A gem stone found Earth has indicated the evidence of life on Mars, unbelievable it may be, but scientists have discovered the gem stone called opal may serve as evidence to possible life on the Red Planet.
The gem stone, scientists believe had fallen on Earth when a meteorite hit the Martian surface and carved out a huge stone along with it to reach the surface of our earth in 1911, after travelling for millions of years. The stone weighing 1.7 gram was preserved at the Natual History Museum and named Nakhla, after an Egyptian town.
The researchers at the University of Glasgow insist that the size of the stone was small but they have found opal in it, which are found on earth near hot water springs where microbial life grows. Prof. Martin Lee, lead author, said the opal can trap these microbes and preserve them for millions of years.
Lee says it definitively confirms findings from NASA’s imaging and exploration of the Martian surface which appeared to show deposits of opal and secondly, opals on earth found in hot springs trap microbial life and preserve them for millions of years. “If Martian microbes existed, it’s possible they too may be preserved in opal deposits on the surface of Mars,” Lee said.
As evidence of water and opals on Mars surface was already discovered, researchers believe that future rovers can unfold the evidence of microbial life on the Red Planet for sure. The chances are high that water must have flown and trapped microbes in these opals, a clear proof of alien life on Mars.
“Closer study of Martian opals by future missions to Mars could well help us learn more about the planet’s past and whether it once held life,” said Martin Lee of the University of Glasgow’s School of Geographical and Earth Sciences.
Opal, a form of silica found in Australia, can take any color with variable optical density from transparent to opaque, said the research paper published in the journal Meteoritics and Planetary Science.
