Fossilised Bacteria in Meteorite From Mars is Proof of Life, Study Claims


A second Martian meteorite which shows 'signs of microbial life' has been found, Hungarian researchers say in their report on the latest study, published in Open Astronomy, reigniting 'bacterial' fossils claims made 20 years ago by NASA.

The meteorite, officially known as ALH-77005, is claimed to contain 'biosignatures', which researchers describe as textures and features left behind by organisms.

Experts resorted to advanced imaging techniques that they say revealed microfilaments created by fossilised Martian microbes.

A team of researchers from the Hungarian Academy of Science (HAS) Research Centre for Astronomy and Earth Sciences used optical microscopy and infrared technology to study the textures and features of the thin sample of ALH-77005.

The Hungarian researchers also examined minerals and other material embedded in the stone, and conducted isotope tests to check for the chemical components essential for life. The studies led them to conclude that the microscopic filaments inside could point to the presence of bacteria which survive by eating iron rust.

Evidence shows that Venus, Mars, and Earth all crossed the orbits of each other in the distant past. So, if there is evidence of past life on Mars, we can't be sure that it didn't come from Earth -
