A ray of hope as scientists found existence on VENUS
In the fall, a group of scientists made a sensational case. They said that they had found convincing evidence that shows life existing in the clouds of Venus.
That’d be beautiful if it were real. People have been looking at the stars for a long time and thought anyone out there is living. It would indicate that life is not unusual in the cosmos, but regular, for an affirmative response to turn up on the world in motion next to Earth.

With their instruments on Earth, the scientists, guided by Jane Greaves of Cardiff University in Wales, did not have any microscopic Venusians. Instead, they announced the discovery of a molecule called phosphine in a paper published in the journal Nature Astronomy and said they’d show back with no reasonable reason for how that could form there but rather as the waste material of microbes.
Five months later, experts are not entirely what to expect of the results and what that might mean, after unforeseen twists and nagging suspicions. In the study of Venus, it could spur a revival that has been widely neglected for decades. Exotic volcanism and current historical puzzles may be found out. Indeed, it may be aliens. If at least, it may be nothing.
Even if they have reduced their figures of how much phosphine is there, Greaves and her coworkers remain confident of their results.
The detailed information on this research
Most are suspicious, if not refusing to believe, in the larger community of planetary scientists. Some assume the signal is just a noise wiggle, or that sulfur dioxide, a chemical believed to be in the environment of Venus, might explain it.
For ages, the controversy may continue, unanswered, just as earlier contested arguments for the proof of existence on Mars. Gilmore is the lead researcher of a report that has suggested to NASA an extensive robotic “flagship” mission to Venus that will involve a 60-day airship flying thru the clouds.
Stats about Venus and life on Venus
Today, Venus’ layer is a terrifying location where temperatures are roasting well above 800 degrees Fahrenheit. Early in the evolution of the solar system, with seas and a mild atmosphere, it may have been even more like Earth today.
Mars, which is now hot and snowy, still seems to have had water running over its surface during this early period. Conceivably, we had habitable worlds on Venus, Earth, and Mars 4 billion years ago. “And we recognize that our world already has a functional, growing biosphere. And it was too high on Venus. It was too cold on Mars.’
Yet life tends to hang on stubbornly until it emerges, living in harsh surroundings.
Some scientists claim that it is probable for Mars to continue living underground, in the soil, today. But the subsurface of Venus is too hot, said Schulze-Makuch, who investigated whether a specific part of the Earth was still viable 20 years ago.
Venusian life should have gone up into the sky. There are short-sleeve conditions of around 85 degrees Fahrenheit, thirty miles up. Microbes will remain aloft at that level over several months in that portion of the environment, and enough to replicate and sustain a sustainable population.
Availability of phosphine on Venus

Even the skies, though, are not a serene and benevolent location. They are packed with sulphuric acid particles and showered in the sun’s heat. And it is dry, with just smidgens of water, as we know it, a necessary element for survival.
Phosphine is a simple compound, a pyramid of three hydrogen atoms bound to a single phosphate atom. But moving the atoms along requires tremendous energy, and circumstances for this kind of chemical reactions don’t even seem to occur in Venus’ atmosphere.
Phosphine is created on Earth by microbes that survive despite oxygen. It is present in our intestines, in badgers’ and penguins’ feces, and even in some deep ocean larvae.
The loud wiggles along the phosphine absorption line were reduced when the composted ALMA data was available in November. However, there still seemed to be less phosphine, around 1 part per billion total, with locations that could be as high as five parts per billion.
Here’s what recent studies have to say about the atmosphere on Venus

A recent paper by a group of scientists suggests that a more accurate model of the environment of Venus established in the 1990s reveals that a visible absorption line from Earth does not even produce phosphine in the cloud layer.
To absorb the sun, the team discovered that the phosphine would have to be about 15 miles higher. Nevertheless, researchers analyzing data from Venus Express, a spacecraft of the European Space Agency that orbits the Earth Venus from 2006 to 2014, found phosphine null.
So did observers who, from a NASA telescope in Hawaii, we’re attempting to try a particular phosphine absorption line in ultraviolet measurements. Phosphine amounts, if they are present, may also shift over time. That will make conclusive solutions more complicated to keep coming up with, just like methane’s continuing uncertainty on Mars.
