Astronomers from the Indian Institute of Astrophysics (IIA) observed that the Sun has been quieter and cooler between 2008-2019 as compared to 1996-2007. The scientists found that the Coronal Mass Ejections (CME) from 2008-2019 has significantly decreased in size, mass as well as internal pressure. CMEs are the massive solar particle eruptions due to intense flares from the sun.
