Researchers believe that there could be potential lifeforms producing ammonia in the clouds of Venus that are “very unlike anything we’ve seen”.
The colourless gas, a compound of nitrogen and hydrogen, could be indicative of chemical reactions that would make the planet – 47.34 million kilometres from Earth – more habitable to alien life.
Venus itself is so hot that it is inconceivable to have life forms, and if there is life in the clouds it is likely to be microbes like Earth bacteria – albeit with a chemical composition unlike that we have seen on our planet, or even neighbouring planets like Mars.
This is because life on Mars is more likely to be similar to that on Earth and so scientists have a greater idea of what to expect. Venus, in contrast, is unlike any other planet in the solar system.
