First look at Gravitational Dance that drives Stellar Formation

The four dark, filamentary arms are clearly visible. Right: Brand new, high resolution map of SDC13 tracing the internal dense ammonia gas revealing cores dotted along all the filaments. Credit: G.

Swirling motions in clouds of cold, dense gas have given, for the first time, an active insight into how gravity creates the compact cores from which stars form in the interstellar medium...
