I’m blogging today over at Contact — Infinite Futures about superfluids possibly forming in the core of Cassiopeia A:

Scientists recently came one step closer to confirming the existence of neutrino superfluids after examining changes in the heart of the 330-year-old supernova remnant Cassiopeia A. The leftovers of exploded stars, the core of a neutron star is so dense that atomic nuclei dissolve. Then all those itty bitty quantum parts are up for grabs. What happens then?

Come find out how we might use this substance in science fiction and in real life.
