Brown University researchers have found compelling evidence of thick, recurring glaciers on Mars, a discovery that suggests that the Red Planet's climate was much more dynamic than previously believed "“ and could change again. Results are published on the cover of Geology magazine.The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. About 3.5 billion years ago, the Red Planet had extensive flowing water and then fell quiet -...

COLUMBUS, Ohio -- Scientists have gathered more evidence that suggests flowing water on Mars -- by comparing images of the red planet to an otherworldly landscape on Earth. In recent years, scientists have examined images of several sites on Mars where water appears to have flowed to the surface and left behind a trail of sediment. Those sites closely resemble places where water flows today in the McMurdo Dry Valleys in Antarctica, the new study has found. The new study bolsters the notion...

PASADENA, Calif. -- NASA's Mars Reconnaissance Orbiter is examining several features on Mars that address the role of water at different times in Martian history. Features examined with the orbiter's advanced instruments include material deposited in two gullies within the past eight years, polar ice layers formed in the recent geologic past, and signs of water released by large impacts when Mars was older. Last year, discovery of the fresh gully deposits from before-and-after images taken...

By RANDOLPH E. SCHMID WASHINGTON - An orbiting spacecraft has sent back new evidence for the presence of water on Mars. Scientists have long debated whether water flowed on the red planet, with evidence increasing in recent years. The presence of water would raise the possibility of at least primitive life forms existing there. Images from a camera aboard NASA's Mars Reconnaissance Orbiter show alternating layers of dark- and light-toned rock in a giant rift valley. Within those...

By ALICIA CHANG Associated Press writer LOS ANGELES -- For decades, scientists have scoured Mars in search of water, a basic ingredient for primitive life. But the best clues were always tied to the ancient past when the Red Planet was warmer and wetter. On Wednesday, scientists made the startling announcement that water may still course through the frigid surface. Crisp photographs taken by NASA's old Mars Global Surveyor before it lost contact with Earth last month do not...

By ALICIA CHANG Associated Press Video: Possible Water Found on Mars LOS ANGELES -- New photographs from space suggest that water occasionally flows on the frigid surface of Mars, raising the tantalizing possibility that it is hospitable to life, scientists reported Wednesday. The new images, taken by NASA's Mars Global Surveyor before it lost contact with Earth, do not actually show flowing water. Rather, they show changes in craters that provide the strongest evidence yet that...

By JOHN JOHNSON JR. NASA scientists announced Wednesday that they had found evidence that water still flows over the surface of Mars - sporadic gushers that increase the possibility that the Red Planet could harbor some form of life. Using images obtained by the Mars Global Surveyor spacecraft, the researchers concluded that geologic changes in the shapes and sizes of gullies cut into the walls of two Martian craters were likely made by flowing water. The team looked at two sets of...

By Warren E. Leary Pictures of Martian gullies taken several years apart strongly suggest that water still flows at least occasionally on the surface of the planet, scientists have announced. While water ice and water vapor have long been known to exist below the surface of Mars in the relatively recent past, and water ice has been seen at the poles, this is "the strongest evidence to date that water still flows occasionally on the surface of Mars," Michael Meyer, the lead scientist for...

NASA sees hint of liquid water on Mars WASHINGTON, Dec. 6 (Xinhua) -- Images sent back by NASA's Mars Global Surveyor orbiter suggest the existence of liquid water on Mars which heightens the potential for microbial life on the Red Planet, NASA scientists said on Wednesday. NASA scientists made the judgement based on images taken in 2004 and 2005 revealing bright new deposits seen in two gullies on Mars that suggest water carried sediment through them sometime during the past seven...
