The deadly truth on the 'twin' planet orbiting Earth

Some recent studies suggest that there is another green planet once present besides Earth. But new evidence suggests it could be a hellish version.

A team from the Moon and Planet Institute (LPI - USA) has found evidence of "hell rivers" on Venus, rejecting the theory of a planet once as green as the earth that many scientists Another school pursued recently.

Specifically, they identified what was found on Venus's Ovda Regio plateau not as granite as previously thought, but as basalt.

The team agrees somewhat with earlier evidence that Venus once had a dynamic array of activities like Earth, and the plateau was shaped like an earth - the tectonic plates are pressed together. , rising into a hill. And so the nature of this plateau may represent what was once present on most of Venus' surface. These are not rivers, streams, or oceans filled with water. It 's lava, which makes basalt when cooled.

So it can be said that if any liquid ever flowed on Venus, it was just hot lava flows.

The research, led by Dr. Allan Treiman, has just been published in the Journal of Geophysical Research: Planets.

Earlier this year, some scientists came up with evidence that in the early days of the Solar System, Venus also had Earth-like oceans and a favorable environment for life.

The most prominent is a study from NASA's Goddard Space Flight Center, published at the 2019 Lunar and Planetary Science Conference, showing that Venus once rotated a lot faster than it is now, with a surface mostly composed of stars. Yang like Earth. But over time, it was strongly influenced by the gravity of the Sun, leading to violent tides that slow the planet's rotation. Since then the oceans have evaporated, Venus gradually became hot and dead.

Venus is the second planet from the sun, but with a temperature of 462 degrees Celsius, it is currently hotter than the nearest planet, Mercury.
