A group of astronomers using a battery of 8-meter telescopes, including Gemini North and South, have discovered a small pair of gravitationally bound Kuiper Belt objects with an enormous separation.
An international team observed the supernova and followed its evolution between days 86-493 after the explosion with an array of telescopes including the Gemini North telescope (using the Near Infrared Imager NIRI).
Astronomers have unveiled what is likely the first picture of a planet around a normal star similar to the Sun using Gemini North telescope.
The research shows that the famous nebulosity around the star Eta Carinae contains extremely fast-moving filaments of material that had not been seen before, and are not explained by current theories.
Optical spectroscopy from the Gemini telescopes has revealed a relatively uncommon type of asteroid in the main-belt for the first time.
Gemini North telescope facility on Mauna Kea underwent a major 20-day scheduled shutdown, during which the 8-meter primary mirror received new silver coating.
Anil C. Seth and collaborators demonstrate that the massive nuclear stellar cluster at the core of the spiral galaxy NGC 4244 is strongly rotating based on NIFS plus AO observations at Gemini North.
In mid June 2008, the 500th refereed Gemini paper was accepted for publication in The Astrophysical Journal, one of the main refereed astronomical journals.
The Supernova Legacy Survey (SNLS) had ambitious goals from the start - to produce a definitive sample of distant supernovae for cosmology. The 5-year survey began in 2003 and the final supernova spectrum was recently taken at Gemini North.
A team has made the first bulge stellar velocity dispersion measurement of a luminous quasar host with the Gemini North Laser Guide Star adaptive optics system.
Astronomers at Gemini Observatory have imaged two nearly identical spiral galaxies in Virgo, 90 million light years distant, in the early stages of a gentle gravitational embrace.
In a rapid follow-up observations of a mysterious X-ray flash in the galaxy NGC 2770 the Gemini North telescope was able to obtain a set of optical spectra that contains the earliest spectrum of a massive star ending its life in a supernova explosion outside of our galaxy's neighborhood
NGC 2770 has been captured by the Gemini Observatory in a spectacular new image that shows at least three recent supernovae locations including SN 2008D.
A team of astronomers has used infrared spectral images of Saturn's moon, Titan, acquired with the Gemini North Telescope, to dispute an earlier claimed detection of widespread morning methane drizzle.
Using T-ReCS on Gemini South, an international team led by Tanio Diaz-Santos (CSIC, Spain) has completed a survey of nearby Luminous Infrared Galaxies (LIRGs) at 8-microns.
An international team employed the Gemini North Laser Guide Star (LGS) adaptive optics system Altair to probe deep into the core of star forming region W51

Observations taken at Gemini North have detected ammonia in the spectra of the coolest brown dwarf. This is the first time such a finding has been made in near-infrared spectra of a sub-stellar object other than a planet
Using the powerful nod-and-shuffle technique from the Gemini Multi-Object Spectrograph at Gemini South, a research team led by Armin Rest (CTIO) have successfully obtained spectra from supernova light bouncing off interstellar dust.
Now in its second year, AstroDay Chile attracted an estimated 7,000 visitors to the local Mall Plaza La Serena and Gemini was joined by essentially all of the local astronomical institutions in central and northern Chile.
