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.
A team of astronomers have detected streaming gas flows toward the Seyfert nucleus of NGC 4051 located at an estimated distance of about 9.3 Megaparsecs.
The binary star SDSS J121209.31+013627.7, commonly known as SDSS 1212, is possibly the first interacting binary where a substellar companion has been directly detected -- with GNIRS on Gemini South.
From the last week of January, the weather atop Mauna Kea has been mostly snow and ice that we have been on the sky only once for a total of 2.3 hours since Jan. 28.
The eruption of V1647 Orionis resulted in the appearance of a reflection nebula called “McNeil’s Nebula,” named after the amateur astronomer, Jay McNeil, who discovered the object. By early 2006 the star and its environment were very similar to their pre-burst stage.
The Gemini South Multi-Object Spectograph (GMOS) recently captured a dramatic image of a vast cloud complex named DEM L316 located in the Large Magellanic Cloud.
