Chemicals once found in hairspray may serve as signs of alien life on faraway worlds, researchers say. These compounds may reveal that extraterrestrials have disastrously altered their planets.

Small 'nanoflares' erupting from the sun might be the key to unlocking a cosmic mystery, according to a new study.
13 August 2014, 08:01 AM ET
A special U.N. action team has recommended the creation of an international warning network, which would gather and analyze asteroid data and provide timely warnings to national authorities if a potentially hazardous space rock were to threaten Earth.

Cassini looked on last month as methane clouds floated above Ligeia Mare, a big hydrocarbon sea near Titan's north pole. Few clouds had been seen on Titan since 2010, so researchers are trying to gauge the significance of the new observations.
12 August 2014, 04:11 PM ET
The international Cassini-Huygens mission scanned a gathering cloud mass over the methane sea known as Ligeia Mare on Saturn’s largest moon Titan between July 20th and 22nd 2014. Full Story: http://goo.gl/gIb2r9
