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 Perseus, the object is one of the youngest and nearest protostellar outflows, making it an ideal target for Webb.
Herbig-Haro objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars formcolliding with nearby gas and dust at high speeds.
This image of HH 211 from NASA's James Webb Space Telescope reveals an outflow from a Class 0 protostar, an infantile analog of our sun when it was no more than a few tens of thousands of years old and with a mass only 8% of the present-day sun. and their outflows, because such stars are invariably still embedded within the gas from the molecular cloud in which they formed.
