The Red Planet has a touch of green, according to atmospheric observations performed by the ExoMars Trace Gas Orbiter. It’s the first time this effect has been documented on a planet other than Earth.
It’s nothing to lose sleep over — really, I promise — but Earth’s atmosphere is leaking oxygen. Atmospheric oxygen levels have dropped by 0.7 per cent over the past 800,000 years, and while scientists aren’t sure why, they’re rather excited about it.
New findings from NASA’s Curiosity Rover provide evidence that significant amounts of oxygen once permeated the atmosphere of ancient Mars. The Red Planet, it would seem, was more Earth-like than we thought.
