A life might have existed once on the moon, claims the new research study. The atmosphere over the moon might have been far different from what it is there today, ready to support life, if only briefly.
Two senior planetary researchers found that the Moon might have had conditions to support simple life forms some four billion years ago. The same conditions might have arrived during a peak of volcanic activity 3.5 billion years ago, claim the researchers.
It is also claimed that the Moon, at that time, was spewing out a large amount of hot gases including water vapour and those gases might have turned into liquid form of water on the Moon surface.
“If liquid water and a significant atmosphere were present on the early Moon for long periods of time, we think the lunar surface would have been at least transiently habitable,” said Dirk Schulze-Makuch, an astrobiologist at Washington State University. Dirk Schulze-Makuch has also wrote the paper with Ian Crawford, a professor of planetary science and astrobiology at the University of London.
Scientists also believed that the Moon have been wrapped in a magnetic field that might have kept any life form living there safe from deadly solar winds. The earliest evidence of life on Earth comes from about 3.5 and 3.8 billion years old, in the form of cyanobacteria.
“It looks very much like the Moon was habitable at this time,” Mr Schulze-Makuch said. “There could have actually been microbes thriving in water pools on the Moon until the surface became dry and dead.”
The researchers are now looking forward that the claim will hopefully encourage NASA and other space agencies to undertake an “aggressive future program of lunar exploration”.
