The surprisingly large size of these extraterrestrial gemstones is the first direct evidence for the mysterious planet that has since disappeared from our solar system
Specks of diamond inside a meteor that fell from space into the Nubian Desert of northern Sudan were formed inside a long-lost planet in the early years of the solar system, according to a new scientific report.
The surprisingly large size of these extraterrestrial gemstones is the first compelling and direct evidence for the mysterious planet that has since disappeared from the solar system, either by colliding and being absorbed into another planet, or being incinerated in the sun, or cast off into outer space.
At least some of it stuck around, however, in the form of a small asteroid, perhaps four metres across, that spent millions of years in some kind of local orbit until one special night in 2008, when astronomer Richard Kowalski noticed a blip on a screen at the Mount Lemmon telescope in Arizona.
