Scientists use NASA data to predict solar corona before eclipse
Our sun, like many stars, is adorned with a crown. It’s called a corona (Latin for “crown” or “wreath”) and consists of long, thread-like strands of plasma billowing out from the sun’s surface. The powerful magnetic field of the sun defines these strands, causing them to ripple and evolve their structures constantly. The strands are faint, however, so the only way to observe the corona with the naked eye is during a total solar eclipse.
