The Corona: The Sun’s Fiery Halo

The corona is the Sun’s outer atmosphere, stretching millions of miles into space.
It’s hotter than the Sun’s surface, reaching temperatures of several million degrees.
The corona becomes visible to the naked eye during a total solar eclipse.
Its ghostly glow is shaped by the Sun’s magnetic fields.
The solar wind, a constant stream of charged particles, flows outward from the corona.
Coronal holes are regions where solar wind escapes more rapidly into space.
The corona’s extreme heat is still a mystery, defying normal energy transfer rules.
Powerful coronal mass ejections originate here, hurling plasma across the solar system.
NASA’s Parker Solar Probe is studying the corona up close for the first time.
The corona influences space weather, affecting satellites, astronauts, and power grids on Earth.
