Forget Paris Hilton, Brittany's panties, and the Hooter Girl who couldn't fly despite her bounce--this news is hot, sexy, and solves an ancient mystery.
The Michigan Crater has long been the focus of scientific research and speculation. A "Himalaya-sized object", about 12 miles across, whacked into Earth millions of years ago.
The second-largest impact--the largest crater is in South Africa--led to a scientific mystery: how'd that big hole get there? Now researchers are convinced they know what happened millions of years ago: a science fiction scenario that actually happened.
Eighteen hundred million years ago, an area that now spans the U.S.-Canadian border near Lake Huron was battered by a rain of molten debris and mega-tsunamis caused by what is thought to be the second largest impact in Earth's history. But the source of that collision has long been a mystery.Now, telltale signs of what's called the Sudbury impact of southern Ontario — including shocked quartz, once-molten rock spherules and extraterrestrial iridium — are ruling out a comet and making a strong argument that it was an asteroid that struck southern Canada all those eons ago.
"It was a Himalaya-sized object that slammed into the Earth," said geologist Peir Pufahl of Acadia University in Nova Scotia.
