Scientists exploring Mars and analysing Martian meteorite samples have found organic compounds essential for life: nitrogen-bearing organics in a 4-billion-year-old Martian meteorite. With a new high-spatial resolution in-situ N-chemical speciation technique, they found organic materials — either synthesized locally or delivered during the Noachian — preserved intact in carbonate minerals over a long geological period. Their presence requires abiotic or biotic N-fixation and ammonia storage, suggesting early Mars had a less oxidizing environment than today.

Could Invisible Extraterrestrial Life Forms Really Exist Among Us?0

Life is pretty easy to recognize. It moves, it grows, it eats, it excretes, it reproduces. Simple. In biology, researchers often use the acronym ‘MRS-GREN’ to describe it. It stands for movement, respiration, sensitivity, growth, reproduction, excretion and nutrition. But Helen Sharman, Britain’s first astronaut and a chemist at Imperial College London, recently said that alien life forms that are impossible to spot may be living among us. How could that be possible?
