Is it likely that life ever existed on Venus?

To date, no definitive proof has been found of past or present life on Venus. With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.

Does phosphine exist in Venus?

Phosphine does not exist in the atmosphere. Venus is not a pleasant place: An extreme greenhouse effect ensures average temperatures of about 460 degrees Celsius on its surface.

Are there any organisms found on Earth that can produce phosphine?

On Earth, phosphine has been found in abundance in anaerobic (low in oxygen) ecosystems. It’s found in swamps and sludges, where anaerobic microbes thrive. Somehow, anaerobic microorganisms produce phosphine. And the clouds of Venus are anaerobic.

Why was the potential detection of phosphine in the atmosphere of Venus considered a possible signature of life?

Phosphine takes a fair amount of energy to create and is easily destroyed by sunlight or sulfuric acid, which is found in Venus’ atmosphere. So if the gas was produced a long time ago, it shouldn’t still be detectable.

What was the way of life in Venus answer?

​ Answer: With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet. …

How did we find phosphine on Venus?

In September, a team led by astronomers in the United Kingdom announced that they had detected the chemical phosphine in the thick clouds of Venus. The team’s reported detection, based on observations by two Earth-based radio telescopes, surprised many Venus experts.

What is the connection between phosphine gas and the possibility of life on Venus?

The detection of phosphine gas in the clouds of Venus—a possible sign of life—might be due to a fluke in data processing, new analyses suggest. Astronomers recently found a tantalizing hint that life could be wafting through the clouds shrouding Venus.

How did they find phosphine on Venus?

Where is phosphine found on Earth?

Phosphine is a chemical compound made up of one atom of phosphorus and three atoms of hydrogen, and scientists have also spotted it on Earth, Jupiter and Saturn. On the gas giants, it’s quite prevalent in the atmospheres, both of which are rich in hydrogen.

Is life possible on Venus because of Sulphuric acid?

This finding further indicates that most – but not all – cloudy planetary environments are not conducive to life. Hallsworth of Queen’s University, Belfast, said research “shows that the sulfuric acid clouds in Venus have too little water for active life to exist, based on what we know of life on Earth.”

Can a human survive on Venus?

Most astronomers feel that it would be impossible for life to exist on Venus. Today, Venus is a very hostile place. It is a very dry planet with no evidence of water, its surface temperature is hot enough to melt lead, and its atmosphere is so thick that the air pressure on its surface is over 90 times that on Earth.

Why can’t we find phosphine on Venus?

This is where the telescopes detected the signature of phosphine. But Venus’s atmosphere is so acidic, with clouds made of droplets of sulfuric acid, that any phosphine would be quickly zapped. For the gas to stick around, something must replenish the supply. Until now, phosphine has been detected only on three other worlds in the solar system.

Is phosphine the key to life on other planets?

Astrobiologists have flagged phosphine — a toxic compound of hydrogen and phosphorus — as a possible signature for life on other planets 2, and it is made by some organisms on Earth.

Is there life on Venus right now?

The phosphine discovery presents the tantalizing possibility that life might be on Venus right now. If this discovery is confirmed, which will likely require sending a spacecraft, we would know for the first time in human history that the solar system has two planets where life exists. In a cosmic sense, we wouldn’t be alone anymore.

Is there a toxic gas on Venus?

Venus’ clouds appear to contain a smelly, toxic gas that could be produced by bacteria, a new study suggests. Chemical signs of the gas phosphine have been spotted in observations of the Venusian atmosphere, researchers report September 14 in Nature Astronomy.
