India's Sun Mission Finds New Clues About Solar Mystery
Listen to the story
An Indian space mission that studies the Sun has produced new findings. These findings could help explain some old mysteries about our closest star.
One of the biggest questions is about the corona, the Sun's outer atmosphere. Strangely, the corona is millions of degrees hotter than the Sun's surface below it.
Scientists have long wondered why this happens. They also want to know how the corona keeps such an extremely high temperature for so long.
This is one of the most puzzling problems in solar science. Normally, temperature drops as you move away from a heat source, but the Sun behaves differently.
The Indian mission has been collecting data to help answer these questions. Its new findings give scientists fresh information to study.
Although the exact answer is still not fully known, this research is seen as an important step forward. It adds new evidence to a long-running scientific puzzle.
Studying the Sun matters because its activity can affect Earth. Solar events can influence satellites, power systems and communication on our planet.
Missions like this one help scientists build a clearer picture of how the Sun works. Over time, such research may finally solve one of astronomy's enduring mysteries.
