Stars, Dust and Nebula in NGC 2170
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.
