Gemini Sheds New Light on Dark Matter in NGC 3379

Using Gemini observations of globular clusters in NGC 3379 (M105), a team has found evidence for normal quantities of dark matter in the galaxy’s dark halo.

Gemini South Traces the Flow of Gas into the Grasp of the Black Hole in NGC 1097

An international team recently mapped the gas velocity field and structure within the circumnuclear ring of the SBb LINER/Seyfert 1 galaxy NGC 1097 in unprecedented detail.

The 200th Gemini Paper

The 200th paper is titled “The luminosity function of the fossil group RX J1552.2+2013” by Claudia L. Mendes de Oliveira et al.

Gemini Looks Down the Mouth of an Interstellar Cavern

Known as the N44 superbubble complex, a storm of billowing clouds blown by the winds from massive stars, and set aglow by their light, is the focus of a striking image released today by Gemini Observatory.

Fossil group of galaxies shows dearth of low luminosity members

Astronomers used GMOS on the Gemini North Telescope to determine the first luminosity function (LF) of the galaxies in fossil group RX J1552.2+2013 based on spectroscopy of the member galaxies. 

Gemini North probes the gas, dust and stars at the center of the active galaxy NGC 1068

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

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

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

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

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

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.

bHROS Available on Gemini South for Semester 2006A

With system and science verification complete, the Gemini Bench-mounted High-Resolution Spectrograph (bHROS) is available for science programs in 2006A.

Mauna Kea Giants Find Common Nursery for Comets

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

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

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

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

Gemini Observatory has obtained a preliminary spectrum of 2003 UB313, the so-called "10th planet". 

Dustiest Star Could Harbor a Young Earth

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

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.
