C57 – Hubble-X

This Hubble image, taken with the Wide Field and Planetary Camera 2, shows another huge star-forming region in Caldwell 57, this one called Hubble-X. The image shows a bright cloud at the nebula’s core, which contains many thousands of newly formed stars (the brightest appear in this image as bright dots). For comparison, the smaller bright cloud just above it is about the same size and brightness as the Orion Nebula in our galaxy.
