Explain the mystery of the halo at dawn

Scientists may have explained the long-standing mystery of the origin of the energy particles creating polar halo at dawn.

Electrons create light rays at dawn - also known as northern and southern light - that may have been accelerated to extremely fast speeds at the magnetosphere of the earth, a new study has just explained. . The region is 1,000 times larger than the level scientists thought, providing enough volume to create a lot of very fast moving electrons.

Jan Egedal of Massachusetts Institute of Technology (USA) and his colleagues analyzed data collected from spacecraft and used Kraken supercomputer simulations.

The Kraken has 112,000 processing equipment. The team used 25,000 processors in 11 days, tracking the movement of 180 billion particles in the universe to draw out how the motion of electrons creates aurora rays.

The researchers determined that these electrons could very well be energized to accelerate in the magnetosphere and then pushed away in the universe by the solar wind.

The solar wind, the flow of charged particles released from the Sun's upper region - stretches the lines from the earth's field like a stretched rubber band. When parallel magnetic lines are reconnected, the released energy is like a rubber fiber released, and the electrons are pushed back to Earth at an extremely fast rate.

When fast-moving electrons collide with molecules in the upper atmosphere of the earth, creating a phenomenon that we often call polar aura.

In addition to creating very beautiful scenes in the high latitudes of the earth, these energetic electrons can destroy or damage the spacecraft.
