An image from the Webb Telescope shows outflow from a newly forming star, giving this Herbig-Haro object (HH 49/50) its nickname, the “cosmic tornado.” This pillar of gas and dust looks like it’s topped by a galaxy, but in reality the galaxy is light years away. Herbig-Haro objects are outflows produced by jets launched from a nearby, forming star (in this case, out of frame at lower right).

JWST NIRCam IR image of Herbig-Haro 211.

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.

HH 211, 1,000 ly away, is no more than a few 10,000 years old and has a mass only 8% of the present-day Sun (it will eventually grow into a star like the Sun).

We wonder why NASA uses the term "supersonic" to describe these ~100 km/s outflows in space.

#HH111 is a Herbig-Haro object, a bright patch of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionised gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometres per second.
