Like character actors and perpetual opening acts, some interstellar gas clouds never quite become stars. Astronomers have substantially expanded the number of these elusive clouds known to exist near hot star-forming regions in the Milky Way.

Stars form when enormous gas clouds collapse under their own gravity and hydrogen atoms begin fusing into helium. But without fusion’s heat, galactic clouds are cold and sparse, and are difficult to find.

Seeking cold gas clumps, a team led by astrophysici...
