Here it is, several thousand years in the making: the protostellar jet HH212 as seen in the infrared by #JWST.
We discovered this jet in 1993, glowing in the light of shocked molecular hydrogen at 2.12 microns, as gas emerges symmetrically at about 100 km/s from the two poles of a young protostar not far from the Horsehead Nebula in Orion.
Our new JWST image spans six wavelengths & is ten times sharper than any previous infrared image.
