Sun's Upper Atmosphere Rotates Faster than its Surface
Background
A recent study by Indian scientists has revealed that the Sun's upper atmosphere rotates significantly faster than its visible surface (Photosphere). This remarkable finding challenges the traditional understanding of the rotational behaviour of gaseous celestial bodies and provides new insights into solar physics. The research was carried out by scientists from institutions supported by the Department of Science and Technology (DST), Government of India, and has been published in the prestigious journal Astronomy & Astrophysics Letters.
