Meteor in Wisconsin: Allen Hills meteorite 840001, from Mars and discovered in an expedition to Antarctica in 1984, became world famous twelve years later, when NASA and the White House announced jointly that the rock might contain traces of extraterrestrial life. The discovery sparked an intense debate that still stands today. A few months ago, a study published in the journal Geochimica et Cosmochimica Acta pointing back to this possibility and some websites specialized scientific information spread a rumor that the U.S. space agency would soon new data that confirm the presence of biological traces of microscopic creatures in the rock.
The truth is that, until now, scientists involved in research have adhered to the strictest silence. However, researchers at the University of Houston in Texas (USA) have released another new data on the meteor: it is much younger than previously thought. It has 4.091 million years, 400 less than initially estimated, as published in the journal Science. And what does this mean? For nothing less than the Allen Hills belongs to a time when Mars was wetter and had a magnetic field conditions are favorable for the simple life. A new data does not confirm anything, but it supports the possibility that some small beings stroll on the rock in their day and leave marks on their bodies.
