corona

Coronal Mass Ejections are huge bursts of charged plasma travelling at millions of miles an hour that explode out of the Sun's outer atmosphere or corona.

Researchers have made a major leap in solar physics by finding the first direct evidence of small-scale torsional Alfvén waves within the Sun's corona.

Unlike the water that falls from clouds on Earth, solar rain takes place in the Sun's corona, the outermost layer made of intensely hot plasma.

It even has a name: The Second Immortal Dinner, in which Blundy for the first time read his corona, a poem composed as a sequence of sonnets, that had been lost long ago.

The heightened chance of a UK sighting has been caused by a fast-moving coronal mass ejection, which is a "release of plasma and magnetic field from the Sun's corona", late on Saturday night.
