Microbes Take their Sulfur Light

A model explaining the preferences of deep-sea microbes can help reveal the ancient past – as well as predict the future

A satellite image of Olympus Mons, Mars, the largest volcano in the solar system at about three times the height of Mount Everest. Around 3.5 to 4.0 billion years ago, the release of volcanic gases, especially the greenhouse gas sulfur-dioxide, may have warmed the surface of Mars episodically, thereby explaining the presence of geomorphological features indicative of the flow of water on the planet's ancient surface

A new model suggests volcanic activity in Mars’ distant past spewed enough greenhouse gases to warm the atmosphere and melt the ice
