Morning.

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.

@bert_hubert I’m on the World Service quite a lot – they take science quite seriously still – so I’ll take credit for the tiniest smidgeon of that increase 🤪
