Scientists have made a shocking discovery behind the spectacular light shows every time Earth is exposed to cosmic fireworks from its angry parent star.
According to the sheet Space, a type of aurora called “isolated proton aurora” revealed that the cause of ozone depletion comes from space. They come from fruit “cosmic cannon” with plasma that the Sun regularly projects and occasionally strikes the Earth.
An international research team led by Dr. Mitsunori Ozaki from the Graduate School of Natural Sciences and Technology at Kanazawa University in Japan studied these powerful plasma streams and found that they not only create the northern lights, but sometimes “hole” upper layer of the earth’s ozone layer.

These holes are up to 400 km wide, located in the middle layer of the atmosphere and, fortunately, do not last forever.not. At the holes, the ozone almost completely disappeared in about 1.5 hours, then recovered.
Although it heals much more quickly than the stratospheric ozone hole – caused by humans – its impact is enough to affect the Earth in other ways.
Without the protective layer, harmful radiation from the Sun will be able to penetrate deeper, which could cause problems with electrical and telecommunications infrastructure. Previously, the charged particles contained in these space guns en route to “landing” in the atmosphere could also have a negative effect on astronauts and satellites operating in higher areas.
According to the authors, the plasma cannons pierced the sky in a way that sent charged particles into the magnetic field lines of Earth’s magnetosphere. Nitrogen and hydrogen oxides released due to particle interactions with the atmosphere have depleted the ozone layer.
This discovery will help scientists have more basis for predicting fluctuations in space weather, which is very important in many modern technological activities, especially in the telecommunications and aerospace industry.
The research has just been published in a scientific journal Scientific reports.
