A new study suggests there is less oxygen on the icy surface of Jupiter's moon Europa than scientists previously thought.

Europa, one of Jupiter's 95 moons, generates 1,000 tons of oxygen every 24 hours, NASA's Jet Propulsion Laboratory said Monday. It's enough oxygen to keep a million humans breathing each day, but it's substantially less than scientists previously believed existed, researchers said. The amount of oxygen could impact the moon's underground ocean, which is thought to contain twice as much water as all of Earth's oceans combined.

'Though the planet has oxygen, it wouldn't necessarily be a safe place for humans — and not just because of a lack of breathable air.'The question of human exploration at Europa is a very complex one,' Szalay said in an email. 'The radiation is extremely intense at Europa and estimates suggest an astronaut within a space suit would not be able to survive more than a day on the surface solely due to this intense radiation.
