Infrared Capabilities Map Out Molecular Structure of Outflow NASA’s James Webb Space Telescope has captured a high-resolution look at Herbig-Haro 211 (HH 211), a bipolar jet traveling through interstellar space at supersonic speeds. At roughly 1,000 light-years away from Earth in the constellation
NASA’s James Webb Space Telescope captured HH 211, a Herbig-Haro object, revealing detailed outflows from a young protostar resembling an early Sun. The high-resolution image suggests a possible binary star system, and studies show outflows composed mainly of intact molecules due to low-energy shock waves.

NASA’s James Webb Space Telescope’s high resolution, near-infrared look at Herbig-Haro 211 reveals exquisite detail of the outflow of a young star, an infantile analogue of our Sun. Herbig-Haro objects are formed when stellar winds or jets of gas spewing from newborn stars form shock waves colliding with nearby gas and dust at high speeds. The image showcases a series of bow shocks to the southeast and northwest as well as the narrow bipolar jet that powers them in unprecedented detail.
The team measured the velocities of the innermost outflow structures to be roughly 48-60 miles per second . However, the difference in velocity between these sections of the outflow and the leading material they’re colliding with — the shock wave — is much smaller.
