Scientists Study Total Solar Eclipse to Unravel Sun's Corona Mystery
On Wednesday, August 12, the Moon moved between the Earth and the Sun and covered the Sun's bright face for a little while.
This special event is called a total solar eclipse, and millions of people looked up to see it.
Scientists used the short period of darkness to study the Sun's corona, its extremely hot outer atmosphere.
The corona is usually hidden by the Sun's bright glare, but the Moon blocked that light.
Scientists are puzzled because the corona is about one million degrees Celsius, even hotter than the Sun's visible surface.
They want to learn how the Sun's magnetic energy heats it so much.
A NASA team flew a special plane to get a longer and clearer view of the corona.
The Sun sometimes sends bursts of charged particles toward Earth that can create geomagnetic storms.
These storms can disturb satellites, communications, and power grids.
By studying the eclipse, scientists hope to predict such space weather better in the future.
A total solar eclipse occurred on August 12, 2026, crossing the Northern Hemisphere from Greenland and Iceland to Spain and part of Portugal.
The brief period of totality revealed the Sun's corona, which can reach around 1 million degrees Celsius.
A NASA-funded team flew a WB-57 aircraft at about 50,000 feet through the eclipse's shadow to observe the corona with four cameras.
Scientists hope the observations will explain how the Sun's magnetic energy heats the corona and releases charged particles into space.
Better understanding of the corona could improve forecasts of geomagnetic storms that can disrupt satellites, communications, and power grids.
- Who
- Scientists, including a NASA-funded team flying a WB-57 aircraft, along with millions of sky-watchers who witnessed the eclipse.
- What
- A total solar eclipse revealed the Sun's corona, giving researchers a rare chance to study its million-degree outer atmosphere, solar eruptions, and space weather.
- When
