Scientists believe alien life forms could thrive in Venus clouds, nourished by acid-neutralizing chemical processes.

Researchers from Cardiff University, MIT, and Cambridge University believe the planet, 47.34 million kilometers from Earth, may have ammonia in its clouds.

Ammonia is a colorless gas made up of nitrogen and hydrogen.

While Venus is Earth’s nearest planetary neighbor, its harsh environment prevents human life from flourishing.

Sulfuric acid droplets—powerful enough to burn holes in your skin—fall from the planet’s clouds.

However, a new study by scientists from Cardiff University and Cambridge University in the United Kingdom and the Massachusetts Institute of Technology in the United States reveals that if ammonia is there, it might activate chemical reactions that could support life on Venus.

The researchers used a computer simulation to show that ammonia would trigger a chain reaction to neutralize sulfuric acid droplets in the vicinity.

The acidity of the clouds would then reduce from -11 to zero, and while this is still highly acidic on the pH scale, it would be at a threshold where life might theoretically live, 9News reported.

“We know that life can grow in acid environments on Earth, but nothing as acid as the clouds of Venus was believed to be,” co-author of the study William Bains, from Cardiff University said.

“But if something is making ammonia in the clouds, then that will neutralise some of the droplets, making them potentially more habitable.”
