- Hubble does not travel to stars, planets or galaxies. It takes pictures of
them as it whirls around Earth at 17,500 mph.
- NASA's Hubble Space Telescope has made more than 930,000 observations and
snapped more than 570,000 images of 30,000 celestial objects since its mission
began in 1990.
- Hubble has circled Earth more than 110,000 times.
- With those trips, Hubble has racked up plenty of frequent-flier miles, about
2.8 billion, which is Neptune's average distance from the sun.
- More than two decades of Hubble observations have produced more than 45
terabytes of data, enough information to fill nearly 5,800 DVDs.
- Each month the orbiting observatory generates more than 360 gigabytes of
data, which could fill the storage space of an average home computer.
- About 4,000 astronomers from all over the world have used the telescope to
probe the universe.
- Astronomers using Hubble data have published more than 8,700 scientific
papers, making it one of the most productive scientific instruments ever built.
In 2009 scientists published 648 journal articles on Hubble telescope
- Hubble weighs 24,500 pounds -- as much as two full-grown
- Hubble's primary mirror is 2.4 meters (7 feet, 10.5 inches) across -- taller
than retired NBA player Gheorghe Muresan, who is 2.3 meters (7 feet, 7 inches)
tall. Muresan is the tallest man ever to play in the NBA.
- Hubble is 13.3 meters (43.5 feet) long -- the length of a large school bus.
