NGC 6357: The Lobster Nebula
Explanation: Why is the Lobster Nebula forming some of the most massive stars known?
No one is yet sure. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster
Pismis 24 near its center -- a home to unusually bright and
massive stars. The overall red glow near the inner star forming region results from the
emission of
ionized hydrogen gas. The surrounding nebula,
featured here, holds a
complex tapestry of gas,
dark dust, stars still forming, and newly born
stars. The intricate patterns are caused by
complex interactions between
interstellar winds,
radiation pressures,
magnetic fields, and
gravity. The image was taken with
DOE's
Dark Energy Camera on the 4-meter
Blanco Telescope at the
Cerro Tololo Inter-American Observatory in
Chile. NGC 6357 spans about 400 light years and lies about 8,000
light years away toward the constellation of the
Scorpion.
