Hubble spots a bright glow driven by a young massive star

Hubble discovered an extraordinary bright pink and green glow in the constellation Sagittarius, marking the first time astronomers have found Herbig-Haro objects powered by a young massive star rather than typical low-mass stars. The HH 80/81 objects stretch an unprecedented 32 light-years and feature gas jets moving at record speeds exceeding 1,000 kilometers per second, making them both the largest protostellar jets and fastest stellar outflows ever observed.
