Scientists have long known that the Earth rings like a giant bell after large earthquakes - albeit a bell that no one could ever hear - due to slight deformations that leave the planet jiggling like a bowl of Jell-O.

Data sent back by the Huygens space  probe from the Saturnian moon Titan show a frozen, orange world  shrouded in a methane-rich haze with dark ice rocks dotting a  riverbed-like surface the consistency of wet sand, scientists  said on Saturday.

European Space Agency -- ESAÃ¢ÂÂs quartet of space-weather watchers, Cluster, has discovered vortices of ejected solar material high above the Earth.     The superheated gases trapped in these structures are probably tunnelling their way into the EarthÃ¢ÂÂs magnetic Ã¢ÂÂbubbleÃ¢ÂÂ, the magnetosphere...

Einstein was right -- again.  Satellites that have been pulled slightly off their orbits show  that the Earth is indeed twisting the fabric of space-time as  it rotates, scientists said on Thursday.
