Alien Life Could Thrive On Four Earth-Like Planets Close To The Solar System, Says Study
Alien life could be evolving right now on some of the nearest exoplanets to our solar system, claim scientists at Cornell University in Ithaca, New York. Their proof is you.
It's been presumed that the high levels of radiation known to be bombarding many of the rocky Earth-like exoplanets discovered so far by astronomers precludes life, but that theory is turned on its head by new research published [open, DOI: 10.1093/mnras/stz724] [DX] in Monthly Notices of the Royal Astronomical Society.
In "Lessons from Early Earth: UV Surface Radiation Should Not Limit the Habitability of Active M Star System", the authors say that all of life on Earth today evolved from creatures that thrived during an era of much higher levels of UV radiation assault. So why not life on alien worlds? It also poses another question: does the evolution of life actually require high levels of radiation?
The exoplanets studied are Proxima b, TRAPPIST-1e, Ross 128 b, and LHS 1140 b.

That's so true. And in Japan they're letting folks go back to their homes in one of the Fukushima towns. After they found out it's very safe there now. foxnews.com/world/residents-from-parts-of-fukushima-plant-hometown-allowed-to-return-after-japan-lifts-evacuation [foxnews.com]
