Yes, Water Actually Found on Mars!

Yes, Water Actually Found on Mars!

  The first scoop of soil analyzed by the analytical suite in the belly of NASA’s Curiosity rover reveals that fine materials on the surface of the planet contain several percent water by weight. The results were published today in Science as one article in a five-paper special section on the Curiosity mission.   The Sample Analysis at Mars [continue reading]

No Methane on Mars Does Not Mean Life Never Arose There

No Methane on Mars Does Not Mean Life Never Arose There

  Data from NASA’s Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data reported by U.S. and international scientists indicated positive detections.

Could Panspermia be Possible?

Could Panspermia be Possible?

  It sounds like science fiction, but the theory of panspermia, in which life can naturally transfer between planets, is considered a serious hypothesis by planetary scientists. The suggestion that life did not originate on Earth but came from elsewhere in the Universe (for instance, Mars), is one possible variant of panspermia. Planets and moons [continue reading]

Titan has a Thick, Rigid and Weathered Ice Shell

Titan has a Thick, Rigid and Weathered Ice Shell

  An analysis of gravity and topography data from Saturn’s largest moon, Titan, has revealed unexpected features of the moon’s outer ice shell. The best explanation for the findings, the authors said, is that Titan’s ice shell is rigid and that relatively small topographic features on the surface are associated with large roots extending into [continue reading]

Are We All Martians?

Are We All Martians?

  New research supports theory that life started on Mars   New evidence has emerged which supports the long-debated theory that life on Earth may have started on Mars. Professor Steven Benner will tell geochemists gathering today (Thursday 29 Aug) at the annual Goldschmidt Conference that an oxidized mineral form of the element molybdenum, which may have [continue reading]

Water on Moon's Surface Hints at Water Below

Water on Moon’s Surface Hints at Water Below

  NASA-funded lunar research has yielded evidence of water locked in mineral grains on the surface of the Moon from an unknown source deep beneath the surface.
