Researchers have identified rocks that they say could contain the
fossilised remains of life on early Mars. The team made their discovery
in the
ancient rocks of Nili Fossae.
Their work has revealed that this trench on Mars is a "dead ringer" for
a
region in Australia where some of the earliest evidence of life on Earth
has been buried and preserved in mineral form. They report the findings
in
the journal Earth and Planetary Science Letters.
The team, led by a scientist from the Search for Extraterrestrial
Intelligence Institute (Seti) in California, believes that the same
"hydrothermal"
processes that preserved these markers of life on Earth could have taken
place on Mars at Nili Fossae. The rocks there are up to four billion
years
old, which means they have been around for three-quarters of the history
of
Mars.
