GS3 SCIENCE AND TECH:
India’s Aditya-L1 mission achieved a historic breakthrough on February 22, 2025, when its Solar Ultraviolet Imaging Telescope (SUIT) captured the first-ever image of a solar flare ‘kernel’ in the lower solar atmosphere. This discovery enhances our understanding of solar activity and its impact on Earth’s space environment.
Significance of the Discovery
- The flare ‘kernel’ was detected in the lower layers of the Sun’s atmosphere.
- The near-ultraviolet (NUV) wavelength used for observation is rarely utilized, offering new insights into solar activity.
- This discovery helps scientists understand how mass and energy move within the solar atmosphere.
About Aditya-L1 Mission
- India’s first solar observatory mission, launched on September 2, 2023.
- Studies the Sun from 1.5 million km away at Lagrange Point 1 (L1).
- Reached L1 on January 6, 2024.
- ISRO’s second space observatory mission, after AstroSat.
Scientific Payloads
- Features multiple instruments, with SUIT as the primary payload.
- SUIT captures images in the Near Ultraviolet (NUV) wavelength to study solar flares and atmospheric dynamics.
Solar Flare Observations
- On February 22, 2025, Aditya-L1 observed an X6.3-class solar flare, a high-intensity solar eruption.
- Provided data on temperature variations in the solar corona.
- Confirmed the relationship between flare energy and temperature changes, refining existing models.
Implications for Space Weather
- Solar flares and coronal mass ejections (CMEs) can disrupt satellites, power grids, and communication systems on Earth.
- Aditya-L1’s observations will aid in predicting and mitigating the effects of space weather disturbances.
Advancements in Solar Physics
- Enhances understanding of the Sun’s magnetic fields and plasma dynamics.
- Supports research into fusion energy, as the Sun acts as a natural fusion reactor.
