Stellar sprinklers may help irrigate cosmos, study suggests.Seven hundred and fifty light-years from Earth, a young, sunlike star has been found with jets that blast epic quantities of water into interstellar space, shooting out droplets that move faster than a speeding bullet. The discovery suggests that protostars may be seeding the universe with water.
