NettetLike all large telescopes, Hubble uses a curved mirror to focus starlight. This mirror is located deep inside the telescope, protected by its long tube-like structure. As there is no atmosphere around Hubble, there is no risk of dust or corrosion reaching inside. Top NettetThis estimate is called the Hubble Constant, and scientists have been fine-tuning it ever since. The Hubble Space Telescope was launched in 1990, one of its major goals being to pin down the Hubble Constant. In 2001, a team studying supernovae with Hubble, along with ground-based optical telescopes, established a rate of 72 ± 8 km/sec/Mpc.
