This image shows the massive galaxy cluster MACS J0152.5-2852,
captured in detail by the NASA/ESA Hubble Space Telescope's Wide Field
Camera 3. Almost every object seen here is a galaxy, each containing
billions of stars. Galaxies are not usually randomly distributed in
space, but instead appear in concentrations of hundreds, held together
by their mutual gravity. Elliptical galaxies, like the yellow fuzzy
objects seen in the image, are most often found close to the centres of
galaxy clusters, while spirals, such as the bluish patches, are usually
found to be further out and more isolated.
A version of this image obtained tenth prize in the Hubble's Hidden Treasures image processing competition, entered by contestant Judy Schmidt.
