Mysterious "alien" forms on Venus have strange effects on the climate, according to scientists

Unexplained forms on Venus, some of which scientists have suggested are signs of a strange life, are even more mysterious than we thought. after a new groundbreaking study.

Scientists have known the dark "stains" on the surface for more than a century and they are changing over time. However, they were never explained and some researchers suggested that they could be evidence of life.

"It has been suggested that the particles that make up the dark spots are ferric chloride, sulfur allotropes, sulfur dioxide, etc., but none of them have yet been studied for their formation and absorption properties explain satisfactorily, "said Yeon Joo Lee, the lead author of the new report, in a statement.

Observations show that the particles in these dark spots appear to be the same size and behavior of the microorganisms found in the Earth's atmosphere. Along with other evidence, this has led some of the world's most famous scientists, including Carl Sagan, to speculate that the shady spots may be life.

Now researchers have learned more about how these clouds affect the planet's climate.

Researchers looked for changes in the "albedo" of the planet or how much it absorbs the light that hits it. They found that it seemed to be very different: Between 2006 and 2017, the amount of light reflected back into space was halved and then rose again.

These changes had a similar impact on the amount of sunshine absorbed by the clouds and therefore how much circulation there was in the planet's atmosphere. Strong activity could be observed in the atmosphere of the planet, with clouds swirling at a speed of more than 200 miles per hour, and could be explained by these changes in the clouds. These dramatic changes are happening.

"That's a remarkable result," adds Limaye. "It indicates that something is changing. We can see the brightness change. As the albedo changes, something drives these changes. The question is, what is the cause? "

These dark spots, so much speculated about, were termed" unknown absorbers "and could play a role in these changes.
