NASA found proof of alien life nine years ago – and these photos from an old Mars rover are the proof.
Hot spring silica deposits were photographed on the red planet in 2007 by NASA’s Spirit Rover.
Now geologists have found similar deposits here on earth and made a startling discovery.
Such structures are made with the help of tiny organisms – and could be also on Mars.
The team from Arizona State University found the deposits in El Tatio, a rugged part of the Andes in Chile.
It’s a Mars-like environment, with freezing temperatures at night, plenty of UV light from the sun, and thin, dry air.
Researchers Steve Ruff and Jack Farmer wrote in the science journal, Nature, that El Tatio is among the places most like Mars on Earth.
“Such conditions provide a better environmental analog for Mars than well-known geothermal sites on Earth,” they wrote.
