- Scientists discovered that the Sun’s upper atmosphere rotates faster than its visible surface, challenging the expected behaviour of classical physics.
- The study was conducted by Aryabhatta Research Institute of Observational Sciences (ARIES), Uttarakhand, Udaipur Solar Observatory (USO), Physical Research Laboratory (PRL) and Ahmednagar College.
- Researchers used data from the Nobeyama Radioheliograph, Japan and applied a 2D image-correlation method to measure solar atmospheric rotation.
- The study found that the Sun’s rotation speed increases with height above the solar surface and slightly decreases during periods of high solar activity (more sunspots).
- The findings help improve understanding of solar activity and space weather, which can affect satellites, communication systems, navigation networks and power infrastructure.
