'The black hole in the sky' drains the Earth's neighbor's ocean?

New research from a group of Russian and German scientists has come up with a new explanation for the aridity and death of Mars, a neighbor who has been shown to have oceans like Earth. It was a giant hole that appeared between its atmosphere and "gluttonous" like the black hole in the universe.

According to a recent publication in the scientific journal Geophysical Research Letters, the researchers believe that Mars once possessed a vast super ocean, quite similar to the "supercontinent" Earth, but rather smaller. a lot of. Every two years, the mysterious "black hole" appears in the atmosphere once and sucks a portion of the ocean's water, throwing it into space. A small portion of the remaining water is returned to the planet's poles.

After billions of years, this process was slow but enough to make the planet red dry.

To reach this conclusion, the research team led by scientist Dmitry S. Shaposhnikov (from Moscow Institute of Physics and Technology and the Russian Space Research Institute) investigated the exoticness of water on Mars. . Previous studies have shown that Mars has high levels of water vapor in the atmosphere and they tend to move to the planet's poles. This is difficult to understand because the data about a planet's middle atmosphere indicates that it seems to stop completely the water cycle. It is too cold to maintain steam.

However, that mysterious hole opened in the summer in the southern hemisphere of Mars, when the area approached the sun. This happens every 2 years according to Earth time. The hole appeared at an altitude of about 60-90km, bringing steam from below the middle of the cold atmosphere, going straight up to the upper floor. The process has the support of giant dust storms - which killed NASA's famous Mars Curiosity Rover.

But when escaping high, only part of the water escaped, drifting to the North and South poles. Most of the remaining water molecules are severely ultraviolet light cut off the hydrogen-oxygen bond. Hydrogen flew out into space, leaving only oxygen remaining. And so, it is no longer a water molecule.
