A rosebud by any other name: NASA's Wide-field Infrared Survey Explorer, or WISE, snapped what NASA called a cosmic rosebud blossoming with new stars. The stars, called the Berkeley 59 cluster at just a few million years old, are young on stellar time scales. The rosebud-like red glow surrounding the hot, young stars is warm dust heated by the stars. Green "leafy" nebulosity enfolds the cluster, showing the edges of the dense, dusty cloud. This green material is from heated polycyclic aromatic hydrocarbons, molecules that can be found on Earth in barbecue pits, exhaust pipes and other places where combustion has occurred, NASA stated.
