Evidence suggests that billions of years ago, Mars may have been a thriving environment for life. Today, however, the planet is cold, dry ...
2 lut 2022 · Scientists want to know the duration of the habitable period; the longer it was, the more time there would have been for any potential Martian life to form. The new work extends the potentially habitable period on Mars by about 500 million years, into the late Hesperian age.

5 dni temu · But so far no evidence has been found that convinces even a sizable minority of the scientific community that the red planet was ever home to life. What the evidence does indicate, though, is that Mars was once a habitable world. Life, as we know it, could have taken hold there.
26 lip 2024 · Yesterday, NASA announced that a rock spotted on Mars by its Perseverance rover contained some of the best signs yet that ancient microbial life may have once existed on the Red Planet.
