'Thousands' of new ocean mountains
It is not every day you can announce the discovery of thousands of new mountains on Earth, but that is what a US-European research team has done. What is more, these peaks are all at least 1.5km high. The reason they have gone unrecognised until now is because they are at the bottom of the ocean. Dave Sandwell and colleagues used radar satellites to discern the mountains' presence under water and report their findings in Science Magazine.
