UFOs are having a renaissance lately, moving beyond the tinfoil-hatted crowd and into the realm of serious government investigation. Now a study has analyzed the geography of almost 100,000 sightings and found a few clues about how they cluster.

Scientists have found a massive area the size of 1.5 football fields, now dubbed "The Coliseum," which was once a popular thoroughfare to water for multiple species of prehistoric beasts over many generations some 70 million years ago.

New modeling from researchers at Curtin University has simulated 300 million years of tectonic plate movement to predict the formation of a supercontinent called Amasia. The modeling estimates the Pacific Ocean closing and America colliding with Asia.

The Kingdom of Denmark just got a teeny bit bigger after researchers from the University of Copenhagen accidentally discovered the world's northernmost island. Measuring only 100 x 200 ft, the still unnamed isle is located off the coast of Greenland.
