Playing With Liquid Helium At The South Pole Cryogenics Lab

To support the various telescopes and experiments here at the south pole, a ton of resources are necessary – power, heating, environmental protection, and somewhat counterintuitively, cooling. Some of the telescopes here are so sensitive, and looking at such distant signals, that in order to work properly they need to be cryogenically cooled down to …
