A picture paints a thousand stars

How good is this picture:


The image is a mosaic, taken from 39 separate frames with more than 11 hours of exposure time using the Swift satellite’s Ultraviolet/Optical Telescope telescope. It is the most detailed ultraviolet image of an entire galaxy ever taken. And indeed, the high resolution shows clear gas clouds and star-forming regions, even in the crowded heart of the galaxy.
