A Planet that might have aliens on it was recently found. It is so close enough that we could travel there.
The new world is just slightly bigger than Earth and sits about four light years away, orbiting Proxima Centauri. That star is the nearest one to our solar system.
As such, it is the most easily organized and understood of any “second Earth” that has ever been found. And it appears to be almost utterly set up to serve as a home for alien life.
“We hope these findings inspire future generations to keep looking beyond the stars. The search for life on Proxima b comes next.”
Proxima b is far closer to its star than we are, taking just 11.2 days to complete one orbit and sitting only 5% as far away from its star as we do from ours. But because that star is much dimmer, it is still within the habitable zone where there could be water on the planet and, as a consequence, life.
But there are other issues with Proxima b as a potential home for nearby aliens. The star pelts its planet with powerful sunlight rays and X-rays, which would mean that anything living there would find it much harder and so would have to become hardened against that radiation.
