US scientists have built the "sun" in the laboratory

The sun - is the source of the existence of all life on our planet. Were it not for the sun, and there would be no life. However, despite the fact that astrophysicists around the world have long been studying the structure of the main star of our planetary system, many of the processes occurring inside the Sun are still shrouded in mystery. To better understand how to construct a star, a team of American scientists has constructed in his laboratory, "The sun in miniature."

Why build an artificial sun

Installation was named Big Red Ball and it is designed to generate and simulate the behavior of the solar plasma. He is responsible for the development team from the University of Wisconsin-Madison, led by physicist Cary Forester. As reported by researchers at interview Nature Physics, reaction generated inside Big Red Ball, can mimic the characteristics of the magnetic field of the sun. This will allow to recreate the events that had never before seen on Earth.

For the most part, Big Red Ball models the only part of the phenomena that come within the Sun, however, observe what is happening with the solar plasma, but in a smaller scale, will help shed light on the origins and mechanics of operation of such phenomena as For example, the solar wind.

This work is incredibly exciting - says Elizabeth Jensen, a physicist working in a team Big Red Ball. The sun is still surprisingly poorly understood. A larger one of the puzzles is how the solar wind, the flow of charged particles and the plasma gas which flows from the sun's surface with extremely high velocities.

How does the artificial sun

In general Big Red Ball is a hollow filled with helium plasma, a three-meter scope. In the center of the device is set extremely powerful magnet system for generating a magnetic field. In fact the Big Red Ball repeats the structure of the Sun, but in miniature. The most interesting thing started at a time when scientists tested the installation.

This is interesting: As our sun dies?

to restrain the power of their internal magnetic core particles are mostly moving in a confined space sphere rotating around the center. But when the rotation reached a speed of 22,000 miles per hour (about 35, 5 thousand kilometers per hour), the plasma escaped beyond the sphere with great speed.

"This is a critical threshold is the point at which the plasma has gained enough energy to overcome their magnetic limit. The released particles have their internal magnetic field, allowing them to pick up speed. Modeling has shown us a simplified version of how well the solar wind, it is possible to overcome the attraction of the sun, which (especially in the stars the equator) is very strong. "
