Researchers find out why the “sister planet” of Earth lost all of its water.

Why the “sister planet” of Earth lost all of its water.

Scientists have delved deep into Venus’s past, bringing us closer than ever to solving one of the solar system’s mysteries.

Given their similar sizes, the planet is frequently referred to as Earth’s sister planet. It is thought that water formerly existed on the planet’s surface.

Huge volcanic plains now dominate the planet’s surface, and scientists have been puzzled and fascinated by the reasons behind this change for years.

But fresh research that was just published in Nature might be poised to alter that.
Proficient scientists have proposed the hypothesis that HCO+ dissociative recombination is the cause of Venus’s water loss.

In essence, this is a process wherein HCO+ ions combine with electrons to generate hydrogen and carbon monoxide, which subsequently escape into space.

This might have been coupled with a severe greenhouse effect, which would have happened as solar radiation increased and carbon dioxide levels rose, causing water on the planet’s surface to evaporate.
“This process nearly doubles the Venus H escape rate and, consequently, doubles the amount of current volcanic water outgassing and/or impactor infall required to maintain a steady-state atmospheric water abundance,” the researchers wrote in their paper regarding HCO+ dissociative recombination.

“In the wake of hypothetical late ocean scenarios, these higher loss rates would enable faster desiccation and resolve long-standing difficulties in simultaneously explaining the measured abundance and isotope ratio of Venusian water.”

Curtin University’s Martin van Kranendonk teaches geology and astrobiology. “Venus is not a nice place,” he claimed in an interview with Newsweek. In minutes, metal space exploration landers melt. The average surface temperature is 867 F.

This is due to two factors:

• 1) it is warmer because of its closer proximity to the sun than Earth.
• 2) it possesses a super-greenhouse atmosphere made up of 96% carbon dioxide.

“Life would actually boil to tar on the surface right now. Furthermore, Venus, the planet that is home to all life on Earth, naturally lacks water.”
