How India’s Aditya-L1 and Europe’s Proba-3 studied solar eruptions together
Researchers have successfully combined data from India's Aditya-L1 and the ESA's Proba-3 missions to study coronal mass ejections (CMEs) near the Sun. This collaboration provides new insights into the mass, density, and energy of solar eruptions during their earliest stages.
Why it matters
Improved tracking of solar eruptions is critical for predicting space weather, which can significantly impact satellite communications and power grids on Earth.
The Sun may look steady from Earth, but its outer atmosphere is a theatre of violent eruptions that hurl vast quantities of material into space. Understanding how these eruptions begin and develop matters for the study of space weather and its effects on the environment around Earth. Observing them close to the Sun, however, has long been a challenge.For the first time, researchers have jointly analysed observations of the same coronal mass ejections (CMEs) recorded by India’s Aditya-L1 mission and the European Space Agency’s (ESA) Proba-3 mission.The team examined two eruptions seen on September 14 and 16, 2025. The first travelled at around 645 km per second, while the second moved at about 145 km per second.
