Using the Hubble Space Telescope, astronomers have witnessed an infant star 20 times larger than the sun setting interstellar clouds ablaze. The source of this cosmic conflagration is a stellar jet travelling at an incredible 2.2 million miles per hour (3.5 million kilometers per hour), the fastest outflow of this type ever seen.
This particular outflow is also the longest outflow from a forming star or protostar ever seen by astronomers, stretching out for a staggering 32 light-years. For context, that is around 8 to 10 times as wide as our entire solar system.
