A Canadian, U.S., and Australian team selected 24 individual white dwarfs in the field of the rich open star cluster NGC 2099 (M37), the largest spectroscopic sample ever obtained of white dwarfs in an individual star cluster.
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.
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.
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.
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 announced the six teachers selected for the 2005 StarTeachers exchange program between Hawaii and Chile.
Gemini staff have successfully repeated the coating of a 8-meter primary mirror with protected silver during a 9-day shutdown period in November.
A team of researchers used the newly commissioned GNIRS on Gemini South to determine the nature of the low-mass object OTS 44.
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.
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.
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.
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.
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.
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.
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.
Gemini and Keck have agreed to exchange five nights of observing time at each facility in semester 2005A. The Gemini user community will have access to five nights of HIRES on Keck I. In return, Keck users will have access to MICHELLE on Gemini North for five nights.
A team of U.S. astronomers reports the discovery of extremely high rates of star formation in one of the most distant known galaxies in the universe, LALA J142442.24+353400.2 Using GMOS-N.
Infrared observations of Supernova 1987A by T-ReCS on Gemini South revealed dust emissions at a wavelength of 10 microns.
The Gemini Deep Deep Survey (GDDS) was completed using the Gemini North telescope and the Gemini Multi-Object Spectrograph (GMOS-N). Spectra of several hundred distant galaxies were obtained and measured.
Using the entire battery of large telescopes on Mauna Kea, including GMOS-N, a University of Hawaii IfA team has obtained a unique data set of the X-ray cluster MACS J0717.5+3745 and its surroundings.
