Underwater archaeologists looking for buried treasures from an ancient shipwreck in Greece have completed their first 'spacewalk under the sea'. The high-tech 'Exosuit' is being used to explore the Antikythera shipwreck, and has allowed them to dive to more than double the depths of previous expeditions. It was on this location that the so-called Antikythera Mechanism - a 2nd-century BC device dubbed the world's oldest computer - was discovered by sponge divers in 1900 off the remote Greek island.
