A meteorite from Mars showed signs of life in fossilized bacteria, scientists claimed.
Experts using advanced imaging techniques say they found microfilaments created by fossilized Martian microbes in meteorite, officially known in the ALH-77005. The study, published in Open Astronomy, came from Dr. Ildiko Gyollai from the Hungarian Academy of Science (HAS) Research Center for Astronomy and Earth Sciences.
His team uses optical microscopy and infrared technology to study the textures and features the thin sample of ALH-77005.
The textures and features left by the organisms are called "biosignatures."
Researchers also studied mineral and other rock material and conducted the isotope test to find out if any compounds needed for the life of any chemical.
They concluded that microscopic filaments could be evidence of bacteria that survived by eating iron dust.
The study authors say on paper: "Comparing recent results and interpretation to other meteorites, it can be raised, that in these similarities microbially mediated biosignatures may be proposed germs by [iron oxidizing bacteria] on Mars. "
At that time, US President Bill Clinton backed up scientists to continue their research saying it could offer the "most breathtaking perspective" in the universe.
He said: "Now the rock 84001 speaks to us all billions of years and millions of miles."
"It speaks of the probability of life. If this discovery is confirmed, it will certainly be one of the most spectacular views in our universe that science has been discovered. "
" Its implications are as big and astonishing as you can imagine. Even though it promises answers to some of our oldest questions, it still implies something more important. "
However, it was claimed that it would be impossible to prove if" biosignatures "were not made by non-biological processes.  The stone part of the recent study was discovered in Antarctica during the Japanese National Institution of Polar Research in the 1977-1978 mission.
