Recently, scientists have discovered a new phenomenon called “coreshine”. A core is a cold, dark nebula. “Coreshine” is when light from nearby stars reflects off the cores which reveals its age.
A cosmic “dragon” seems to soar among the stars. In visible light (upper half), the dragon is hidden by dust and gas as if it is “frolicking in the autumn mist”. The dragon is visible in infrared (lower half) though. This creature is actually forming stars rapidly and is known as M17 SWex. This photo was taken by Spitzer and managed by JPL.
