Ancient Asteroid Generated the Hottest Temp Ever Recorded on Earth

Sep 15
When an asteroid smashes into the Earth things get pretty toasty. A 17 mile-wide crater in Canada was home to what scientists say is the hottest temperature ever recorded in Earth’s crustal rock, a whopping 4,300 degrees Fahrenheit. They didn’t just stick a thermometer in there, of course, the crater is some 36 million years old. Instead, researchers from Curtin University in Australia looked to the rocks. Embedded in the crater walls were crystals of

Asteroid Apophis has one in 100,000 chance of hitting Earth

Aug 17
by Tomasz Nowakowski, Astrowatch.net The huge, nearly 400-meter-wide asteroid Apophis is still on a list of hazardous near-Earth objects (NEOs), regarded as a potential threat to the planet. However, new calculations made by NASA's Jet Propulsion Laboratory (JPL) show that Apophis' odds of Earth impact are lower than previously estimated. "We cannot yet exclude the possibility that it could impact our planet, but we can calculate that the chance of Earth impact is only one-in-100,000

Astronomers identify oldest known asteroid family

Aug 09
Southwest Research Institute (SwRI) was part of an international team that recently discovered a relatively unpopulated region of the main asteroid belt, where the few asteroids present are likely pristine relics from early in solar system history. The team used a new search technique that also identified the oldest known asteroid family, which extends throughout the inner region of the main asteroid belt. The main belt contains vast numbers of irregularly shaped asteroids, also known
