When it was completed in 1935, it was the second largest astronomical telescope in the world. The 74 inch reflector was used by astronomer Dr. Tom Bolton to confirm the existence of Cygnus X-1 as a Black Hole, a first in astronomy. Dr. Helen Sawyer Hogg contributed to our understanding of the universe by the decades of research at the David Dunlap Observatory’s mighty telescope. The 190 acres of surrounding undeveloped land are home to deer and over dozens of species of birds. It’s an oasis of astronomy and biology surrounded by the suburbs of Toronto.
The University of Toronto intends to sell the DDO and the surrounding wild space and fetch as much as $100 million dollars in the process. Will we see it snapped up by developers keen on turning the land into houses, offices and strip plazas? I hope not. There’s a strong community voice in Richmond Hill, including Mayor Dave Barrow who wants to see the site preserved. Local government along with community groups such as the Richmond Hill Naturalists have mounted a campaign to offer the U of T a serious alternative to the dismantling and destruction of the DDO. We know that this is the right thing to do. The David Dunlap Observatory represents a major piece of the history of astronomy, as well as the history of Canada.
We can do our part to help but we must act quickly. The University of Toronto has placed a deadline of February 15th, 2008 to decide on submissions for the sale of the facility. Let them know that you want the DDO to remain as a testament to the advancement of the science of astronomy, a part of our heritage and that it should be preserved. Take a moment and fill out this online petition.
Thank you and clear skies!

Well it’s been a while and we’re still catching up. In the summer, News in Space went to Starfest, one of the top Star Parties and Astronomy Conventions in North America. Very soon we will have a series of Starfest episodes posted on AstroShorts. I know many of you have been waiting patiently and you will be rewarded. Starfest attracts over 900 astronomy enthusiasts to Southern Ontario, Canada each year. Its diversity of programs means there is something for everyone. I’m impressed by how such a small group of organizers, the North York Astronomical Association produces such a great event.

The David Dunlap Observatory was one of the world’s leading facilities in Astronomical Research. Situated in Richmond Hill, just north of Toronto, it provided Canadian researchers the ability to explore the universe since the 1930’s. A lot of real scientific discovery went on at the 74 inch reflector telescope, once considered a Goliath. Now, it is a victim of progress. Light pollution from urban growth coupled with more advanced and more capable designs made the DDO less and less important. It’s hard to justify spending $800,000 per year to operate something that now offers minimal returns. The shame here is that we could have had gone further with the present facility if the political will existed on all levels of government to use better municipal lighting. Still, it had to happen eventually.
The facility was a gift to the University of Toronto from Jessie Dunlap in memory of her husband. The university recently announced that it has reached an agreement with the grandchildren of Jessie and David which allows the closure of the facility and sale of the lands and equipment. A new facility built with the proceeds will be called the Dunlap Institute. It will support future astronomical research from the U of T’s St. George Campus. Final vote is expected in October.
It is sad that this jewel will go missing from Richmond Hill. A piece of history will be lost. Progress is like that though; some good with the bad.

It really makes me happy to see the ever-increasing number of visitors to AstroShorts but that is only one part of the equation. It is the input of our members that makes a difference. I bet you’ve noticed more than a few videos from AstroShorts member John Crilly who takes some fabulous pictures from his urban observatory. I urge you to explore them all. Thanks John for all your valuable contributions.
I’m equally pleased to report that the good people at Astronomy magazine have posted a series of videos on a wide range of topics related to astronomy. There’s been a great deal of interest from viewers -they’re very popular and we’re really happy to see them available to AstroShorts viewers.
You can upload your own videos too! Don’t be shy. Everyone visiting AstroShorts wants to see. The whole astronomical community benefits every time someone shares their interest of astronomy. That’s why we are here, doing what we do and why you are visiting right now.
The day after the shuttle launch, the good folk of the Brevard Astronomical Society and Melbourne Astronomical Society were engaged in a public event to share views of the sun and other celestial objects. They are wonderful people who really do a great job of bringing the wonder and excitement of astronomy to people of all ages. It was a pleasure to speak with the individual members -we’ll have it all in an upcoming installment of “News In Space”. Of course, we shot some great video at the BCC Planetarium as well. They run many good programs and exhibits from their beautiful location on the Brevard Community College Campus.
We are working on four new episodes of “News In Space” which focus on Florida’s Spacecoast, including the BAS, BCC Planetarium and of course the Kennedy Space Center. I think you’ll enjoy them. If you are visiting that part of Florida, check them out.
