Two upcoming papers based on optical and mid-infrared data from the Gemini North telescope focus on the dynamic core of the spiral galaxy NGC 1068.
Multi-Instrument Nights at Gemini North and South: a Powerful Approach to Observing
Web Feature | 2005 November 22
The instrument clusters located at the Cassegrain foci of the Gemini telescopes are perhaps the most unique collections of astronomical instrumentation ever assembled on ground-based telescopes.
Gemini's Nod-&-Shuffle Provides Critical Deep Spectroscopic Data for Supernova Legacy Survey
Web Feature | 2005 November 21
The unique nod-and-shuffle mode on the Gemini Multi-object Spectrograph (GMOS) provides a reduction of sky line residuals in the red part of the spectrum, making it a better tool to observe the faintest and highest redshift candidates.
Altair Undergoes Successful Performance Upgrade
Web Feature | 2005 October 28
The recent addition of a field lens in the Altair adaptive optics system has resulted in a significant improvement in near-infrared imaging capabilities at Gemini North.
Cracks or Cryovolcanoes? Surface Geology Creates Clouds on Titan as Observed by Gemini and Keck
Press Release | 2005 October 20
Geologic activity on the surface of Saturn's moon Titan is belching puffs of methane gas into the atmosphere of the moon, creating clouds.
Gemini Tracks Down Distance to Short Gamma-Ray Burst For The First Time
Web Feature | 2005 October 5
Astronomers using the Frederick C. Gillett Gemini Telescope on Mauna Kea have found the source of short flashes of gamma rays from outer space: a collision of two dead stars.

Mauna Kea Giants Find Common Nursery for Comets
Press Release | 2005 September 15
A series of coordinated observations, made under ideal conditions by the world’s largest collection of big telescopes, delivered surprising new insights into the ancestry and life cycles of comets.
Dusty Old Star Offers Window to Our Future, Astronomers Report
Press Release | 2005 September 8
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust. The discovery might provide insights into our own solar system’s eventual demise several billion years from now.
A Chinese Dragon and a Knotted Galactic Embrace
Press Release | 2005 August 26
The Gemini Observatory released a pair of images today that capture the dynamics of two very different interactions in space.
Gemini Uncovers 'Lost City' of Stars
Press Release | 2005 August 10
Astronomers using the 8-meter Gemini South telescope have revealed that the galaxy NGC 300 has a large, faint extended disk made of ancient stars, enlarging the known diameter of the galaxy by a factor of two or more.
Gemini Observatory Shows That "10th Planet" Has a Pluto-Like Surface
Press Release | 2005 July 29
Gemini Observatory has obtained a preliminary spectrum of 2003 UB313, the so-called "10th planet".
Dustiest Star Could Harbor a Young Earth
Press Release | 2005 July 20
A relatively young star located about 300 light-years away is greatly improving our understanding of the formation of Earth-like planets.
Gemini Prepares for Planet Searching with NICI
Web Feature | 2005 July 7
Gemini Observatory is actively looking for sub-stellar mass companions using the existing Adaptive Optics (AO) system Altair on Gemini North, and building the specialized near-infrared coronagraph (NICI) with its own AO system for Gemini South.
