Spectroscopic data on alkali-atom dimers residing on the surface of liquid helium nanodroplets have revealed that they are detected primarily in the weakly bound, metastable, spin-triplet state. Here, ...

The cloud, named Eos, is chock-full of molecular hydrogen and possibly rife with star-forming potential in the future.

Conventional helium production comes with enormous carbon emissions, so scientists are looking for alternatives in places ...
