Listening to the Stars

Here's another photo from my summer holiday in the southern interior of British Columbia. This is the Dominion Radio Astrophysical Observatory at White Lake in the mountains above Penticton. There is no telescope. These huge dish antennae collect radio signals from space. Scientists have their reasons for doing this. You can read all about it HERE. I didn't see any aliens around the place but you can't get inside so who knows what's in there?
