gas called phosphine was found in the hot and toxic atmosphere of Venus,

 In 2020, scientists reported signs of phosphine in the clouds of Venus, a harmful gas associated only with life on Earth. Phosphine consists of three atoms of phosphorus and hydrogen that quickly break down in the oxygen-rich atmosphere seen on Earth. The study, now published in the journal Proceedings of the National Academy of Sciences, argues that Venusian is likely a volcanically erupted phosphide as an abiotic source of phosphine.

 

let's talk about atmosphere on venus:

Venus is often referred to as Earth's twin. It's a sister planet with some interesting quirks.

One main difference between Venus and Earth is the temperature on Venus, where it ranges from 462 degrees Fahrenheit to 864 degrees Fahrenheit. The atmosphere on Venu has 90% carbon dioxide (CO2) compared to the air we breathe which is roughly 80% nitrogen and 20% oxygen (N20).

Although this may sound like a pretty drastic difference in the air, there are several factors that help to prevent Venus from being completely uninhabitable.

First, the atmospheric pressure on Venus is about 100 times greater than Earth's at 90 bar compared to our 14.1 pascals of pressure on the surface of the Earth. However, since there is so much CO2 in the atmosphere, it's difficult for humans to successfully venture into space without special gear (which isn't too hard to obtain).

A main feature of the surface is Venus' mountains, which are about five to six miles high. The atmosphere on Venus is also comprised of clouds. There are two main types of clouds; thick and thin. The thick clouds are made up of water droplets and sulfur compounds which result in the white color of the planet while the thin clouds contain droplets of liquid hydrocarbons which give the planet an orange glow.
