solar corona
Eclipse reveals it
The solar corona is the outermost layer of the sun's atmosphere, visible as a halo of plasma during a total eclipse.
It extends millions of kilometers into space and is paradoxically hotter than the sun's surface—a phenomenon still not fully explained.
Scientists study the solar corona to understand solar winds and their effects on Earth.
