Asteroid Found with Rings! First-of-Its-Kind Discovery Stuns Astronomers Video, ImagesBy Nola Taylor Redd, Space.com Contributor   |   March 26, 2014 02:02pm ET4 0 3Submit0Reddit Scientists have made a stunning discovery in the outer realm of the solar system — an asteroid with its own set of rings that orbits the sun between Saturn and Uranus. The space rock is the first non-planetary object ever found to have its own ring system, researchers say.The pair of space rock rings encircle the asteroid Chariklo. They were most likely formed after a collision scattered debris around the asteroid, according to a new study unveiled today March 27. The asteroid rings also suggests the presence of a still-undiscovered moon around Chariklo that’s keeping them stable, researchers said.”We weren’t looking for a ring and didn’t think small bodies like Chariklo had them at all, so the discovery — and the amazing amount of detail we saw in the system — came as a complete surprise!” study leader Felipe Braga-Ribas, of the National Observatory in Brazil said in a statement today.

Landslide and Barrier Lake Near Oso, Washington

NASA image of the day No Comments

On March 22, 2014, a rainfall-triggered landslide near Oso, Washington sent muddy debris spilling across the North Fork of the Stillaguamish River. The slide left an earthen dam that blocked the river, causing a barrier lake to form. The Operational Land Imager (OLI) on the Landsat 8 satellite acquired this image of landslide debris and the barrier lake on March 23, 2014.
