wiki Word: Corona

Definition: The corona is a plasma atmosphere surrounding celestial bodies and stars like the sun.

Include any facts, details, examples, good LINCS words or phrases, questions, important info, etc. that might help students understand and remember this vocab word.

 The Sun's Corona is basicly an outer layer of super-hot plasma that can reach up to 2 million degrees. Its helium and hydrogen are super-heated so much that the atom are completely stripped of electorons. Years ago, scientisis couldn't even recognize the components of the corona. That's when they started proposing the idea of coronium. The corona emits massive amounts of X-rays radiation. solar wind and flares also originate there. How the corona still exists is a mystery to scientists. The SOHO and TRACE vehicles are currently gathering data on the sun. The corona is seen as a white rim around the moon during a solar eclipse. The shape of the corona is changing thanks to the sunspot cycle. Coronal Mass Ejection (or CME) is When the corona launches high-velocity flares going well over ome million miles per hour.

                        These are five pictures of the sun's corona- you can only see it during a solar eclipse. The one on the above right is a solar flare. The bottom right is how the sun looks using an x-ray lense.

SO WHAT??? SECTION: Why are we studying this term? Why do you need to understand this word to be sucessful in science? How does this term apply to any of our class labs or the real world?

 Thanks to our lovely corona, we get sunlight, sunburn, and skin cancer. Heat radiation from the corona warms our planet by sending out sunlight all around.
