Astronomers have found a nascent star 750 light years from earth that shoots colossal jets of water -- a cosmic fire hose -- out its poles in bullet-like pulses. In a process that almost defies adjectives and analogies, each jet of water is the equivalent of a hundred million times the water flowing through the Amazon River every second and the speed of the jet is the equivalent of 80 times the muzzle velocity of an AK-47 assault rifle. The blast creates huge shockwaves around the star and the process may be responsible for sprinkling the universe with water. And it could go on for a thousand years in each star. Astronomers think all baby stars go through this process as they form, and that our sun did it too once. link

Baby star blasts jets of water into space
