Hi Henry,

Well, we've got lots of exciting data about galaxies far far away which are helping us understand  how the Universe was formed. The SPT can see all the way back to 300,000 years after the Universe was created.  When we go outside during the summer it only takes a few minutes to put on our clothes, however, in the winter we have to make sure that we have no skin exposed to the weather otherwise we get frostbite very quickly - That can take a good ten minutes.
