Alien life signs on Mars may be sought out in future explorations, as recent geological analysis has revealed where to start the search. While the red planet is a dusty, frigid wasteland today, evidence suggests that it used to be a wet, warm planet.
The study of alien life, led by the NASA and SETI Institute researchers, found evidence for carbonate rocks in the Huygens basin on Mars, which is a 280-mile region of low-lying terrain with impact craters. The rocks that are estimated to be 3.8 billion years of age provide a strong evidence of a marine domain with Earth-like chemistry. Even the evidence discovered in the atmosphere indicates that a vast portion of Mars' surface used to be covered by an ocean. But in order to determine if the red planet's ancient habitats were indeed Earth-like, the researchers need to find out the specific types of minerals that were present, according to Trusted Reviews.
