Astronomers have discovered a gas that they believe is phosphine, which on Earth comes only from living organisms.
Phosphine is found in the stomachs of penguins and can also be produced in factories. But there are neither factories nor penguins on Venus, as the BBC writes.
Astronomers have investigated how the gas could arise without a connection to living organisms, but so far are stumped. Therefore, it may be that life exists on Venus.
Venus is not a nice place.
It is 470 degrees hot on the surface, with an atmospheric pressure 90 times higher than on Earth. It is about the same pressure as a kilometer into the sea. Do you think it's sad when it's raining here on earth? On Venus it rains sulfuric acid.
A human would not survive more than a few seconds on Venus.
But maybe there is something that lives there? If it turns out to be true, it is one of the greatest discoveries in human history.
