Europa

Scientists have found evidence of a liquid water ocean swirling under the icy shell of Jupiter’s moon Europa, Nasa announced on Monday, with new evidence of water plumes bursting out into space. Scientists first reported the behaviour in 2013 using the Hubble telescope, but have now made a follow-up sighting.

Experts confirmed that the skeletal remains found in a tomb in Vergina, northern Greece, belong to King Philip II of Macedon, Alexander the Great’s father. The royal father suffered a leg wound that left him crippled three years before his assassination in 336 BC. New research found evidence of his injury and signs of lameness in the skeletal remains.
