Hubble Paints Picture of the Evolving Universe
Astronomers have just assembled one of the most comprehensive portraits yet of the universe?s evolutionary history, based on a broad spectrum of observations by the Hubble Space Telescope and other space and ground-based telescopes. In particular, Hubble?s ultraviolet vision opens a new window on the evolving universe, tracking the birth of stars over the last 11 billion years back to the cosmos? busiest star-forming period, about 3 billion years after the big bang. This photo encompasses a sea of approximately 15,000 galaxies ? 12,000 of which are star-forming ? widely distributed in time and space.

NASA and The Space Telescope Science Institute (STScI) are pleased to announce the Cycle 26 Call for Proposals for Hubble Space Telescope (HST) Observations and funding for Archival Research and Theoretical Research programs.
Participation in this program is open to all categories of organizations, both domestic and foreign, including educational institutions, profit and nonprofit organizations, NASA Centers, and other Government agencies.
Cycle 26 will extend from October 1, 2018 to September 30, 2019. We will accept proposals for the following instruments: ACS, COS, FGS, STIS, and WFC3.
This solicitation for proposals will be open through August 17, 2018 8:00pm EDT. The Astronomer's Proposal Tools (APT), which is required for Phase I Proposal Submission will be released for Cycle 26 Phase I use on May 14, 2018.
Results of the selection will be announced by the end of October 2018
Please see the Cycle 26 Announcement page for detailed information.
Please take note of the What's New for Cycle 26 section on the announcement page.
In particular, the Director has decided to implement an anonymous review process for Cycle 26.
This follows recommendations by a working group and
discussion with the Space Telescope Users Committee (presentation).The decision has been endorsed by the STUC,
the Space Telescope Institute Council and the AURA Board, and is supported by NASA. A description of the process and instructions on how to adjust proposals to comply with the new requirements are included in the
Call for Proposals.

Fundamental Physics with HST
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.
