This STS-125 crew patch shows Hubble. The overall structure and composition of the universe is shown in blue and filled with planets, stars and galaxies. The black background is indicative of the mysteries of dark-energy and dark-matter. The red border of the patch represents the red-shifted glow of the early universe. Soaring by the telescope is the shuttle that initially deployed Hubble and has enabled astronauts to continually upgrade the telescope, significantly contributing to the expansion of human knowledge.
