Known to the public as Old Tippecanoe, the former general of the Indian campaigns delivered an hour-and-forty-five-minute speech in a snowstorm.
The Corona. The outermost layer of the Sun is called the corona or the crown. The corona is very thin and faint and is therefore very difficult to observe from the earth.Typically, we observe the corona during a total solar eclipse or by using a coronagraph telescope which simulates an eclipse by covering the bright solar disk.he Corona. The outermost layer of the Sun is called the corona or the crown. The corona is very thin and faint and is therefore very difficult to observe from the earth.
The innermost layer, the troposphere, contains most of the planet's weather and extends out to 10â15km above the surface. The next layer out, the stratosphere, is drier and less dense and extends out to about 50km. The Sun's UV light breaks down oxygen in the stratosphere to form the Earth's protective ozone layer. The mesosphere, thermosphere, and ionosphere make up the remaining outer layers that extend out to about 100km.
