Mini Sun: US scientists recreate the 'Sun' in their laboratory to study solar winds

India may be developing to send a probe to Sun to study solar winds, but US scientists have recently built ir own "mini-sun" in University of Wisconsin-Mison for same purpose, as per international reports.

reports say that team developed miniature Sun- ' Big Red Ball', to study how actual Sun's magnetic field influences entire solar system. team has published its findings in Science journal - Nature on Monday.

Aim of 'Sun' study

According to study, team explains how interaction between Sun’s magnetic field and solar wind creates a magnetic structure, kwn as Parker spiral which is integral in sustenance of our Solar system. 

"While satellite missions have documented pretty well where fast wind comes from, we were trying to study specifically how slow solar wind is generated and how it evolves as it travels toward Earth," stated Ethan Peterson, le author on study in a press release.

How did y recreate 'Sun'?

y furr explain how y tried to replicate system to study its effect by pumping helium gas into ir 'Sun' to turn it into plasma along with placing a magnet at center of 'Sun' to create a magnetic field. 'Big Red Ball' which is 3 metres wide was subjected to an electrical field, creating an electromagnet similar to actual sun's plasma and magnetic fields.

What did y observe?

team has observed that ir ' Big red Ball' system mimicked in laboratory can be used for studying solar wind dynamics just like NASA’s Parker Solar Probe mission. y reached this conclusion as y found that magnetic field induced in ir spiral ejected 'quasi-periodic plasma blobs' which was similar to plasmoids observed on actual Sun, thus fuelling slow solar wind.

Meanwhile, NASA's Parker Solar Probe is currently circling Sun observing solar wind to study same effects on ground. India too is planning its solar mission itya L1 to answer ISRO's question - 'How corona gets heated to such high temperatures?'
