Microscopic Signs of Life Shown to Survive on Mars

  An instrument similar to those used on Earth by art detectives and to sense explosives at airports will be taken into space for the first time by ExoMars, the European Space Agency’s mission to Mars in 2018. This Raman spectrometer will help space scientists to hunt for traces of Martian life. The European Space [continue reading]

Conditions on Mars Once Favorable for Life

  An analysis of a rock sample collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes.   Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon — some of the key chemical ingredients for life — in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed [continue reading]

More Indications Life Came To Earth From Outer Space

  Microorganisms that crashed to Earth embedded in the fragments of distant planets might have been the sprouts of life on this one, according to new research presented at the European Planetary Sciences Congress (EPSC) on 25 September.  The Sun is thought to have formed in a cluster of other stars around 4.5 billion years [continue reading]

"Arsenic Life" Needs Phosphorus After All

  Two new reports detailed online in the journal Science show that the bacterium known as GFAJ-1 requires small amounts of phosphate to grow — and that it cannot substitute arsenic for phosphorus to survive, as one previous report had suggested. The GFAJ-1 bacterium. Image credit: Science/AAAS The GFAJ-1 bacterium, found in the arsenic-rich sediments of California’s [continue reading]

Arctic Bacteria Help in the Search for Life on moon Europa

  In a fjord in Canada scientists have found a landscape similar to one of Jupiter’s icy moons: Europa. It consists of a frozen and sulfurous environment, where sulfur associated with Arctic bacteria offer clues for the upcoming missions in the search for traces of life on Europa.
