Antarctica Yields Fossils of a Destroyed Dwarf Planet
Rocks can be many things: they were probably our earliest weapons, they've been ballast on our journeys of exploration, even modern-art pieces. But a pair recovered from Antarctica may be the grandest application yet - tombstones for an entire world. Lunar and Planetary Institute researcher Allain Treiman believes that them to be pieces of a destroyed dwarf planet, relics from the creation of the solar system. Full story:
* Primitive asteroids in the main asteroid belt may have formed far from the sun... "Our model shows that comets are relatively easy to break up when hit by something, at least when compared to typical asteroids. It is unavoidable that some of the debris went on to land on asteroids, the Moon and the Earth. In fact, some of the leftovers may still be arriving today," says Dr. Alessandro Morbidelli of the Observatoire de la Cote d'Azur in Nice, France.
