The Spitzer Space Telescope captured this baby star burping at speeds of 600,000 mph, give or take. Most of the emission is simple hydrogen, but the red spots at the end of each filament are gaseous sulfur and iron impacting the interstellar gas and dust near HH46/47. No worries about any projectile gas coming our way; this event is 6.7 quadrillion miles distant. In other words, if the nearest star were in your backyard, HH46/47 would be over a mile away.
