One of the more surreal aspects of JWST images is that infrared light can pass through a lot of dust and gas, allowing us to see galaxies that were previously hidden. New images of Herbig-Haro 49/50 resemble a weirdly abstract Christmas tree; a ring galaxy ornaments the end of the jet as other systems peer out through the nebulosity. The clouds we see are formed where a young star’s jet pushes the interstellar media. This is just a chance alignment, but sometimes random chance can produce something really cool to look at.
