Explanation:
The center of the Lagoon Nebula is a
whirlwind
of spectacular star formation.
Visible near the image center, at least two long funnel-shaped clouds,
each roughly half a
light-year long, have been formed by extreme
stellar winds
and intense energetic starlight.
The tremendously bright nearby star,
Herschel 36,
lights the area.
Walls of
dust hide and
redden
other hot young stars.
As energy from these stars pours into the
cool dust and gas,
large temperature differences in
adjoining regions can be created generating
shearing winds which may cause the
funnels.
This picture, spanning about 5 light years, combines
images taken by the
orbiting Hubble Space Telescope.
The
Lagoon Nebula, also known as
M8, lies about 5,000
light
years distant toward the
constellation of
Sagittarius.
