NASA also believes that nothing can live on Earth 2

The second earth once gave a lot of hope, but it seems hope now collapses.

In August 2016, the European Space Research Organization in the Southern Hemisphere (ESO) announced a planet likened to Earth's twin brothers: Proxima Centauri b.

This planet meets all the elements to bring hope of human migration in the universe, such as in the Goldilocks region - the area is not too far nor too close to the star, enough for the planet to maintain liquid water. . Moreover, Proxima b has a distance that is considered to be extremely close - "only" 4.5 light years only.

Proxima b - Earth's brother.

However, there was an opinion that Proxima b could not stay. And according to a recent calculation model from NASA, it seems that this planet is really a dead land.

You know, being in the Goldilocks area does not guarantee that the planet has an ocean on its surface.

If there is no medium enough atmosphere, water will not be able to hold. And if the atmosphere is too thick, the planet's temperature is also terribly high.

But not enough."If you want to find a planet that can grow and sustain life, we need to determine which star is capable of nurturing it," said Vladimir Airapetian of NASA's solar energy group. That is, if the stars are too powerful, it will generate storms that are enough to deplete a planet's atmosphere, making it impossible to survive.

Based on this factor, red dwarf stars such as Minority (Proxima Centauri's master b) suddenly become bright candidates to seek life. The reason is because these are small muscle stars, the mass is only half of our Sun, and the surface temperature is slightly cooler - about 4,000 degrees Celsius.

However, NASA's new model has caused all hope to be extinguished." Red dwarfs often emit explosions from the field, more than the Sun, " said William Danchi, a member of the research team.

Magnetic field storms emitted by red dwarfs are stronger and more frequent than the Sun.

Magnetic explosions release a huge amount of energy, breaking atmospheric molecules on the surrounding planets into atoms and ionizing it. Air ions will disappear over time, and then the atmosphere will collapse. So there is no atmosphere, no water!

Applying this study to Proxima b and Subtle, NASA concluded that the planet had lost almost all the oxygen molecules in the air about 10 million years after its formation. In addition to the magnetic field storms produced by Subtle, it is clear that Proxima b is no longer an ideal place for life to flourish.

The study is published in Astrophysical magazine.
