This element was first observed by Jules Janssen during the solar eclipse of 1868. It can be used to detect small leaks in high pressure containers, but its most common application involves cooling superconducting magnets in MRI scanners. As temperature approaches absolute zero, this substance forms a Rollin film, enabling it to creep along surfaces as a (*) superfluid. It's also mixed with nitrogen and oxygen as a breathing gas for deep-sea divers, and because sound propagates faster in gases with low molecular weights, inhaling this gas can increase the pitch of one's voice. For ten points, name this noble gas, the second most abundant element in the universe, which has an atomic number of 2 and chemical symbol He.
