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.
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.
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.
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).
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.
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.
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.
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.
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.
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.
In late February/early March, staff members completely moved into the new Gemini South Southern Base Facility in La Serena, Chile.
The Gemini Near-infrared Imager (NIRI) has been working reliably and delivering excellent images at wavelengths between 1 and 5 microns.
The tightest orbiting brown dwarf companion ever seen has been discovered orbiting the low mass star LHS 2397a, using adaptive optics on Gemini North.
The three Big Island StarTeachers selected are Kristen Luning of Keaau High School; Alicia Hui of Haili Christian School; and Christine Copes of Waiakea Elementary School. The three Chilean teachers are Carmen Luz Briones, Viviana Calderon and Jenny Opazo.
Violent bush fires ravaging Canberra destroyed most of the facilities at the Stromlo Observatory including Gemini's Near-Infrared Integral Field Spectrograph.
Gemini South Assistant Astronomer Dr. Michael Ledlow has helped confirm the existence of a giant, subatomic particle jet streaming from a spiral galaxy similar to the Milky Way.
Gemini South took delivery of GMOS-S in November 2002 and the facility mid-infrared imager and spectrometer Michelle arrived at Gemini North in the first week of December.
Using PHOENIX on Gemini South, an international team has determined the chemistry in 12 red giant stars spanning masses between 1-4 Msun.
Gemini Observatory honored Dr. Fred Gillett, a pioneer in infrared astronomy, by naming the Gemini North Telescope in his honor at ceremonies at the telescope on Mauna Kea, Hawai'i, November 13, 2002.
