Alien life on Super-Earth can survive longer than we Earthlings due to long-lasting protection from cosmic rays
Laser experiments show their magnetic fields shielding their surfaces from radiation last longer
Life on Super-Earths may have more time to develop and evolve, thanks to their long-lasting magnetic fields protecting them against harmful cosmic rays, according to new research published in Science.
Space is a hazardous environment. Streams of charged particles traveling at the speed of light, ejected from stars and distant galaxies, bombard planets. The intense radiation can strip atmospheres and cause oceans on planetary surfaces to dry up over time, leaving them arid and incapable of supporting habitable life. Cosmic rays, however, are deflected away from Earth, however, since it’s shielded by its magnetic field.
Now, a team of researchers led by the Lawrence Livermore National Laboratory (LLNL) believe ...
