Aliens Could be Hiding Underground on Mars, Scientists Reveal
Due to the sheer distance between Earth and Mars (about 33.9million miles), it's not easy to explore our space neighbour. That's why Nasa uses satellites, probes, telescopes, rovers and landers to investigate the surface of Mars. No evidence of life has been found yet, so now scientists are pinning their hopes on below-surface digging – a far more difficult task.
Michalski thinks that humans are biased by our own existence on Earth to think life must be lurking on a planet's surface. But it might not be the case. When Mars was a young planet, its surface would've been quite similar to Earth. However, Mars eventually lost its magnetic field, exposing it to intense radiation that would've made on-surface living difficult. Life may have already been "cooking" on Mars before that happened – and simply adapted to life underground. "Life could have emerged in those hydrothermal settings and survived in the subsurface for quite a long time," said Michalski.
