A Trillion Here, A Trillion There

HH-47 is a Herbig-Haro Object, a young star that is ejecting material at mind-bogglingly high speed (up to a million km/h) into its surroundings. The material glows as it impacts the surrounding gas, and the streamer from HH-47 is around five trillion km long. The star is about 1,400 light-years away.
