This stellar glowing jet is from a young star
NASA's Hubble space telescope has captured an image of HH 151, a bright jet of glowing material trailed by an intricate, orange-hued plume of gas and dust.
The star is located some 460 light-years away in the constellation of Taurus (The Bull), near to the young, tumultuous star HL Tau.
In the first few hundred thousand years of life, new stars like HL Tau typically pull in material that falls towards them from the surrounding space. This material forms a hot disc that swirls around the coalescing body, launching narrow streams of material from its poles.
These jets are shot out at speeds of several hundred kilometers (or miles) per second and collide violently with nearby clumps of dust and gas, creating wispy, billowing structures known as Herbig-Haro objects — like HH 151 seen in the image above.
Such objects are very common in star-forming regions. They are short-lived, and their motion and evolution can actually be seen over very short timescales, on the order of years, in fact.
They then quickly race away from the newly-forming star that emitted them, colliding with new clumps of material and glowing brightly before fading away.
