Launched in 1990, NASA's Hubble Space Telescope has made over 1 million observations of more than 36,000 celestial objects.
In its 23-year lifetime the telescope has made nearly 126,000 trips around our planet. Hubble has racked up plenty of frequent-flier miles, more than 3 billion, which is roughly Neptune's average distance from the Sun.
One terabyte of Hubble data is added to the archive every month.
Astronomers using Hubble data have published more than 11,000 scientific papers, making it one of the most productive scientific instruments ever built.
