Why in news
Researchers at the Indian Institute of Astrophysics (IIA) developed a 3D simulation model to predict Coronal Mass Ejections (CMEs) to protect satellite infrastructure and power grids.
Background
The Indian Institute of Astrophysics (IIA) collaborated with international partners to create a 3D computer simulation model. The model traces magnetic flux rope buildup and energy release, validated using NASA’s HMI and AIA instrument data.
Facts for Prelims
- S&TCMEs (Coronal Mass Ejections) are eruptions of magnetized plasma from the sun's corona.
- BodyIndian Institute of Astrophysics (IIA) is a premier research institute in India.
- S&TNASA's HMI (Helioseismic and Magnetic Imager) and AIA (Atmospheric Imaging Assembly) are instruments used for solar observation.
- FactThe study was published on August 16, 2026.
