Scientists develop a 'mini sun' to study solar wind

Jul 30, 2019 16:21 IST


To get a better understanding of solar winds, scientists at the University of Wisconsin-Madison built a 'mini sun' that mimics the real sun. Dubbed the 'Big Red Ball', researchers pump in helium gas, just like its present in the actual sun, and turn it into plasma. Moreover, a magnet present at the centre also creates a magnetic field when electric current is applied to the machine. The research published in the journal Nature Physics said that the object will help scientists study how solar wind is generated and how it transforms as it travels to the earth.
