Observing databases offline Dec 2

The Gemini observing databases will be offline for several hours on Wednesday December 2 while we perform quarterly software updates.

During this time the following services will be unavailable:

  • Observing Tool synchronizations, file transfers, and non-sidereal target queries
  • CADC program key validation
  • Phase I Tool guide star probability queries

Astronomers Spy a Nursery of Baby Exoplanets

Figure 1. Image of HD 100546 obtained with the Gemini Planet Imager at near-infrared wavelengths (1.6 microns). The cross shows the position of the star, the green hatched lines show the region interior to which GPI's coronagraph blocks our view of the system. HD 100546 b appears as a bright point source sitting on a finger of disk emission.

Gemini Featured at Extreme Solar Systems III Conference

Observations using the Gemini Planet Imager are featured prominently at the Extreme Solar Systems III meeting ongoing this week (Nov. 29 - December 4) in Waikoloa Hawai‘i. Below are two results from a press conference on December 1, 2015.

Cancelation of the November GeMS run

The GeMS / GSAOI laser run that was planned to take place this week had to be canceled. Unfortunately the laser and the Canopus Real Time Control system were not operational and in spite of intense efforts to resolve these problems in time for the laser window there was just not sufficient time to get the system in an operational state. We will continue to work towards ensuring that the upcoming January GeMS / GSAOI run will be a success.

Gemini Characterizes Cheshire Cat

Gemini spectroscopy provided critical spectroscopic data for characterizing the foreground lensing cluster and understanding its history and likely fate as a "fossil group."

Gemini Instrument Feasibility Study (GIFS) reports available.

Gemini Observatory is pleased to announce the release of the public GIFS reports.

OCTOCAM Feasibility Study


The OCTOCAM study was led by Antonio de Ugarte Postigo and managed by Pete Roming and Christina Thöne. The project was coordinated from the Instituto de Astrofisica de Andalucia (IAA-CSIC), with main collaborators at the Southwest Research Institute, Fractal SLNE, and George Washington University. The study began in April 2015 and concluded in October 2015.
