FREDERICTON — A total solar eclipse is a rare celestial event that always generates excitement, but next month's version is expected to be unusually spectacular.
"So you have got lots of spikes and activity coming up in different places, and it's hard to really predict exactly where they will be," Bryans said."But if you're looking at the eclipse, you wouldn't see a nice, smooth corona. You'll see, oh, jagged hedgehog in fear." These prominences occur because the sun's magnetic activity is uneven across its surface. There are areas where the magnetic field is extremely high, causing eruptions so powerful that they can be felt on Earth in the form of interference in satellite communication or cellphone signals, Bryans said.
Bryans explained that the magnetic activity causes an ejection of plasma — the ionized gas that makes up the sun — from the sun's surface. The plasma is then looped back down, pulled by gravity.
