Hubble Space Telescope: Pictures, Facts & History
The Hubble Space Telescope Is Falling - Forbes
Over the last three decades the Hubble Space Telescope has played a crucial role in probing key parameters relevant to fundamental physics and cosmology. The H(0) key project figured prominently in during the early years, and subsequent programs have reduced measurement uncertainties to less than 3%. More recently, Hubble has investigated other parameters, including testing the nature of dark matter through observations of merging galaxy clusters and using white dwarf spectra to constrain the gravity dependence of the fine structure constant.
Looking forward, the STScI Director convened a working group drawn from the physics and cosmology communities to provide advice on how Hubble might contribute to future investigations in fundamental physics. The committee was chaired by Prof. Bhuvnesh Jain (University of Pennsylvania), and included Prof. Neal Dalal (University of Illinois), Professor Cora Dvorkin (Harvard University), Prof. Jeremy Heyl (University of British Columbia), Prof. Marc Kamionkowski (Johns Hopkins University), Dr. Phil Marshall (SLAC National Accelerator Laboratory), and Prof. David Weinberg (Ohio State University). The committee consulted with members of the community and submitted a final report in November 2017.

Today, Hubble continues to provide views of cosmic wonders never before seen and is at the forefront of many new discoveries.
Shortly after Hubble was deployed in 1990, the observatory's primary mirror was discovered to have a flaw that affected the clarity of the telescope's early images.
