・Mars rocks 'may contain evidence of life'
Jul 31, 2010
Scientists have identified rocks which they claim could contain evidence of life on Mars.An international team, led by the Search for Extraterrestrial Intelligence Institute (SETI) in California, has made the discovery in the ancient rocks of Nili Fossae, the 'Earth and Planetary Science Letters' reported.
Their work has revealed that the ancient rocks of Nili Fossaeare are almost identical to those in the Pilbara region of north-west Australia where some of the earliest evidence of life on Earth was recorded and preserved in mineral form.
In fact, the scientists claim the same "hydrothermal" processes that preserved these markers of life on Earth could have taken place on the Red Planet at Nili Fossae.
The study found that the ancient rocks shared similar minerals and features, known as "stromatolites". It is significant because Pilbara is used to study the early stages of life on Earth 3.5 billion years ago.
