Fri May 23 – 8 pm Gas Falling Into Black Holes: A Surprising Discovery

dec10PatHallPhoto[1]Gas Falling Into Black Holes: A Surprising Discovery

Pat Hall from York University will be our speaker.

A black holes is inferred to exist at the center of every massive galaxy, including our own Milky Way. We cannot see such a black hole directly, but we can see light from hot gas orbiting the black hole.

This gas forms a disk larger than the Earth’s orbit around the Sun and hotter than the surface of the Sun, putting out enough light to be seen across the universe; we call this light a quasar.

For 45 years we have known that some quasars have part of their light absorbed by gas streaming AWAY from the black holes, in winds lifted from the surface of these disks. A few years ago, I discovered some cases of absorption which may come from gas streaming INTO the black holes.  But it may be difficult to explain the speeds at which the gas appears to be falling into the black holes in these quasars; they may instead be cases of winds in systems with two black holes orbiting each other!

Tues May 6 9pm – Riverwood Observing Night

Observe the Moon and planets through large telescopes

Come out and observe the universe at the Riverwood Conservancy! Join members of the Mississauga Centre of the Royal Astronomical Society of Canada as they set up large telescopes to look at the Moon, planets and stars. Observing will take place on the green in front of Chappelle House. The event starts at dusk is free and open to everyone.

Large telescopes will be set up and pointed at the Moon, the planets Jupiter, Saturn and Mars and other objects beyond our solar system.

Look for meteors, artificial satellites and anything else in the skies over Mississauga.

Note: If the weather is cloudy, the observing will be delayed one day. Check this web site for GO/NO GO information on the afternoon of the 06th.

The weather looks good for tomorrow night. It might be a little cool so dress warmly. We should have great views of the Moon and three planets – Jupiter, Mars and my favourite – Saturn!

RASC GENERAL ASSEMBLY

2014_GA_Logo[1]

June 26th – June 29th 2014

Join the members of Victoria Centre as we commemorate 100 years of being a RASC Centre at our 2014 RASC General Assembly. To add to the festivities, we will also be celebrating the 100th anniversary of the Dominion Astrophysical Observatory, located in Saanich B.C., just to the north of downtown Victoria.

The 2014 General Assembly will showcase the DAO, the University of Victoria’s new observatory located on the campus of our assembly’s headquarters and a wide-ranging scientific and cultural schedule of events for your family, all conducted against the spectacular natural beauty of Canada’s West Coast. Guest Speakers include Dr Laura Ferrarese,  Bob McDonald of CBC’s Quirks and Quarks, and RASC’s own Peter Broughton.

Victoria is serviced by both of our domestic air carriers and can be reached by convenient car ferry service connecting Victoria to Vancouver and Seattle, Washington.

From on-campus accommodation at the University of Victoria to nearby hotel and RV facilities, there are many lodging options available in the Greater Victoria for RASC members.

Registration https://www.rasc.ca/events/home

Please join us in Victoria June 26 – June 29, 2014!

Fri Apr 25 – 8 pm Ultra-low Surface Brightness Imaging with Project Dragonfly

Roberto_abraham[1]Ultra-low Surface Brightness Imaging with Project Dragonfly

Dr. Roberto Abraham will describe early results from Project Dragonfly, a Toronto/Yale instrument concept whose goal is to open up the new observational regime of ultra low surface brightness astronomy at visible wavelengths. Its design is optimized for testing the most fundamental prediction of galaxy formation models, namely that at low surface brightness levels all galaxies are embedded within a sea of complex substructure.
The project couples innovative observing techniques (multiple redundant unobstructed beam paths and real-time modeling of sky variations for precision control of systematics) with new technologies, such as sub-wavelength nano-fabricated optical coatings to minimize scattered light and ghosting.

Dr. Abraham is a Professor in the Department of Astronomy & Astrophysics at the University of Toronto. He is also the Associate Chair for Graduate Studies in the department.

Fri Feb 21 – 8 pm Searching for Water Across the Solar System

WaterInTheSolarSystem
Searching for Water Across the Solar System

Abstract: In our exploration of the solar system, the most repeated motto might be “Follow the Water.” What does this mean in a planetary context and why are we so interested in such a common molecule? This talk will describe where the solar system’s water originated, how it was distributed and what that has meant for the evolution of the planets and of smaller bodies.

Particular emphasis will be placed on the changing environment of Mars and how a planet with a warm and wet past became the cold and arid world we know today. The environments of the icy moons of the outer solar system will also be discussed. Here, our search for water is a search for pockets of liquid in a sea of stony ice. It is the observations described by planetary spacecraft that unite these twin quests. However, at the root of it all is a desire to know ourselves and our own world a little bit better.
Dr. Moores is an Assistant Professor at York University in Toronto, Canada. He is the recipient of three NASA Group Achievement Awards and has published 25 peer-reviewed papers on Planetary Science. It was during John’s undergraduate work in Aerospace Engineering at the University of Toronto that he realized that his true passion lay in exploring other worlds.

Following receipt of his B.A.Sc., this brought him to the Lunar and Planetary Laboratory at the University of Arizona, where he earned his PhD working for Peter Smith on planetary atmospheres. During this time, he was a participant on several space missions including the Phoenix Mars Mission and the Huygens mission to Titan.

Since graduating, John has held research positions with Environment Canada and the Centre for Planetary Science and Exploration at the University of Western Ontario. He is presently a Participating Scientist with theMars Science Laboratory.
