Answer 1:
All though the sun appears to be yellow in colour to the bare eyes, there are multiple
layer which have different wavelengths which are beyond the range of visibility. NASA has
developed the most powerful Solar Observatory which is capable of identifying every details of
the ever changing sun. The white light is capable of detecting the Coronal mass ejection when
the disc of the sun is studied in the coronagraph. The devices that are used for viewing the sun
includes, the Reuven Ramaty High Energy Solar Spectroscope Imager, and the Interface Region
Imaging Spectrograph (Lodders 2019).
There are 3 layers of sun, they are the Core, Radiation Zone and the Convection Zone.
The suns’ atmosphere is known and the photosphere, beyond this the chromosphere and lastly it
is the Crown, which is Corona.
Features of each atmospheric layer of sun:
 Photosphere:
 This is the closest layer to the sun and is around 500 km thick.
 The solar energy is released as the light energy in this layer which
illuminates the planets around.
 The surface of this layer is marker by the granules of plasma, which are
bright in color and cold dark sunspots which is due to the magnetic field of
the sun.
 The solar flares are sourced here as well, which can extend up to miles.
These are made of X rays and UV radiation, electromagnetic radiation and
radio-waves.
