A newly discovered structure located deep in the heart of a thick cloud of gas and dust more than 450 light-years away is the signature of a pair of baby stars in the throes of formation.
a stellar nursery called Barnard 18 in the Taurus molecular cloud complex, likely carved from the surrounding gas as two emerging stars therein formed and grew.
These outflows are called feedback, and they're thought to play an important role in cutting off protostellar growth, as well as the evolution of the interstellar medium – the gas and dust that drifts around in the spaces between the stars. Using two different radio telescopes, they analyzed the carbon monoxide signal, which can be used to trace structures within a cloud of gas. And, lurking within the Barnard 18 molecular cloud, they found evidence of a bubble structure.
