mike Fich, who is the Canadian lead for the project. The telescope captures wide views of submillimetre electromagnetic wave emission from space, and can do so with unprecedented speed and resolution.
"Our modern conception of the universe is that it was all created about 14 billion years ago, and that the universe soon after managed to create the basic elements like carbon and oxygen from which we are made" says Professor Shantanu Basu, Chair of the Department of Physics and Astronomy at Western. "The CCAT telescope can allow us to peer back in time to that era, some 10 to 12 billion years ago."
The $140 million project was strongly endorsed by the Committee for a Decadal Survey of Astronomy and Astrophysics of the U.S. National Research Council. The Committee also recommended that the National Science Foundation contribute one-third of the construction cost of the facility. The project is expected to be completed in 2017.

There has now been official confirmation of the discovery of three new asteroids by Amanda Papadimos. The discoveries took place when Amanda was working with Dr. Paul Wiegert but confirmation can take some time. Amanda is presently working in the Planetary Science and Space Exploration group.
The asteroids are named as follows:
Asteroid 2004 VR122 now officially asteroid number 254422
Asteroid 2006 UJ349 now officially asteroid number 262536
Asteroid 2008 AA119 now officially asteroid number 263251
The orbits of these objects can be seen by going to this NASA small object database and entering the asteroid number in the search engine.

Dr. Eduard Vorobyov (Visiting Scientist -shown at left) and Prof. Shantanu Basu of the Department of Physics and Astronomy have performed computer simulations that trace for the first time the collapse of a nebular cloud all the way to the formation of a star-planet system. Angular momentum of the cloud leads to the formation of a disk of material around a newly formed star. In situations where the disk is sufficiently massive, a fragment in the disk can form and then open up a gap in the disk, allowing a protoplanet to survive in a stable orbit. The results published in Astrophysical Journal Letters (2010, 714, L133) and ongoing work reveal that the formation of multiple star systems and planetary companions, while not predictable exactly in a deterministic fashion, are strongly dependent on the properties of the initial nebular cloud.

A celebration was held on Monday, October 25, 2010 to mark the 70th anniversary of the opening of the Hume Cronyn Memorial Observatory here on the campus.
The idea for this birthday party was that of Amanda Papadimos, whose efforts also brought it to fruition.
Amanda presented a brief history of the observatory after which everyone enjoyed some cake and interesting conversation with topics ranging from the history of the building, the public astronomy program, to the Dresden Meteor plaster cast which had been on display for many years.
The formal proceedings ended with department chair Shantanu Basu reading words of congratulations from James Hesser, director of the Dominion Astrophysical Observatory in Victoria, which is part of the Herzberg Institute of Astrophyics in the National Research Council.
Hume Blake Cronyn, for whom the observatory was dedicated by his wife Francis Amelia Labatt Cronyn, was instrumental in founding the National Research Institute, which was the predecessor of the National Research Council of Canada.
Finally, Peter Jedicke, honourary president of the London chapter of the Royal Astronomical Society of Canada (RASC) gave words of wishes on behalf of not only the local chapter, but extended well wishes on behalf of RASC members across the country by president Mary Lou Whitehorn.

On Friday August 6th 2010 a group of Native Canadian children from all over Canada and various reservations visited Prof. Silvia Mittler and her research group for an introductory session to OPTICS and PHOTONICS.
The event was part of a weeklong scientific travel and information experience for 50 youth aged 12-15, and was organized by the NATIONAL SCIENCE CAMP of INAC (Ministry of Indian and Northern Affairs Canada).
The event at Prof. Mittler's lab was aided by CIPI and OCE. David Doran ( of CIPI) brought the new “CIPI OPTICS and PHOTONICS hands-on and demonstration suitcase”. Accomanying David was Jessie Maggard, the London based Business Development Manager of OCE. In addition, Andreas Schönfeld, a German DAAD undergraduate summer exchange student, PhD student Erden Ertorer, and PDF Ireneus Iwanowski) of the Mittler group were present during the event and assisted with the scientific demonstrations, explanations and the hands-on experiences.
After the children had returned from a visit to Sarnia and the Sarnia local industry, they were welcomed in the Physics and Astronomy First Year Laboratory in the Material Science Addition. They were introduced to “What is Light: It is an Electro-Magnetic Wave and a Photon” by way of a power point presentation by Prof. Mittler, followed by some experimental demonstrations supporting the theoretical explanations.
The group was then split into two parts. One group stayed in the First Year lab and had hands on experiences with 5 different experiments, while the other group enjoyed a lab tour into Prof. Mittler’s Laboratory for Photonics of Surfaces and Interfaces in the Physics and Astronomy Building. Both the optics lab and a sample preparation-chemistry lab were shown, and a quick insight in modern interdisciplinary optics and photonics research given. The highlight of the lab tour was the opportunity to work with a real high-tech clean room glove box.
