The Hubble Heritage Project was founded by a group of astronomers in 1998. The team releases on an almost monthly basis pictures of celestial objects like planets, stars, galaxies and galaxy clusters. A team of astronomers and image processing specialists selects images from the Hubble Space Telescope's public data archive, which are usually only shared within the astronomical community. Because most of the photos were taken for scientific reasons they often lack sufficient exposure across a range of colors. A small amount of observation time with the Hubble Space Telescope has been granted to the team to fill in the gaps in these images.
