Traces Of Carbon In Mars Meteorite Stir Debate About Life On Red Planet

An international team of researchers say they’ve found evidence of biological activity inside a meteorite that fell to Earth from Mars three years ago–in other words, possible evidence that there was once life on the red planet.

But other scientists aren’t convinced.

The meteorite in question is the “Tissint” specimen, which famously fell on the Moroccan desert on July 18, 2011.

As the team of researchers–including scientists in China, Japan, Germany, and Switzerland–report in a new paper, chemical, microscopic, and isotope analyses show traces of organic carbon within tiny fissures in the space rock, and that the carbon had to have been deposited before the rock left Mars. Just check out the video above describing the research.

“I’m completely open to the possibility that other studies might contradict our findings,” Dr. Philippe Gillet, director of the EPFL Earth and Planetary Sciences Laboratory in Lausanne, Switzerland and a co-author of the paper, said in a written statement. “However, our conclusions are such that they will rekindle the debate as to the possible existence of biological activity on Mars–at least in the past.”

And contradiction wasn’t long in coming.
