Plumes of water vapour 100 miles high may have been spotted bursting out of the icy surface of Jupiter’s moon, Europa.
Scientists believe they detected two vapour jets shooting into space for seven hours at a time.
Like “Old Faithful”, the volcanic geyser in Yellowstone National Park, the plumes appear to erupt at regular intervals. But while Old Faithful manages around 100 feet, Europa’s vapour fountains are thought to reach 124 miles.
If confirmed, the observations prove that water from the moon’s ice-covered ocean can easily reach the surface, which has important implications for future space missions. Many experts believe the hidden ocean surrounding Europa, warmed by powerful tidal forces caused by Jupiter’s gravity, may have conditions favourable to life.
Scientists used images from the Hubble Space Telescope to identify unusual “spikes” of hydrogen and oxygen in two distinct regions of the moon’s southern hemisphere.
