The lava flows that formed the Scottish Isle of Skye may have been triggered by a meteor impact, according to a study published in the journal Geology. Per the BBC, researchers found two minerals not found on Earth, but known to occur in meteors, embedded in rock located underneath layers of ancient lava. Right now it's unclear how large the meteor was, but study author Simon Drake tells BBC Radio Scotland they've found evidence of the strike in two separate locations, and possibly two more.
Why it matters: The Isle of Skye, and other features in that region, were formed when a large plume of lava rose from the ocean floor. It's possible a meteor triggered the plume, and may have influenced the geology of places as far away as Iceland and the Eastern part of Greenland.
