The Hubble space telescope began its task 25 years ago, peering from orbit into the fathomless universe and gathering images of stars and galaxies so far off in space and time that some had formed when the universe itself was forever in formation
The Hubble images are spectacular, and in it’s huge collection it shows as a gallery of high-resolution photographic masterpieces for a very large-format volume. They will remain as an art gallery for collectors long after the Hubble itself falls back into Earth’s atmosphere and burns up like a meteor — 22 years from now, NASA estimates.
To astronomers, of course, the Hubble has provided far more than pictures, for each image reveals details of phenomena that have long puzzled astrophysicists on Earth: panoplies of new-forming stars, collisions of galaxies far distant from our own, and stellar explosions, or supernovae, that could harbor black holes in their hearts. There are even suggestions of the dark energy that still puzzles cosmologists.
