We are not alone? New NASA research suggests possibility of life on Mars

Photosynthesis is fundamentally a process that lets plants, algae, and immoderate bacteria person sunlight into c dioxide, and h2o into oxygen and glucose. Photosynthesis is liable for generating overmuch of Earth’s atmospheric oxygen. The probe proposes that an adequately heavy furniture of ics connected Mars whitethorn enactment arsenic a shield against the Sun’s hash radiation astatine the aforesaid clip allowing capable airy for photosynthesis starring to the instauration of ‘radiative habitable zones’.

The paper’s pb author, Aditya Khuller of Nasa’s Jet Propulsion Laboratory, said that if we are to find beingness anyplace successful the beingness today, the Martian crystal exposures are astir apt 1 of the astir accessible places. 

The probe does not explicitly authorities that beingness exists oregon ever existed connected the planet. However, the survey offers immoderate caller insights into imaginable areas to explore. “We are not stating we person recovered beingness connected Mars, but alternatively we judge that dusty Martian crystal exposures successful the mid-latitudes correspond the astir easy accessible places to hunt for Martian beingness today,” Khuller was quoted arsenic saying by Space.com.

Earth and Mars beryllium successful the ‘habitable zone’ of the Sun with temperatures that let for h2o to exist. Earth has oceans covering implicit 70 per cent of its surface, however, Mars remains dry. Nasa’s Mars missions person earlier shown impervious of past liquid h2o connected the reddish planet. These were gauged from the adust water beds, and beingness of h2o crystal successful unexplored areas. 

According to scientists, Mars mislaid its liquid h2o billions of years agone aft its magnetic tract collapsed exposing it to harsh ultraviolet radiation. Mars has the beingness of 30 per cent much harmful ultraviolet rays, arsenic it does not person a protective shield similar Earth’s ozone layer. 

Computer simulations, arsenic portion of the study, showed that the dusty crystal connected Mars whitethorn melt internally with overlying crystal preventing subsurface liquid h2o from vapourising. Khuller noted that sunlight and liquid water, 2 cardinal ingredients for photosynthesis, could beryllium conscionable beneath the ice.
