A cosmic cherry on top 🍒
NASAWebb treated us to a sweet perspective: Herbig-Haro 49/50—a towering swirl from a nearby protostar—is (coincidentally) topped with a multi-hued spiral galaxy.
Herbig-Haro objects are outflows produced by jets launched from a nearby, forming star. The outflows, which can extend for light-years, plow into a denser region of material. This creates shock waves, heating the material to higher temperatures. The material then cools by emitting light at visible and infrared wavelengths.
The galaxy that appears, by chance, at the tip of this cosmic soft-serve is a much more distant, face-on spiral galaxy. It has a prominent central bulge represented in blue, filled with older stars. The bulge also shows hints of “side lobes,” suggesting that this could be a barred spiral galaxy. Reddish clumps within the spiral arms show the locations of warm dust and groups of forming stars.
