New signs of alien life revealed near Earth

(NLDO) - Evidence of alien life on Earth's "evil twin" has just been reinforced by a new discovery.

A few years ago, the unexpected discovery of phosphine - a gas closely related to life on Earth - in the clouds of Venus caused controversy.

One of the main reasons is that the phosphine signal is so faint that even some subsequent observations did not detect it.

But now a team of scientists has not only proven the existence of phosphine on Venus more clearly than ever before, but also found another potential "biosignature."

According to Dr. Dave Clements from Imperial College London (UK) - a member of the research team, this time they used the observational power of the James Clerk Maxwell telescope located in Hawaii - USA.

This allowed them to collect 140 times more data than previous studies. They again found signs of phosphine, but much more clearly than before, according to CNN.

Not only that, signs of ammonia also appear.

The presence of phosphine and ammonia in the atmospheres of gas giant planets such as Saturn, Jupiter... is not strange. Because gas planets have hydrogen-rich atmospheres, compounds containing hydrogen radicals are of course common.

But on rocky planets like Earth, Venus or Mars, there is enough oxygen to "capture" the hydrogen radicals.

Therefore, the presence of phosphine (PH ₃ ) or ammonia (NH ₃ ) on rocky planets are potential biosignatures. These gases can be emitted by living things or as a result of the decomposition of plants and animals.

Professor Jane Greaves from Cardiff University (UK), a co-author, said they would use the ammonia discovery as the basis for a separate scientific paper, using additional data from the Green Bank Telescope in West Virginia.

The findings once again support the hypothesis that Venus is indeed a planet where life has a high chance of existing.

This planet has long been thought to be a twin of Earth, but an "evil twin" because the unfortunate planetary evolution has caused it to sink into a harsh greenhouse effect, the temperature becomes very hot, rotates very slowly and the atmosphere is full of sulfuric acid.

However, it is an undeniable fact that Venus is still a planet in the Solar System's Goldilocks habitable zone.

It is also one of the most favorable worlds to study, since Venus is the closest planet to Earth.
