New observations from NASA’s Hubble Space Telescope suggest water vapor plumes are venting from Jupiter’s moon, Europa. The discovery was made on Europa’s south pole, which has previously shown evidence of water; the newest finding further hint that the moon is home to a hidden ocean under a thick layer of ice.

Scientists using the Hubble Space Telescope have found plumes of water vapor shooting off the southern pole of Europa, an ice-covered moon of Jupiter that is believed to have an underground ocean.
