I’m starstruck by this new #JWST image of one of my favorite astronomical objects 🤩

Herbig-Haro 46/47 is a pair of jets launched by young stars, embedded in a dark nebula.

The binary stars responsible for the jets shine brightly in the middle of the image, seen as one point of light with red diffraction spikes.

The two-sided orange lobes were created by earlier outflows. More recent ejections appear as a blue line in the center of the lobes.

A multi-wavelength view of HH 46/47. In visible light, we only see one jet. The other jet and the young stars are still embedded in a dusty nebula.

In JWST’s near-infrared view, we see through the dust, revealing what’s going on inside.

In ground-based near-IR, we don’t see the young stars, but we do see the ghostly outline of the nebula.

In Spitzer's far-IR view, the nebula disappears and we can see the stars and both jets.

With Alma, we see cold gas lighting up the edges of the cavity.

That is a complicated object!

I don't know if you're looking for requests or recommendations for the sort of "outreach" people like, but I'd love a 3-5 minute YouTube clip of an astronomer pointing out areas of that image and narrating what's happened to bring it about.

@jztusk I don't have a video like that ready, but I did help make an interactive, multi-wavelength slider about HH 46/47. Make sure the labels are turned on to see some important features of the object. Slide between stops to see it in different wavelengths. If you scroll down, there is also a longer description of the object.
