CROWNING MOMENT
During a total solar eclipse in 2017, the moon will block the sun, allowing people to see the solar corona (as seen in this picture from a 1999 eclipse).
In astronomy, a corona is the luminous plasma «atmosphere» of the Sun or other celestial body, extending millions of kilometres into space, most easily
seen during a total solar eclipse, but also observable in a coronagraph.
Instead, the sun stretches 0.5 ° across, so
even during total solar eclipses, some of its light passes either above or below the moon, creating a less - dense shadow called the penumbra.
«They are associated with the legs of solar prominences — these are beautiful concentrations of cool plasma in the very hot solar corona that can easily be seen as pink
structures during total solar eclipses,» adds Labrosse.
The vanishingly thin atmosphere of the sun — the wispy stuff that can be glimpsed
faintly during total solar eclipses — simmers at 1 million˚C, 200 times hotter than the «fire» beneath it.
That effect was first
demonstrated during a total solar eclipse in 1919, when the positions of stars near the Sun were observed to be slightly shifted from their usual positions — an effect due to the pull of the Sun's gravity as the stars» light passed close to the Sun.

seen during the total solar eclipse.»
