The Sun in ultraviolet light shows prominences,
sliding plasma and tiny spikes darting up just
above the Suns surface, seen best along its
edge

16
The erupting prominence seen in UV light
17
The Sun in just one wavelength of UV light
18
A 3D composite of the Sun in UV light the
brighter areas are active regions darker areas
are coronal holes

The Sun is mistic

• Consists of different layers (onion-like
  structure)
• hot core nuclear fusion
• radiative zone many photons
• convective zone - hot plasma rising
• atmosphere (photosphere, chromosphere, corona)
• The Suns peculiar rotation
• Magnetic seasons of the Sun
