New plan proposed to send humans to Mars
A new, cost-constrained U.S. strategy to send humans on Mars, could be achieved within projected NASA budgets by minimizing new developments and relying mainly on already available or planned NASA assets.  View News Article (2015-06-30)


Nonphotosynthetic pigments could be biosignatures of life on other worlds
To find life in the universe, it helps to know what it might look like. If there are organisms on other planets that do not rely wholly on photosynthesis -- as some on Earth do not -- how might those worlds appear from light-years away? View News Article (2015-06-23)


Astronomers create array of Earth-like planet models
To sort out the biological intricacies of Earth-like planets, astronomers have developed computer models that examine how ultraviolet radiation from other planets' nearby suns may affect those worlds, according to new research published June 10 in Astrophysical Journal. View News Article (2015-06-18)


Atmospheric signs of volcanic activity could aid search for life
Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on.  View News Article (2015-06-09)


Geochemical process on Saturn's moon linked to life's origin
New work from a team including Carnegie's Christopher Glein has revealed the pH of water spewing from a geyser-like plume on Saturn's moon Enceladus.  View News Article (2015-05-07)


New research identifies diverse sources of methane in shallow Arctic lakes
New research into the changing ecology of thousands of shallow lakes on the North Slope of Alaska suggests that in scenarios of increasing global temperatures, methane-generating microbes, found in thawing lake sediments, may ramp up production of the potent greenhouse gas - which has a global warming potential 25 times greater than carbon dioxide. View News Article (2015-03-30)


Some potentially habitable planets began as gaseous, Neptune-like worlds
Two phenomena known to inhibit the potential habitability of planets -- tidal forces and vigorous stellar activity -- might instead help chances for life on certain planets orbiting low-mass stars, University of Washington astronomers have found.  View News Article (2015-01-29)


'Mirage Earth' exoplanets may have burned away chances for life
Planets orbiting close to low-mass stars - easily the most common stars in the universe - are prime targets in the search for extraterrestrial life. View News Article (2014-12-04)


Sustainability, astrobiology illuminate future of life in universe, civilization on Earth
Human-caused climate change, ocean acidification and species extinctions may eventually threaten the collapse of civilization, according to some scientists, while other people argue that for political or economic reasons we should allow industrial development to continue without restrictions. View News Article (2014-11-06)


Organic Molecules in Titan's Atmosphere Are Intriguingly Skewed
While studying the atmosphere on Saturn's moon Titan, scientists discovered intriguing zones of organic molecules unexpectedly shifted away from its north and south poles. These misaligned features seem to defy conventional thinking about Titan's windy atmosphere, which should quickly smear out such off-axis concentrations. View News Article (2014-10-23)
