Explanation:
The large majestic
Lagoon Nebula
is home for many young stars and hot gas.
Spanning 100 light years across while lying only about 5000 light years distant, the
Lagoon Nebulae is so big and bright that
it can be
seen without a
telescope toward the
constellation of
Sagittarius.
Many bright stars are visible from
NGC 6530, an
open cluster that
formed in the nebula only several million years ago.
The greater nebula, also known as
M8 and NGC 6523,
is named "Lagoon" for the band of dust seen to the
left of the open cluster's center.
A bright knot of gas and dust in the nebula's center is known as the
Hourglass Nebula.
The above picture is a digitally sharpened
composite of exposures taken in specific colors of light emitted by
sulfur (red),
hydrogen (green), and
oxygen (blue).
Star formation continues in the
Lagoon Nebula as witnessed by the many
globules that exist there.
