In its 13 years of surveying the heavens, NASA's Hubble Space Telescope has made about 553,000 exposures and probed nearly 19,000 celestial targets.
Hubble has whirled around Earth nearly 80,000 times, racking up 2 billion miles. That's like making 11 round trips to the Sun.
Each day the telescope generates enough data - more than 15 gigabytes - to fill 25 CD-ROMS.
The orbiting observatory's observations have amounted to more than 13 terabytes of data.
Hubble's digital archive delivers nearly 60 gigabytes of data a day to astronomers all over the world. That information would fill 100 CD-ROMS.
Astronomers have published 4,000 scientific papers on Hubble results.
