Dusting for Clues: Gemini Discovers Evidence for Colliding Bodies in Planet Forming Disk

Astronomers using T-ReCS have observed new details in the dusty disk surrounding the nearby star Beta Pictoris which show that a large collision between planetary-sized bodies may have occurred there as recently as the past few decades.

Stunning Images Herald Opening of Gemini Observatory's Image Gallery

A pair of beautiful images (NGC 1532/NGC1531 and NGC 2467) released today in San Diego at the 205th meeting of the American Astronomical Society marks the formal debut of the Gemini Observatory’s Image Gallery.

Gemini Observatory Welcomes 2005 with Release of Galactic Fireworks Image

In the image, the face-on spiral galaxy NGC 6946 is ablaze with colorful galactic fireworks fueled by the births and deaths of multitudes of brilliant, massive stars.

New Clouds Add to Titan's Mystery

A U.S. team has discovered a new phenomenon in the atmosphere of Saturn’s largest moon Titan. The new images reveal atmospheric disturbances at Titan’s temperate mid latitudes—about halfway between the equator and the poles. 

Gemini Observatory Announces Selection of 2005 StarTeachers

Gemini Observatory announced the six teachers selected for the 2005 StarTeachers exchange program between Hawaii and Chile.

Gemini North 8-meter Primary Mirror Successfully Coated with Silver on Mauna Kea

Gemini staff have successfully repeated the coating of a 8-meter primary mirror with protected silver during a 9-day shutdown period in November.

Strong spectral signatures of steam betray low mass brown dwarf using GNIRS at Gemini South

A team of researchers used the newly commissioned GNIRS on Gemini South to determine the nature of the low-mass object OTS 44.

Gemini Observes Remains of Massive Star Cluster Near Milky Way's Galactic Center

A team of astronomers has confirmed the physical association of a cluster of massive stars in the infrared source IRS 13 near the center of the Milky Way galaxy using Hokupa'a/QUIRC.

Gemini Detects Something "Cool" in Our Neighborhood: Closest Known Brown Dwarf has a Companion

Epsilon Indi Ba is the closest confirmed brown dwarf to our solar system. Astronomers using PHOEBIX on Gemini South telescope made a related but unexpected detection of its companion, Epsilon Indi Bb.

Deep near infrared Gemini observations with NIRI refute alleged redshift z = 10 galaxy

An international team used the Gemini North Near Infrared Imager (NIRI) to obtain even deeper H-band images of the field of the possible z=10 galaxy.

Galactic Contortionists Captured by Gemini

Stephan's Quintet image released today captures the graceful interactions of a galactic ballet, on a stage some 300 million light years away, that might better be described as a contortionist's dance. 

Why do Galaxies in the Young Universe Appear so Mature?

Gemini Deep Deep Survey (GDDS) revealed that the galaxies appear to be more fully formed and mature than expected at the early stage in the evolution of the Universe. 

Mystery Object Neither Star Nor Brown Dwarf

Astronomers using the Gemini North and Keck II telescopes have peered inside a violent binary star system to find that one of the interacting stars has lost so much mass to its partner that it has regressed to a strange, inert body resembling no known star type.

The Gemini Science Archive: the Data are Yours!

After more than five years of planning and development, the Gemini Science Archive Version 1 (GSA V.1.0) was released on September 20, 2004.
