#Alien #Bizzare – ‘Super aliens’ could feed on cosmic rays: Bizarre forms of life might thrive on radiation that would kill humans : When it comes to our exploration of the solar system, one of the most dangerous aspects of space for the human body is cosmic radiation. But for a totally different kind of living thing, cosmic radiation could actually be a source of life.
This is according to a new study, which suggests life on other planets might survive on the energy provided by cosmic radiation.
The findings open up the possibility of finding alien life forms on planets we previously thought were uninhabitable.
Astrobiologist Dr Dimitra Atri, from the Blue Marble Space Institute of Science in Seattle, was inspired by an organism found on Earth. The rod-shaped bacterium called Desulforudis audaxviator lives 1.8 miles (2.8km) underground, where there is no light, carbon or oxygen.
This strange bug gets its energy from the radioactive uranium found in the mine. ‘It really grabbed my attention because it’s completely powered by radioactive substances,’ Dr Atri told Science.
‘Who’s to say life on other worlds doesn’t do the same thing?’. The Earth is constantly bombarded by high energy particles like protons, electrons and atomic nuclei.
These particles make up the so-called ‘cosmic radiation’, and they originate from huge explosions in dying stars, called supernovae. But our planet’s magnetic field and thick atmosphere prevent these dangerous particles from entering and affecting life on the planet.
Many other planets do not have the same kind of protection, and these kind of worlds have previously been ruled out in the search for alien life. However, the new findings, published in the Journal of the Royal Society Interface, could change what kind of planets we search on. Source: dailymail
