Alien Life May Feed Off Of Galactic Cosmic Rays


#Alien #CosmicRaysAlien Life May Feed Off Of Galactic Cosmic Rays : Extreme microbes living in hostile locations on Earth may be munching on cosmic rays that zip through space, says a study of a peculiar bacterium thriving in a dark gold mine.

If there is an existence of life on other planets, say, Mars, it too may be feeding off of cosmic rays in order to survive, the new research suggests, as reported in Space.

“When you have radiation penetrating deep below the surface, where there might be water on Mars or [Jupiter’s moon] Europa, then it could start chemical reactions that life could use,” said study author Dimitra Atri, a research scientist at the Blue Marble Space Institute of Science in Seattle.

Explaining further, Atri said that organisms that munch on galactic cosmic rays could even survive on rogue planets which are not bound to any star and drift throughout interstellar space. Life on Earth relies primarily on light from the sun.

Photosynthesis takes place in the presence of sunlight, which, in turn, supplies the energy and nutrients that are used by other organisms in order to survive. Still, in the absence of light, organisms can use other sources of energy, such as chemical energy or heat energy, as suggested by previous studies.
