Scientists have confirmed to discover an ocean beneath the icy surface of Jupiter’s largest moon Ganymede. The ocean sits under a 95-mile-thick sheet of ice and the scientists added that its depth is estimated to be 60 miles. All along this has been a suspicion which will no longer be after the use of Hubble Space Telescope which revealed the evidence. It is expected that these finding will bring to an end a mystery about Jupiter which is said to be the largest moon within the solar system. The researchers used the data collected from the Telescope to measure the motions of auroras that occurred as a result of the moon’s magnetic field.
