Jennifer Wiseman, Hubble Senior Project Scientist at NASA’s Goddard Space Flight Center in Maryland says, “One of the main reasons for building Hubble was to be able to measure more precisely the expansion rate of the universe.”
The Hubble Space Telescope was launched 30 years ago. Since then, it has been changing how we look at the universe. Hubble uses visible, ultraviolet, and near-infrared light to capture views of the stars, and the distant universe. The special clarity in the images captured by Hubble is simply because of its positioning above the Earth’s atmosphere.
The space observatory was made in a joint effort between NASA and the European space agency. The telescope is named after Edwin Hubble, the pioneering astronomer who found out that the distant clouds in space are galaxies.
