Something strange is happening on Venus, experts don't know why

Earth is shielded by its protective magnetic fields, but not Venus

Scientists were baffled by the strange phenomena occurring in Venus as it spews different gases including carbon and oxygen into space with significant speed, reported Newsweek.

According to the study published in the journal Nature Astronomy, the speed is so fast that they can escape Venus’s gravity as was observed by the European-Japanese BepiColombo space mission.

Lina Hadid, author and a researcher at the Plasma Physics Laboratory at the Centre National de la Recherche Scientifique in France, said in a statement: "This is the first time that positively charged carbon ions have been observed escaping from Venus' atmosphere."

Earth is shielded by its protective magnetic fields as solar winds coming from the Sun can strip our atmosphere in space. Any such phenomenon is not present on the second planet of our solar system because of its cool core compared to Earth.

However, it has an "induced magnetosphere" forming after the charged solar winds enter its atmosphere and ironise the particles.

The spacecraft BepiColombo passed in 2021 for 90 minutes and observed this strange activity.

"These are heavy ions that are usually slow-moving, so we are still trying to understand the mechanisms that are at play. It may be that an electrostatic 'wind' is lifting them away from the planet, or they could be accelerated through centrifugal processes," Hadid said.

Now scientists consider this activity crucial to trace the evolution of Venus further.

It is dominated by 96.5% of carbon dioxide and 3.5% of nitrogen. There are also other gases such as oxygen and sulfur dioxide.

Venus is believed to be a place like Earth millions of years ago until its temperature became extremely hot — more than 864 degrees Fahrenheit.
