NGC
6334, also known as the Cat’s Paw Nebula, is a realm of extremes. The
nebula contains about 200,000 suns’ worth of material that is coalescing
to form new stars, some with up to 30 to 40 times as much mass as our
Sun. It houses tens of thousands of recently formed stars, more than
2,000 of which are extremely young and still trapped inside their dusty
cocoons. Most of these stars are forming in clusters where the stars are spaced up to a thousand times closer than the stars in the Sun’s neighborhood.
The cause of the baby boom in NGC 6334 isn’t clear. Two processes often suggested to trigger bursts of star formation are blast waves from a nearby supernova explosion, or molecular cloud collisions when galaxies smash together.
This representative-color photo of NGC 6334 combines infrared data from the Herschel and Spitzer spacecraft and ground-based NEWFIRM instrument. Warm dust, illuminated by the high-mass stars that are scattered throughout the cloud complex, shows up in green. The red and orange spots mark the very massive young stars that are just forming within the nebula. The dark clouds, primarily at the upper left and lower right of the image, mark the densest areas where the next generation of stars will form. The hazy blue-white regions mark where the light emitted by the hot young stars is reflected back to us by the remaining dust and gas. In this photo red shows light at a wavelength of 70 microns, green is 8 microns, and blue is 1.2 microns.
