An anonymous reader quotes a report from New Scientist: NASA has announced plans to extend operations of the famous space telescope for another five years, through to June 2021. That means it will still be on the job when its successor, the James Webb Space Telescope (JWST) launches in 2018, giving astronomers a dual view of the universe. "Hubble is expected to continue to provide valuable data into the 2020s, securing its place in history as an outstanding general-purpose observatory in areas ranging from our solar system to the distant universe," said a NASA statement. Squeezing more life out of Hubble means it will overlap with NASA's next big telescope, JWST when it launches in 2018. While Hubble sees the cosmos in visible and ultraviolet light, JWST operates in the infrared. The various wavelengths can reveal different aspects of stars and galaxies, so using the scopes in tandem will enable astronomers to study the heavens in even greater detail.
