Research led by Durham University studied a lunar volcanic eruption . The team found that the eruption was much bigger than was thought . It erupted 3.5 billion years ago and covered a UK-sized area in debris . This was thanks to the low gravity of the moon . The same 'mapping ' technique will be used for Olympus Mons on Mars .
