December 2017 Call for Proposals

Gemini North and South are accepting proposals for the Fast Turnaround (FT) program. Here, we give information specific to this proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program. FT-specific proposal templates must now be used for all FT proposals; see the "PIT information" section below. The revised 2018A PIT must be used

About The Gemini Observatory

Exploring The Universe, Sharing its Wonders


The Gemini Observatory consists of twin 8.1-meter diameter optical/infrared telescopes located on two of the best observing sites on the planet.

2018A Call for Proposals Announced

Gemini is now accepting proposals for observing time in Semester 2018A. The submission deadline varies with participant. A new version of the Phase I Tool (PIT) has been released to support proposal submissions.

The Little Star That Survived a Supernova

The progenitor of LP40-365 could be a binary star system like the one shown in this animation. Here, an ultra-massive and compact dead star called a white dwarf (shown as a small white star) is accreting matter from its giant companion (the larger red star).

Gemini Confirms a New Class of Variable Stars

Gemini South spectra for three BLAPs. Best fits of stellar atmosphere models are shown with red lines. Effective temperatures, surface gravities, and helium abundances derived for these stars are similar to the values obtained from spectra for the prototype object previously studied. This shows that all the newly discovered variables form a homogeneous class of objects. Credit: Gemini Observatory/AURA/NSF
