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.
The Gemini South 8-meter telescope gets a new coating of silver, increasing the sensitivity of the mid-infrared instruments on the telescope.
Using Nod & Shuffle mode on GMOS-N, ultra-deep spectra of several hundred distant, elusive galaxies were captured, which helps to paint a new picture of the nature and evolution of galaxies some 7 - 10 billion years ago.
Gemini North Near Infrared Imager (NIRI) observations have confirmed that many of the "irregular" satellites around Jupiter and Saturn share a common ancestry.
Designed and built by the University of Durham (UK), the new GNIRS Integral Field Unit (IFU) arrived on Cerro Pachón (Gemini South) in February in a deceptively small package.
A team of Brazilian and French astronomers has discovered four surprisingly metal-rich HII regions and associated clusters of hot young stars in an otherwise empty region of intergalactic space near the galaxy group called Stephan's Quintet.
A timely discovery by American amateur astronomer Jay McNeil, followed immediately by observations at the Gemini Observatory, has provided a rare glimpse into the slow, yet violent birth of a star about 1,500 light-years away.
