Infrared Image Of The Berkeley 59 Cluster Taken By WISE

The young stars in the Berkeley 59 star cluster are the blue dots right of center. The dense dust cloud from which they formed glows red where it is being compressed and heated by the newly formed stars, and possibly giving birth to an even younger second generation of stars. The green marks the edges of the nebula. The opening in the nebula was caused by a massive star going nova, blowing a hole in the cloud leaving behind this flowering remnant.
