The Burke-Gaffney Observatory – Cosmoboy’s unveiling speech

11 11 2014

Ecogirl suggested that I post my speech from the press conference – so here it is!

speech“Thank you everyone for being here for this celebration!

While our Observatory Director Dave Lane is going to tell you about the Medjuck telescope and our plans for the Burke-Gaffney Observatory in detail, I just want to take a couple of minutes of your time to talk about the impact of astronomy on campus.

Everything you are is a product of your experiences and choices.

And a great education informs both of these; by exposing you to new – sometimes breathtaking – experiences, and providing you with the knowledge and frameworks you need to make good choices.

press_confThose thoughts are really what drove the renovation of the Burke-Gaffney Observatory. Any student that studies astronomy, whether in introductory courses for non-scientists or the more specialized honours program, will have a chance to use the Medjuck telescope for observing projects. Thanks to our enthusiastic telescope operators you don’t even have to know your eyepiece from your elbow to be able to use the telescope!

laneBut even more exciting is the possibility of robotic control. Dave Lane has done a remarkable job in bringing the observatory up-to-date. He can now control it entirely from home, and as you’ll see today, a social media interface is in the works. Need to get a picture of a galaxy for your ASTR1000 project? Try tweeting.

But access alone isn’t the most amazing thing about the renovation. The gorgeous new 24.5 inch Medjuck telescope is the second largest campus telescope in Canada. With a modern optical design it produces stunning images, significantly better than our beloved Ealing telescope. It is a fantastic piece of research grade equipment – indeed a model just like it has been cold tested for deployment in the Arctic. We know it works down to -35 C, so I guarantee we’ll still be running in the middle of winter!

But to give you an idea of its capabilities, just a day before one of the first viewing sessions with the new telescope, a supernova went off in a neighbouring galaxy (and for those of you that don’t know, the first supernova ever discovered in Canada was discovered from the BGO in 1995). But how far away was that supernova? 11.5 million light years. To put that in context, the light from that supernova left before the great-apes had truly started evolving on the savannah of Africa. There were no humans anywhere.

I’ll leave it to the words of seven year old girl to describe what she thought of seeing the supernova and how old it was: “That’s soooo cool!!!

But this isn’t even close to pushing the limits of the Medjuck Telescope. The most distant object it will be able to see, the not very romantically called 3C273, is 2.5 billion light years away. The light that we are now receiving from it left when the only form of life on Earth was single cell bacteria. No plants. No higher forms of life. The fossil cliffs at Joggins were still 2.2 billion years from being formed.

Just think about this for a second:

BGOYou now have a chance to put light in your eye that has travelled across almost 20% of the entire Universe. To be influenced by something that is unimaginably distant, something incredibly old. That’s a breathtaking experience. It may not be full of heart pumping adrenaline, but it makes you realize something quite profound – that even the most distant of things can have an impact on how you see the world and yourself.

And by now you’ve also realized that astronomy isn’t just about charting the skies. It’s about time-travel too. You probably didn’t think of the Medjuck Telescope as a time-machine, but in some sense that’s exactly what it is.

medjuckAbove all this, we should see the chance to have these experiences, and the knowledge that comes with them, as a gift. Thanks to the generosity of Dr Medjuck the support of the University, and hard work by dedicated individuals, we’re incredibly excited and just a little bit proud in Astronomy and Physics to be able to share these experiences both with everyone on campus, and also the community of Halifax. And through social media, perhaps soon the world!

So please, come to the BGO and be amazed.

The Universe is yours to discover.

Thank you.”





The “All New!” Burke-Gaffney Observatory

1 11 2014

bgopreviewOver the past 18 months Cosmoboy has been honoured to be a part of the Burke-Gaffney Observatory renovations at Saint Mary’s University. Built in 1972 to honour Father Burke-Gaffney, it has become an icon of the Saint Mary’s campus. But in all that time it has never had significant renovations – beyond CCD upgrades – and much has changed in astronomy technology. By the time of the 40th anniversary it was clear that revitalization of the BGO was needed!

Plans were hatched by the Observatory Director Dave Lane and Cosmoboy in the fall of 2012. The ambitious renovation proposal included a new 24.5 inch telescope (from Planewave, their CDK24 model), and adding an observing deck so we could show more of the sky at a given time. That would also increase the student and visitor capacity of the observatory – we’ve had days when the queue went down the stairs… Which doesn’t make it much fun anyone.

Medjuck_familyThe University was supportive from the get-go, but budgets were tight and we were asking for significant funds. In the end, our Office of Advancement came to the rescue and through our President’s Office the well known local philanthropist Dr Ralph M. Medjuck was approached. As many people in town are aware, Dr Medjuck and his wife Mrs Shirlee Medjuck (right with their daughter Linda) have donated considerable sums to Halifax universities in support of education. To cut to the chase, Dr Medjuck agreed to support the project, and we named the telescope in his honour.

I’ve said thank you to our benefactors so many times already, but I can’t write this blog post without saying thanks again to Dr and Mrs Medjuck. Without their support, and that of Saint Mary’s University at large, this project would not have been possible.

bgo_titleBut cut to April 2013, things were moving forward. At that point we decided the project was a “sufficiently big deal” for the university and the department that we should make a short documentary on it. Local filmmaker and astronomy fan Martin Hellmich agreed to take the challenge on! The resulting film can be seen here – watch it in HD! There are some really fantastic time-lapses in there – we were pretty gobsmacked when Martin first showed them to us! Go watch it!

BGO_telescopePainting of the dome and mount happened during the summer of 2013 and turned out to be much more of an adventure than we had anticipated. To cut a long story short, you really need to prime well! But we all think the final look is great – the white of the pier matches the black and white of the Medjuck telescope perfectly, while the blue accents the small details on the ‘scope. Kudos to Dave Lane for picking out the colours! Note, the paint has to stand up to some tough conditions – the observatory gets brutally hot in the summer and cold in the winter (snow will often sneak into the dome through the gap between the rotating and stationary parts).

obsdeckFencing off the observatory deck also encountered a few glitches. The initial drilling was done at the end of exam time and understandably some complaints were made about the noise! So we held off finishing that until all the exams were done. But the end product looks great, and we all agree the view from 22 floors up is simply mind-blowing – especially at night! So if we get parents that aren’t too interested in astronomy bringing their children along to open houses, we still have something to take their breath away.

install_scopeOf course, the most fun part of the whole project was the new telescope arrival and installation! With a 6 month delivery time, we had our fingers crossed it would be delivered just before Christmas 2013 so that we could swap it in for the new term starting in January 2014. Everything went to plan. But installing a new telescope in the middle of December in Canada is a chilly proposition! So we had to borrow a 5kW heater to warm things up. The 40 year old mount bolts were just fine as well, despite us being very worried about the possibility of things breaking!

press_confAnd finally bringing the story up-to-date, this week (October 2014) we’ve been able to celebrate the installation and thank everyone involved! There’s still a lot of work to be done on the social media side, but the hardware is all in place. The press events this week went off fantastic, and some of our friends in the media did an awesome job of letting people in Halifax know about the renovations (here, here, here, here). We’re just over the Moon (sorry! 🙂 ) to have everything get to this point!

So please, if you’re in Halifax and want to take look, reserve a ticket and come to a public night! We’d love to see you there!
