Explanation:
When stars form, pandemonium reigns.
A textbook
case is the star forming region
NGC 2170.
Visible above
are red glowing
emission nebulas of
hydrogen, blue
reflection nebulas of
dust, dark
absorption nebulas of dust, and the stars that formed from them.
The first massive stars formed from the dense gas will emit
energetic light and
winds
that erode, fragment, and
sculpt their birthplace.
And then they
explode.
The resulting morass is often as
beautiful as it is complex.
After tens of millions of years, the dust boils away,
the gas gets swept away, and all that is left is a naked
open cluster of stars.
