of the island is mostly villages, and so there's almost no light pollution. and so that's where you really get to see the incredible skies. one of the best stargazing spots on the islands can be found an hour down the road at gallan head. it was an raf base during the cold war, and now it's where the festival takes people to observe and photograph the night sky. well, this is andy. andy! so we've got andrew and andy. you've done this on purpose, haven't you? we have. just to confuse you. what is it about seeing galaxies and seeing stars...? 0h, theyjust... well, galaxies in particular, they're so far away, you know, you're looking back in time. one of our nearest galaxies, the andromeda, it's 2.5 million light years away. it's like a moment in time, isn't it? and this area is particularly good for seeing the planets?
