| M43 is part of the much larger Orion Nebula complex. This section features
a an extremely bright OB star that is creating a matter bound Stromgren sphere.
This means that the star is ionizing the gas that is near it- making a
sphere of glowing (pink) hydrogen gas. The size of this sphere is determined
by the density of gas/dust that surrounds the star. Another good example
of this process can be found in
M43 and the Orion Nebula are around 1,500 light years away. Many new
stars will be formed from these clouds of gas.
