 With the use of powerful telescopes, scientists were able to find phosphine the atmosphere of Venus which is a possible sign of life since phosphines are released when organic material break down.
 Other than that Venus has a pretty harsh environment: temperatures can reach a high of 426 Celsius, and the atmosphere is covered with other toxic gases. Thick clouds cannot let enough sunlight into the surface and it rains sulfuric acid. Researchers also think that the phosphine gas production could also be a result of geological factors.
 Even after all these, scientists think that some microbial life can survive in Venus and they also say that only geological processes are not capable of producing significant amounts of phosphines so there must be some form of life there. It is also argued that “coupled iron- and sulfur-centered metabolism in the clouds” can also help microbes survive there.
