NGC 6357 in Scorpius is also
known as the "War & Peace"
Nebula. Scientists of the
Midcourse Space Experiment
gave it that name because
they thought that in infared, the
western part of the nebula
resembled a dove, and the
eastern part a skull. Those
elements are not easily visible
in this wider field view (which
did not include infared
imaging.) Instead, this
rendition includes narrowband
data using filters that transmit
at the emission frequencies of
sulfur (red), hydrogen (green),
and oxygen (blue)...the
so-called Hubble palette.
