The bright butterfly shaped region is a stellar nursery, with a string of bright, hot stars along its body. These massive stars are destined to explode as supernovae within the next 10 million years.
Strung out all along this region of the nebula are wispy filaments with protostars embedded within them.
The image was mapped using Herschel instruments PACS and SPIRE at wavelengths of 70, 160, and 250 microns, corresponding to the blue, green and red channels, respectively. North is to the right and east is up.
