The Astronautical Society of India (ASI) in association with Indian Space Research Organization (ISRO) organized a planetary science workshop on Dec 27 and 28, here.
Astro-biologist, cosmologist, theoretical physicist and author Prof Paul Davies of Arizona State University, was present to deliver lectures on Mars Exploration and Origin of Life.
Davies, whose most recent book is ´The Erie Silence: Are we alone in the Universe´, touched upon the improved experiments to detect living micro-organisms in deeper Martian surfaces, as well as issues of defining life in an extra-terrestrial context.
In his lecture on ´Origin of life´, he presented the possibilities of life on earth in the form of micro-organisms as early as 3.6 billion years and/or transfer of these living cells through meteorite of the nearby Mars planet.
He also postulated the possibility of different form of living cells with totally different genetic codes, thereby creating a so-called 'Shadow biosphere´.
