From the Ted Talk by Joel Levine: Why we need to go back to Mars

Unscramble the Blue Letters


The most itrgninuig and puzzling measurement, in my opinion, we've obtained of Mars, was released eearilr this year in the magazine Science. And what we're looking at is the presence of the gas mnhteae, CH4, in the atmosphere of Mars. And you can see there are three distinct regions of methane. Why is methane important? Because on Earth, almost all -- 99.9 percent -- of the methane is prouecdd by living systems, not little green men, but microscopic life below the surface or at the surface. We now have evidence that methane is in the atmosphere of Mars, a gas that, on Earth, is biogenic in orgiin, produced by liinvg systems. These are the three plumes: A, B1, B2.

Original Text


The most intriguing and puzzling measurement, in my opinion, we've obtained of Mars, was released earlier this year in the magazine Science. And what we're looking at is the presence of the gas methane, CH4, in the atmosphere of Mars. And you can see there are three distinct regions of methane. Why is methane important? Because on Earth, almost all -- 99.9 percent -- of the methane is produced by living systems, not little green men, but microscopic life below the surface or at the surface. We now have evidence that methane is in the atmosphere of Mars, a gas that, on Earth, is biogenic in origin, produced by living systems. These are the three plumes: A, B1, B2.
