Aditya-L1's VELC reveals asymmetric expansion of solar eruption, offering new insights into space weather

India, Nov. 3 -- India's first space-based solar observatory, Aditya-L1, has provided new insights into the expansion of coronal mass ejections (CMEs), helping scientists understand how solar eruptions evolve and potentially affect space weather, satellites and communication networks.

Scientists from the Indian Institute of Astrophysics (IIA), an autonomous institute under the Department of Science and Technology (DST), combined observations from Aditya-L1's Visible Emission Line Coronagraph (VELC), NASA's Solar Dynamics Observatory (SDO) and three-dimensional modelling to reconstruct the geometry and dynamics of solar eruptions.

The study, published in The Astrophysical Journal Letters, found that CMEs do not necessarily expand uniformly...
