Is a Colorado earthquake related to dinosaurs extinction impact?

Apr 12
by Seismological Society of America Researchers have found signs of fault displacement at well-known rock outcrops in Colorado that mark the end-Cretaceous asteroid impact that may have hurried the extinction of the dinosaurs. They will present their results in a poster at the 2017 Seismological Society of America’s (SSA) Annual Meeting. Norm Sleep of Stanford University and colleagues suggest that the impact, which occurred near the Yucatán Peninsula of Mexico, could have generated massive seismic

Encounters with Jupiter send asteroid on a bizarre backward spin

Mar 30
by John Timmer, from ArsTechnica.com Each time it approaches Jupiter, its orbit gets reset.   Jupiter is widely credited with providing Earth with a bit of protection. The immense gravity of the gas giant typically either sucks in asteroids and comets or flings them out into orbits where they pose our planet little danger. But astronomers have now identified an asteroid that’s in a stable orbital interaction with Jupiter. That interaction sends the asteroid around

Did an asteroid trigger ancient tsunamis on Mars?

Mar 27
by Weston Williams, from The Christian Science Monitor A team of researchers found that certain geological features on the Red Planet indicate that the impact that created the Lomonosov crater may have also created massive waves in an ancient Martian sea. A team of scientists believes that an asteroid impact at the site of Mars’ Lomonosov crater may have been responsible for the massive tsunamis thought to have swept the region three billion years ago. Scientists have
