A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this before—and it may help solve two outstanding cosmic mysteries. A paper describing these results is forthcoming in The Astrophysical Journal Letters and currently available on the arXiv preprint server.
