Scientists uncover origin of Sun's grass-like plasma jets
A NASA-funded study has uncovered the origins of Sun's swirling spicules, grass-like plasma jets which can go upto 10,000 km from the Sun's surface. Scientists simulated the short-lived jets and found they are formed when charged particles bound by magnetic fields are hit by neutral particles. Scientists believe the spicules are responsible for heating Sun's atmosphere and propelling solar wind.
