Sunlight falling through the clouds of Venus can support photosynthesis and make conditions ripe for life

0

Venus’ surface may be too extreme for it to survive, but sunlight coming through the planet’s thick clouds can aid photosynthesis, resulting in the existence of microorganisms, a new study suggests.

Researchers at California State Polytechnic University, Pomona have found evidence that photosynthesis, the process plants use to convert water and sunlight into food, can take place throughout the day.

It can even happen at night, due to the levels of thermal or infrared energy emanating from the planet’s surface and atmosphere.

Essentially, light energy would be available both from below and above the clouds, allowing potential microorganisms to live in different cloud layers.

The study comes just months after a separate group of researchers said the clouds on the planet are too dry and don’t have enough water to sustain life.

However, the study’s lead author, Rakesh Mogul, and the other researchers found that Venus’ clouds can be made in part from neutralized forms of sulfuric acid, such as ammonium bisulfate.

This would have higher water levels than described in the aforementioned study, making the clouds more palatable to life.

“Our study provides tangible support for the potential for phototrophy and/or chemotrophy by microorganisms in the clouds of Venus,” Mogul said in a statement. pronunciation.

“The acidity and water activity may be within an acceptable range for microbial growth on Earth, while the constant lighting with limited UV suggests that Venus’ clouds may be hospitable to life.”

“We believe that the clouds of Venus would be a great target for habitability or life detection missions, such as those currently planned for Mars and Europe.”

VENUS: THE EARTH’S SISTER WORLD

Venus and Earth are remarkably similar in size, but their histories differ.

The second planet from the sun is on the inner edge of the habitable zone, in fact, scientists believe it was habitable 700 million years ago.

A single day in the inhospitable world is 243 Earth days, compared to 24 hours on Earth.

It is a terrestrial planet that is similar to Earth in size, mass proximity to the sun, and bulk composition.

However, it has the densest atmosphere of the terrestrial planets, made up of 96% carbon dioxide and a surface pressure 92 times greater than Earth.

It has the hottest surface of any planet in the solar system with an average temperature of 867 degrees Fahrenheit.

The clouds are made of sulfuric acid, with acid rain falling on the hot surface.

It may have had oceans in the past, but the water would have evaporated as temperatures rose due to a runaway greenhouse effect.

Both NASA and the European Space Agency are sending missions to explore Venus, a planet dubbed “Earth’s evil twin.”

The solar and thermal radiation in Venus’ clouds has wavelengths of light that can be absorbed by the photosynthetic pigments found on Earth, the release said.

In addition, the study found that the sunlight coming through Venus’ atmosphere is stripped of most of its harmful ultraviolet radiation, similar to Earth’s ozone.

One of the study’s co-authors, Yeon Joo Lee, found that Venus receives between 80 and 90 percent less change in UV-A levels than Earth’s surface.

It is also ‘essentially depleted’ of UV-B and UV-C, which are considered the most damaging components of UV radiation.

‘We therefore speculate that microbial survival in an aerosol and water-confined environment could involve biochemical strategies to reduce vapor pressure and loss of water in the solution phase, similar to microbial strategies related to freezing point and temperature reduction, inhibition of ice. cloud formation and condensation,” the authors wrote in the study.

It’s unclear why Venus has significantly less ultraviolet radiation than Earth, but a study published in July found that winds reverse on Venus at night.

The study is published in the scientific journal Astrobiology.

In 2019, researchers said Venus may have had stable temperatures in the past and could have had “liquid water” for 2 to 3 billion years.

About 700 million years ago, it underwent a “dramatic transformation” – possibly due to volcanic eruptions – that completely changed the planet.

The surface temperature of Venus is 864 degrees Fahrenheit, compared to about 57 degrees for Earth

Venus currently has a surface temperature of 864 degrees Fahrenheit, compared to about 57 degrees for Earth.

In September 2020, scientists said they had found traces of phosphine gas in the clouds of Venus that may be indicative of life.

However, a study published in July said the phosphine may have come from the planet’s volcanoes and not from microbes living in the clouds.

CARBON DIOXIDE AND SULFURIC ACID DROPS IN THE ATMOSPHERE OF VENUS

The atmosphere of Venus is mostly carbon dioxide, with clouds of sulfuric acid droplets.

The thick atmosphere traps heat from the sun, resulting in surface temperatures over 470 °C (880 °F).

The atmosphere has many layers with different temperatures.

At the level where the clouds are located, about 50 km above the surface, it is about the same temperature as on the Earth’s surface.

As Venus moves forward in its orbit around the sun as it slowly spins backward on its axis, the highest level of clouds zips around the planet every four Earth days.

They are powered by hurricane-force winds at about 224 miles (360 km) per hour.

Atmospheric lightning bolts illuminate these fast-moving clouds.

Speeds in the clouds decrease with the height of the clouds, and on the surface they are estimated to be only a few miles (km) per hour.

On the ground, it would look like a very hazy, cloudy day on Earth, and the atmosphere is so heavy it’s like you’re a mile deep under water.
