The distinctive shape of the Ring Nebula, the glowing shroud around a dying Sun-like star, makes it a popular celestial object that appears in many astronomy books. New observations of the Ring Nebula by NASA's Hubble Space Telescope, however, reveal a new twist on an iconic nebula.

STScI solicits proposals for HST Observing, Archival & Theoretical Research. Full details are made available through two documents, the Call for Proposals and the HST Primer.
The Cycle 21 Call for Proposals and the Cycle 21 HST Primer.
Using Director's Discretionary observing time, Hubble will undertake a revolutionary three-year deep field observing program to peer deeper into the Universe than ever before. The Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. These will be the second deepest observations of blank fields and deepest observations of clusters and their lensed galaxies ever obtained. Opportunities to propose for Archival and Theory programs related to these observations were announced in the Cycle 21 Call for Proposals. There is also a separate proposal opportunity for the creation of lensing maps prior to Cycle 21.

The ETCs are web-based applications that assist Hubble users in preparing Phase I and Phase II observing proposals. The ETCs calculate exposure times or SNRs for simulated astronomical observations using any of HST's primary instruments:
