Why in news
Astrophysicists using data from India's Aditya-L1 mission discovered that magnetic snaps power 93% of the solar corona's heat, solving a long-standing energy loss mystery.
Background
A team led by Prof R Ramesh of the Indian Institute of Astrophysics published findings in the Astrophysical Journal Letters. The study reveals that magnetic field lines snapping and reconnecting provide 93% of the corona's energy, while bubbling motions contribute only 7%.
Facts for Prelims
- S&TAditya-L1: India's first dedicated space-based observatory to study the Sun.
- FactMagnetic snaps and reconnection account for 93% of the solar corona's heat.
- S&TSolar Corona: The outermost layer of the Sun's atmosphere, which remains millions of degrees hotter than the surface.
