Extremophiles Thrive on Earth’s Scientific Stand-in for Mars

The unimaginably arid conditions of South America’s Atacama Desert have mad it the perfect scientific stand-in for Mars. So in a place that is quite literally almost alien, it makes sense we’d find microbes as strange as these.

Specifically, researchers have found microbes inside some of the region’s volcanoes, which are incredibly dry even by the already ludicrous standards of the Atacama. Fungi and bacteria have been found in the recently collected soil samples, but of greatest interest are the least complex of the organisms, the archaea. Those found in the Atacama volcanoes seem to have evolved a way of converting energy – one of the most basic processes an organism undertakes – in a way unlike any other known species.

Geologic Map of Io, the mysterious Jovian moon and the most volcanically active object in the solar system

Pulling together decades of data from the Voyager, Galileo, Cassini, and New Horizon probes, as well as the Hubble Space Telescope, scientists at the US Geological Survey have put together a complete geological map of Io, the beautiful, mysterious Jovian moon. Io is the most volcanically active object in the solar system, and its surface reflects that: unlike everything else around, it has no craters, a sign that its surface is constantly being remade. That’s thanks to volcanoes that shoot out more than 100 times more lava per year than Earth’s.
