Encounters with Jupiter send asteroid on a bizarre backward spin
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?
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
Blue fireball lights up sky over Sweden
A very large blue fireball illuminated the sky over Sweden around 20:30 UTC (21:30 CET) on March 20, 2017.
