A new report by NASA has proven that aliens could be living in the acid clouds of Planet Venus.
A NASA investigation report on Venus, the sixth largest planet in our solar system, claimed that microbial life forms may be living in the upper atmosphere of the planet, which is rich in sulfur dioxide.
The research paper was titled ‘Venus’ Spectral Signatures and the Potential for Life in the Clouds.
Some mysterious dark patches were found to be similar to Planet Earth’s light-absorbing properties of bacteria. The report found that the planet has “moderate temperatures and pressures (∼60°C and 1 atm)” which are “favorable conditions for microbial life”.
NASA had sent in their space probes, which have detected such properties on the second planet from the Sun.
Sanjay Limaye, the research and project leader, said, “Venus shows some episodic dark, sulfuric rich patches, with contrasts up to 30-40 percent in the ultraviolet, and muted in longer wavelengths,”
He added, “These patches persist for days, changing their shape and contrasts continuously and appear to be scale dependent.”
Sanjay Limaye is from the University of Wisconsin-Madison’s Space Science and Engineering Center, and has authored and co-authored more than eighty papers on planetary research.
However, the report also said that these ‘mysterious patches’ could turn out to be only space-algae blooms, which are also found in ponds and lakes.
Venus, which has the longest rotation period in our solar system, is dubbed as ‘Earth’s evil twin’ and has been known to be inhospitable for life.
“On Earth, we know that life can thrive in very acidic conditions, can feed on carbon dioxide, and produce sulfuric acid,” said Professor Rakesh Mogul, one of the co-authors of the paper.
The clouds on the planet are completely opaque, reflecting almost 75 percent of sunlight, and produce only acid rain.
Many years ago, however, the planet was hospitable for life, with water being found on its surface for 2 billion years, which was “much longer than is believed to have occurred on Mars.”
The report concluded by saying that further investigation of the planet is required. “Our comparative analyses support the blended hypotheses that terrestrial-type biology can survive within and contribute to the spectral signatures of Venus’ clouds.
“To test the ideas presented here, we propose the need for an integrated chemical, biochemical, and microbiological study focusing on the survival and spectroscopy of terrestrial microorganisms under Venus’ cloud conditions.”
It also said, “Looking forward, investigations into the actual habitability of Venus’ clouds would ideally benefit from a mixture of an orbiter, lander, airplane/balloons, and sample return missions.”
“For future flagship endeavors to Venus, these types of instruments could potentially be incorporated into missions focused on planetary geology or atmospheric chemistry, while simultaneously providing key insights into the potential habitability of the clouds.”
