Massive Old Star Reveals Secrets On Deathbed

Astronomers have obtained the most detailed observations ever of an old but otherwise normal massive star just before and after its life ended in a spectacular supernova explosion.

Gemini South/PHOENIX Strikes Again

Verne Smith of the University of Texas El Paso led an international team of astronomers to a detailed study of the physical properties of the recently discovered nearby brown dwarf companion to Epsilon Indi,

The Gemini Science Archive Prototype: Released !!

The prototype of the Gemini Science Archive (GSAp) was recently released to the astronomical community and the general public.

Gemini's First Look at the Interstellar Medium in the "Redshift Desert"

The Gemini Deep Deep Survey (GDDS) determined the heavy element enrichment of the interstellar medium (ISM) in the redshift desert using a sub-sample of 13 galaxies with high star formation activity.

Chilean StarTeachers Bring The Universe Into Hawai`i Classrooms

The Gabriela Mistral Medal for excellence in education has been awarded outside of Chile for the first time to Gemini Observatory in celebration of its outstanding efforts in international astronomy education through the StarTeachers exchange program.

Gemini South's Secondary Mirror Sports Shiny Silver Coat

The Gemini Observatory recently successful coated the secondary mirror on Gemini South with silver. 

Gemini South + FLAMINGOS Find Distant Quasar SDSS J0836+0054 to be Surprisingly Red and Dusty

A team of astronomers used the visiting instrument FLAMINGOS, a multi-object near infrared spectrograph at Gemini South, to study the high redshift quasar SDSS J083643.85+005453.3 (SDSS J0836+0054).

Galaxies Under the Cosmic Microscope: a GMOS-North Study of the Lensed Galaxy #289 in A 2218

An international team used GMOS-IFU on Gemini North to exploit the rich galaxy cluster A 2218.  They used A 2218 as a magnifying glass to observe distant background galaxies at a comparable level of detail to galaxies at redshift z ~ 0.1. 

PHOENIX on Gemini South Reveals Clues about the Origin of Fluorine

PHOENIX was used to sample multiple stellar atmospheres and has revealed tantalizing clues that neutrino interaction during the supernovae explosion of massive stars is involved in the genesis of fluorine. 

Near-Infrared Images Reveal Structure in Jupiter's Cloudy Atmosphere

High spatial resolution NIRI images taken in the 1.69-micron methane absorption band expose the detailed structure and varying chemistry of the clouds high in the Jovian atmosphere.

MICHELLE Peers at the Dust and Gas of the Planetary Nebula NGC 7027

As a part of commissioning and engineering runs at the Frederick C. Gillett Gemini North Telescope in June and July 2003, the mid-infrared imager and spectrograph MICHELLE was used to image the young planetary nebula NGC 7027.

Looking Sharp: Images from New Gemini Spectrograph Rival View from Space

Among the images and spectra acquired during recent commissioning of the Gemini Multi-Object Spectrograph (GMOS) on the Gemini South Telescope, one image is particularly compelling - the Hickson Compact Group 87 (HCG87).

Gemini South Mid-Infrared Imager T-ReCS Glimpses Dry Ice Frost on Mars

T-ReCS on Gemini South was used to obtain an image of Mars using a spectral filter centered at a wavelength of 12.8 microns. The image was made on 2003 June 4.

New Gemini Images Exemplify the Power of Adaptive Optics

A razor-sharp image was released today revealing new details at the heart of a famous star cluster M-13, taken with adaptive optics system Altair on Gemini North.

OSCIR Probes Heated Dust in the Active Galactic Nucleus of the Spiral Galaxy NGC 4151

Astronomers used the mid-infrared camera OSCIR mounted on Gemini North to observe the nuclear region of NGC 4151 at the wavelengths of 10.8 and 18.2 microns.

NIRI Catches the Infrared Glow of a Major Neutron Star Outburst

Gemini's Near-Infrared Imager, NIRI, was trained on the magnetar 1E 2259+586 shortly after X-ray bursts were detected in June of 2002. 

Gemini South Tracks Optical Microflares Around Black Hole in Binary System

Astronomers have embarked on a study of aperiodic optical variability of SXTs, using the Acquisition Camera on the Gemini South telescope, in order to explore the source of the microflares on short timescales.

Gemini North and Keck Probe Saturn's Moon Titan from Clouds to Icy Highlands

Henry Roe and collaborators used adaptive optics to study Titan's clouds and the observations have revealed that the southern hemisphere shows more cloud activity than the northern hemisphere.
