The Sun
Morgan Conville
Core
The innermost part of the sun. This is where nuclear fusion occurs, which gives the earth energy.
Radiative Zone
This is where energy created in the core is moved outwards through radiation.
Convective Zone
The outermost layer of the solar interior. It is cool enough for heavier elements to exist, which can make the area unstable, which causes the visible granules on the sun.
Photosphere
The Sun’s visible surface, granular patterns we see are on this layer, and look small in pictures, but are estimated to be about the size of the Moon. This is the layer where we see sun spots.
Chromospere
The chromosphere is an irregular layer above the photosphere.Temperature is about 20,000°C, which causes hydrogen to emit light that gives off a reddish color. This is where solar flares are visible.
Corona
The Corona is the Sun's outer atmosphere.It looks like a pearly white crown surrounding the Sun, but can only be seen during total eclipses of the Sun . It it so hot, that most elements are stripped down to their nuclei.
sunspots
Sunspots are dark regions around the size of planets that appear on the surface of the Sun. Sunspots are dark because they are colder than the areas around them. They are cause by welling up of the sun's magnetic field to the photosphere.
prominence
An arc of gas that erupts from the surface of the Sun are held above the Sun's surface by strong magnetic fields. They can last for many months and most will erupt, spewing solar material into space.
flare
Flares are bright outbursts of energy that happen as the Sun’s magnetic fields twist, tear and reconnect.
Aurora
These can be caused when Coronal Mass ejections from the sun collide with the earth's magnetic field causing a geomagnetic storm. This resulted in the release of photons of light causing auroras.
