There is a new study that shows that many exoplanets might actually have many toxic gases in their atmospheres. If this is true, it might be hard for complex life forms to evolve.
There are 7 Earth-sized planets in the TRAPPIST-1 system. Three of those are placed in a habitable zone, but the atmospheres of those are full of gases. We don’t know if they are safe.
Is there life in the universe?
There is one question to which we cannot answer: how common is life in the universe? Various research shows that there should be both planets and moons that are capable of supporting a kind of biology. But how about life? There is a new study that shows that the worlds out there are evolved and that the life forms are actually fewer than some people believe.
Why is it difficult for life to evolve?
Findings from researchers at the University of California Riverside show that many of the planets have toxic gases in their atmosphere. This thing makes it difficult for life to exist. This marks the first time the physiological limits of life on Earth are cataloged as being able to predict the distribution of life in the universe.
The findings also showed some things about the habitable zone, as well. This one is a region around a star, where the temperature allows the water to exist on the surface of a planet that is full of rocks. The high level of the toxic gases could actually get rid of the planet in some cases.
Let us take it this way
We have a habitable zone, that is a safe zone, and it can support rich ecosystems like those on Earth.
However, the results show that ecosystems just like ours from the Earth cannot exist in most of the regions, as they previously thought.
