Signals beamed from the Arecibo Observatory in Puerto Rico penetrated deep into the moon. They then bounced back and were detected by the Green Bank Telescope in West Virginia, at 330 feet (100 m) wide, the planet's biggest fully steerable radio telescope...

The incredible anticyclonic storm on the gas giant is the smallest it has ever been in visually recorded history. Imagery from the space telescope from 1995, 2009, and 2014 show its decline. Full Story: http://goo.gl/5aAEdD...

New images from Rosetta show that an 800-mile-long cloud of dust, known as a coma, has sprouted from the core of the comet 67P/Churyumov-Gerasimenko. Rosetta's captured this coma in a series of photos taken between March 27 and May 4....
