Scientists strongly believe there is an ocean hidden under the ice surface of Europa . The Hubble Space Telescope captured a spectrographic image showing water vapor . Astronomers believe it came from a geyser connected to the hidden ocean . The vapor could make it possible for a space probe to analyze the water for signs of life .
