A group of astronomers has just announced incredible news, and perhaps one of the most important discoveries in decades has been announced that it may be the proof of life for another Venus.
How does Venus live? And are we excited about this announcement?
The team used Alma and another telescope called just to find that the atmosphere of Venus has the absorption characteristics of the chemical symbol PH3 phosphine molecules, which is actually the key to everything. This is the common identity of life!

Today’s news marked an exciting day with the announcement of biochemical markers in the atmosphere of Venus, and for many of us who have searched for Mars as our best bet for life in the solar system, it’s exciting, perhaps Surprising. In fact, compared with Venus, which only the Soviets have ever landed on, NASA has invested more energy in the orbiter, lander, and rover on Mars. The reason is simple. The surface temperature is 460 degrees Celsius. , Enough to melt lead, and the surface pressure is similar to one kilometer below the seafloor.
The challenge of Venus's life is the composition of the atmosphere. The atmosphere is almost entirely composed of carbon dioxide, while the clouds are highly acidic composed of sulfuric acid. Now, most life on the earth almost immediately dies under such acidic conditions, but in fact, some microorganisms on the earth actually rely on the acid called acidophilus to grow. Now this acidophilus, like other extreme thermophiles, is the product of billions of years of evolution. They have highly complex molecular mechanisms inside. To deal with these conditions, so if life really exists, the Venus cloud.
The latest simulation work by Michael Way and Anthony Dungeolino shows that Venus can keep water liquid for about 3 billion years, and it became uninhabitable only 750 million years ago. At the same time, the occurrence of global resurfacing events also heralds volcanoes. The catastrophic event that broke out is a very bad time for life on Venus.
If we use phosphine as a biomarker and undergo safety testing by the team, it means that we have not actually seen direct evidence of life on Venus, because phosphine is actually produced by life, But it may also be produced by things unrelated to life, such as geochemistry or photochemistry, which only means that light interacts with chemical substances.
