New Mexico Tech's Magdalena Ridge Observatory (MRO) is already making its mark in the annals of MROastronomy research after being recently tasked by NASA to make detailed observations of an asteroid that is now given a 1 in 75 chance of hitting Mars on January 30, 2008. ...> Full Article

New research reveals a large asteroid breakup to be the likely source of the impactor that caused a mass extinction event on Earth 65 million years ago (9/6/2007)

The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 65 million years ago has been traced back to a breakup event in the main asteroid belt. A joint U.S.-Czech team from Southwest Research Institute (SwRI) and Charles University in Prague suggests that the parent object of asteroid (298) Baptistina disrupted when it was hit by another large asteroid, creating numerous large fragments that would later create the Chicxulub crater on the Yucatan Peninsula as well as the prominent Tycho crater found on the Moon. ...> Full Article
