The Earth's twin brothers are destroyed by radiation

Radiation from a nearby dwarf has made the planet unable to live.

Kepler-438b planet destroyed by radioactivity of Kepler-438 dwarf

Universe scientists have just announced a sad new discovery. The planet of the size and most Earth-like environmental conditions ever found was no longer available.

Called Kepler-438b , the entire atmosphere of the planet has been destroyed by the massive radioactive waves emitted from a red dwarf star (Red Dwarf star) nearby - Kepler dwarf -438.

Normally, the superflare of red dwarfs occurs every few hundred days. The energy of these explosions is 10,000 times stronger than the Sun, equivalent to the power of 100 billion tons of TNT.

Due to the distance between Kepler-438 dwarfs and the Kepler-438b planet, the huge flow of energy from booms can only have a minor impact on Kepler-438b. However, the true risk factor lies inside the light streams. They are full of radioactive rays and deadly cosmic rays that form a mixture called 'aurora light'. The coronal mass ejection (CME) can erase the entire atmosphere and cause the entire planet to suffer from severe radioactivity, unable to live in The next thousand years.

Planet Kepler-438b is a planet outside the solar system that has the most Earth-like indicators ever found. Kepler-438b is about the same size and ambient temperature as Earth, but the distance between this planet and Kepler-438 dwarf is much closer than the distance from the Earth to the Sun.

Our Sun also emits a series of aurora of light but with a gentle and steady intensity, does not affect the Earth. Meanwhile, the Kepler-438 dwarf spits out a super strong aura every few hundred days.Kepler-438's aurora is more powerful than any other solar aurora ever recorded.

If the Kepler-438b planet has an external protective magnetic field similar to that on Earth, the planet will also be protected from the attack of aurora light. However, Kepler-438b does not have a magnetic field, or because the aurora is too strong, the entire atmosphere has been wiped out and contaminated. The entire planet has become an arid and harsh place where life cannot exist.

The auroral eruption is a phenomenon that occurs when a large amount of plasma is swirled and emitted from the star, creating huge electromagnetic winds with cosmic rays and radiation. Initially, electromagnetism will remove light air molecules such as oxygen and ozone into the universe. When there is no shielded atmosphere, the entire planet will be overwhelmed by deadly cosmic rays.
