Phosphine is a colourless gas that smells somewhat like garlic, or decaying fish
On Earth, it is produced naturally by bacteria or the decay of organic matter
Experts led from the UK have found traces of the gas in the clouds above Venus
Unlike on the planet's surface, conditions in the upper cloud layer are Earth-like
However, experts have warned that there could be other sources for the gas

Traces of phosphine gas detected in the clouds above Venus could be an indication that the planet supports microbial life, a study has concluded.

On Earth, phosphine — a colourless gas that smells like garlic, or decaying fish — is naturally produced mainly by certain microorganisms in the absence of oxygen.

It can also be released in small amounts from the breakdown of organic matter, or industrially synthesised in chemical plants.
Experts from the UK, however, found signs of phosphine in Venus' atmosphere — suggesting the planet must support unknown chemical processes, or even life.

The second-closest planet to the Sun, Venus is inhospitable — with a surface temperature around 867°F (464°C) and pressure 92 times that of on the Earth.

However, its upper cloud deck — 33–38 miles (53–62 kilometres) above the surface — is a more temperate 120°F (50°C), with a pressure equal to that at Earth sea level.

The clouds are also highly acidic — meaning that the phosphine would be broken down very quickly and must therefore be being continually replenished.

The researchers have cautioned, however, that life is only one possible explanation for the source of the phosphine — with further investigation needed.

NASA is presently considering two missions to Venus that propose to study the planet's atmosphere and geochemistry — dubbed 'DAVINCI' and 'VERITAS'.
