India’s Aditya-L1 Mission Captures First Images of Coronal Mass Ejections,
New Delhi – India has entered the exclusive club of nations observing our Sun with the launch of Aditya-L1, its ambitious solar exploration mission.** The special spacecraft, named after the Hindu Sun god, is already making waves with its groundbreaking observations. Aditya-L1 recently captured the moment a massive coronal mass ejection (CME) erupted from the Sun’s outermost atmosphere, providing valuable insights into these powerful solar events that can have a significant impact on Earth.
"These CMEs," explains Dr. R Ramesh of the Indian Institute of Astrophysics, who designed Aditya-L1’s key observation instrument, the Visible Emission Line Coronagraph (Velc), "can weigh up to trillions of kilograms and travel at astonishing speeds of 3,000 kilometers per second. Imagine a gigantic fireball hurtling towards us from the Sun!" Remarkably, these enormous fireballs can cover the 150-million-kilometer distance between the Earth and the Sun in just 15 hours.
Aditya- L1’s cameras captured images beginning at 13:08 GMT on July 16, 2023, showcasing its ability to track these elusive events in unprecedented detail. Luckily, the CME observed on this date traveled a different direction and posed no threat to Earth.
The ability to predict and monitor CMEs is crucial because these powerful solar eruptions can have a significant impact on Earth.
“Solar storms, solar flares, and regular coronal ejections can disrupt Earth’s weather as well as space weather where nearly 7,800 satellites are stationed,” explains Dr. Ramesh. While these events rarely pose a direct threat to humans, they can cause significant havoc by disrupting Earth’s magnetic field. Imagine the Northern Lights becoming a global spectacle, as they did during the strongest solar storm on record, the Carrington Event of 1859.
This historic event knocked out telegraph lines worldwide. Today, the potential for disruption is even greater, with our reliance on satellite communications, power grids, and other electronic systems.
What makes Aditya-L1 unique is its unique vantage point. "Our instrument is so large that it can simulate the position of the Moon, giving Aditya- L1 an uninterrupted view of the corona 24 hours a day and 365 days a year," says Dr. Ramesh.
Unlike NASA and ESA spacecraft, which are larger and therefore sometimes have their view of CMEs obscured, Velc can confidently predict the precise moment these eruptions begin and their trajectory.
With these remarkable capabilities, Aditya-L1 is poised to revolutionize our understanding of the Sun and its influence on Earth. As we become more reliant on technology, the insights gleaned from this mission will be invaluable in protecting our planet from the Sun’s powerful outbursts.
