Are there more galexy where life is present.

Dear student,
Earth is the only planet where free atmospheric oxygen is found and the oxygen is present bound with other chemicals. The supply of oxygen in the atmosphere comes mostly from plants. As other planets do not have any life form, it is difficult to obtain oxygen there.
GLIESE 581C is a new planet discovered outside our solar system. This is recognized as Super Earth which is 5.6 times bigger than earth. Super earth is reported to be earth-like as it is situated within the habitat zone of its star as our earth’s position from the sun. It is assumed that water may be available there and the distance from its stars is moderate. Hence, living things may grow one day if all the aspects of living conditions are found.
