Astronomers using the Gemini North telescope and W.M. Keck Observatory on Hawaii’s Mauna Kea have obtained the first-ever direct images identifying a multi-planet system around a normal star.

Planetary First Family Images

Gemini Observatory discovery images of a planetary system using the Altair adaptive optics system on the Gemini North telescope with the Near-Infrared Imager (NIRI)

A Highly-split Kuiper Belt Pair

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.

Infrared echoes from new and old dust - the case of SN 2006jc

 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).

First Picture of Likely Planet around Sun-like Star

Astronomers have unveiled what is likely the first picture of a planet around a normal star similar to the Sun using Gemini North telescope.

Probing a New Type of Stellar Explosion

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.

Young Asteroid Families Newly Classified by GMOS

Optical spectroscopy from the Gemini telescopes has revealed a relatively uncommon type of asteroid in the main-belt for the first time.

Gemini North Mirror Receives New Silver Coating During Major Shutdown

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.

A Rotating Compact Nuclear Stellar Cluster in NGC 4244

 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.

The 500th Referred Gemini Paper

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 Last Supernova Legacy Survey Spectrum

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.

Probing the host galaxy of a luminous quasar

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.

Twin Galaxies in a Gravitational Embrace

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.

Catching the Light of a Baby Supernova

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

Gemini Observatory Captures Image of Galaxy With "Baby Supernova" SN 2008D

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.

Does Methane Rain Down on Titan?

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.

Sampling Star-formation in Local LIRGs

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.

Two Very Young Massive Stars Unshrouded with LGS AO

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

Ammonia Found in Atmosphere of Coolest Brown Dwarf

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

Spectacular Star Cluster May Host Black Hole Missing Link

The well-known naked-eye star cluster Omega Centauri may be home to an elusive intermediate-mass black hole. Observations made using Gemini Observatory and Hubble Space Telescope provide convincing evidence that such black holes do exist and could even lead to an understanding of how they might evolve into larger supermassive black holes.
