Scientists are revealing new evidence of “dual” life on Earth

Several researchers have suggested that the ammonia gas in Venus’ atmosphere may be evidence of the possibility of living in it.

Researchers at the University of Cardiff, the Massachusetts Institute of Technology and the University of Cambridge have suggested that Venus, also described as the Earth’s “twin” because of its rock formation, may be a colorless gas containing nitrogen and hydrogen. “Ammonia”, a gas that can come from biological sources.

If there are any traces of ammonia, the scientists carried out a number of chemical reactions to show how a series of chemical reactions neutralize the surrounding sulfuric acid droplets.

This will lower the pH of the clouds from zero to -11, and even though it is still acidic, it is an indicator of the potential for life.

Astronomers and scientists have been studying ammonia in the upper atmosphere of Venus since the 1970s, especially since it was always believed that life forms could not live there because the planet is so hot.

“Any gas that is not in the environment is automatically suspicious because it came alive,” said Professor Sarah Seeker, associate professor of research at MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS).

Some researchers question this hypothesis, instead suggesting that gas may be caused by unexplained atmospheric or geological processes in Venus.

“It’s so exciting,” said David Greenspoon of the Planetary Science Institute in Tucson, Arizona, who has long promoted the possibility of living in the clouds of Venus.

“This may be the first study we have conducted to reveal an extraterrestrial biosphere on a planet very close to Earth, although the work requires follow-up,” he added.
