What does the Home Plate plateau on the planet Mars have in common with El Tatio hot springs in Chile?
Finger-like structures. What’s significant about that? If the structures were formed in the same way, it suggests that Mars wasn’t always the inhabitable planet that it is.
Back in 2007 when the NASA rover named Spirit was still functioning and roaming on the surface of Mars, it was able to gather white materials which turned out to be made mostly of what we know as silica, a tough glass-like substance. More interestingly, it was also able to capture images of finger-like rock formations on the Home Plate plateau — a region on Mars that scientists believe may have been home to numerous geysers, much like Earth’s Yellowstone National Park.
