+ - 'Saturn on Steroids' Exoplanet Discovered?->

Submitted by

astroengine writes "By analyzing the silhouette of an exoplanet passing in front of its parent star 420 light-years away, astronomers have discovered what may be a large gas giant world sporting a ring system. Could it be Saturn's twin? Possibly.

"When I first saw the light curve, I knew we had found a very weird and unique object," said University of Rochester astronomer Eric Mamajek. "After we ruled out the eclipse being due to a spherical star or a circumstellar disk passing in front of the star, I realized that the only plausible explanation was some sort of dust ring system orbiting a smaller companion — basically a 'Saturn on steroids.'""
