Laboratory built 8000' below Antarctic ice

The IceCube Observatory is a specialty lab constructed about a mile and a half below Antarctic ice. The South Pole lab was designed to observe Neutrinos which could hold important clues to the formation of our Universe (and Galaxy->Solar System->Planet). The $279M project was primarily funded by a $242M grant from the National Science Foundation.

From the article:

The collision between a neutrino and an atom produces particles known as ‘muons’ in a flash of blue light called ‘Cherenkov radiation’. In the ultratransparency of the Antarctic ice, IceCube’s optical sensors detect this blue light.
