[4] Are There Rings Around the Sun? Observations: Parker Solar Probe NASA’s Solar Probe found Tantalizing Evidence of Rings Around the Sun by Becky Ferreira 05 December, 2019 The parker Solar Probe captured evidence of a passible dust-free zone, hinting at rings, along with insights into “magnetic islands” and plasma “blobs” These weird solar features are described in one of four new papers published in Nature on Wednesday, based on dispatches from a record- breaking NASA space craft called the Parker Solar Probe.

Rawal was born in a Gujarati family, in Halvad village at Morbi district, of Gujarat. He received an M.Phil degree in Physical Sciences, from Calcutta University, in 1975, and a PhD degree in Astrophysics, from the University of Mumbai, 1992 (Thesis: Some Problems in the Solar System & in the Local Group of Galaxies). He was also associated with Children Science Congress activities popularizing scientific interest among school children in many Indian States.
