Ecogirl suggested that I post my speech from the press conference – so here it is!
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.
Those 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!
But 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:
You 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.
Above 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.
