A planet 1,200 light-years away is a good prospect for a habitable world
A distant planet known as Kepler-62f could be habitable, a team of astronomers reports. View News Article (2016-05-27)

Ancient tsunami evidence on Mars reveals life potential
The geologic shape of what were once shorelines through Mars' northern plains convinces scientists that two large meteorites - hitting the planet millions of years apart - triggered a pair of mega-tsunamis.  View News Article (2016-05-20)

MIT scientists compile list of potential gases to guide search for life on exoplanets
A new approach intended to maximize the chances of identifying planets orbiting nearby stars that support life focuses on creating a comprehensive list of the molecules that might be present in the atmospheres of these exoplanets. View News Article (2016-05-09)

Portion of ancient Australian chert microstructures definitively pseudo-fossils
A team of scientists including Carnegie's Dina Bower and Andrew Steele weigh in on whether microstructures found in 3.46 billion-year-old samples of a silica-rich rock called chert found in Western Australia are the planet's oldest fossils.  View News Article (2016-02-17)

New study challenges Jupiter's role as planetary shield, protecting Earth from comet impacts
Not only is the "Jupiter as shield" concept, implying that the planet shields Earth from comet impacts, not true, but perhaps Jupiter's most important role in fostering the development of life on Earth was just the opposite -- delivering the volatile materials from the outer Solar System needed for life to form.  View News Article (2016-02-04)

Newfound Earth-size exoplanet may be an important milestone in search for alien life
Researchers have discovered an exoplanet just slightly bigger than Earth and located much closer to our Solar System than any other terrestrial, alien world. Called GJ 1132b, it orbits a tiny red, dwarf star just 39 light-years away.  View News Article (2015-11-12)

Earth-like planets around small stars likely have magnetic fields, aiding chance for life
Earth-like planets orbiting close to small stars probably have magnetic fields that protect them from stellar radiation and help maintain surface conditions that could be conducive to life, according to research from astronomers at the University of Washington. View News Article (2015-09-29)

Oxygen is not definitive evidence of life on habitable extrasolar planets
The Earth's atmosphere contains oxygen because plants continuously produce it through photosynthesis. This abundant supply of oxygen allows life forms like animals to flourish.  View News Article (2015-09-10)

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)
