NASA says it has further evidence that Jupiter’s moon Europa is expelling large plumes of water into space. <br /><br /> If real, the jets might make it easier to find out if microbial life exists beyond earth. <br /><br /> The discovery was made using the Hubble Space Telescope. <br /><br /> Using Jupiter as a giant torch, astronomers observed Europa in silhouette through ultra-violet light, detecting what appeared to be water plumes. <br /><br /> They are thought to originate from the salty ocean which exists beneath the moon’s icy shell. <br /><br /> NASA scientists say flying through the jets with instrumented spacecraft to try to find life would present a much easier challenge than drilling through Europa’s ice to test the water. <br /><br /> Europa is about 3000 kilometres in diameter, slightly smaller than Earth’s moon, but one of the most active bodies in the solar system.<br />
