Using Open-Loop Adaptive Optics to Measure Black Hole Masses

An international team has used the adaptive optics facility ALTAIR with NIFS on the Gemini North Telescope to measure black hole masses in two normal galaxies

Exploring M82's Inner Wind and Disk

The well-known starburst galaxy M82 is a popular target for telescopes of all sizes, and now an international team used GMOS on the Gemini North telescope to help understand the complex dynamics of its galactic wind.

Australian Student’s Image Revealed

Australian high school student Daniel Tran won the Australian Gemini Partner Office imaging contest with the image of NGC 6751.

FLAMINGOS-2 Achieves First Light Milestone

As part of on-going acceptance testing, FLAMINGOS-2 (Florida Multi-object Infrared Grism Observing Spectrograph) obtained first light images on the Gemini South telescope.

Gemini Reaches Out to Easter Island (Rapa Nui)

We found ourselves in the Mataveri airport, the most isolated in the world, in the middle of the Pacific Ocean, 3,700 kilometers from continental Chile and nearly equally distant from Gemini North and Gemini South telescopes.


While far from a tropical rain forest, the equatorial region of Saturn's largest moon, Titan, has recently displayed tantalizing evidence that the parched, dry, ultra-frigid desert can support large-scale storms.


Looking almost 11 billion years into the past, astronomers have measured the motions of stars for the first time in a very distant galaxy.

Surprise Collision on Jupiter Captured by Gemini Telescope

Jupiter is sporting a glowing bruise after getting unexpectedly whacked by a small solar system object, according to astronomers using the Gemini North telescope on Mauna Kea in Hawai`i

Orderly Star Cluster Formation in Chaotic Galaxy Merger

An international team of astronomers used GMOS on the Gemini North telescope to observe 16 massive star clusters in the nearest pair of merging galaxies,

Adaptive Optics Reveals Strange Dynamics in Ultra-Compact Star-forming Region

Using the Altair adaptive optics system with NIFS on Gemini North, a US/Australian team have obtained unprecedented high-spatial resolution integral field spectra of the Ultra-Compact H II Region K3-50A.

Gemini User Survey 2008

Gemini conducted its first user survey at the end of 2008. Principal Investigators (PIs) for all programs from semesters 2006A – 2007B were asked a series of questions as users of one, or both, Gemini telescopes.

Dating young star clusters in starburst galaxy M82

The astronomers assembled key data for the largest sample of young extragalactic star clusters to date.

Ultra-deep GNIRS Spectrum Explores Stellar "Birth Control" in Early Universe

Using GNIRS, astronomers have obtained an ultra-deep near-infrared spectrum of a massive compact quiescent galaxy at a redshift of about 2.2. 

First Gemini/Subaru Science Meeting Sets Future Directions

About 200 users and staff of the Gemini and Subaru observatories and the National Gemini Offices participated in the first joint Gemini and Subaru science conference from May 18-22, 2009 at Kyoto University, Japan.

The 18 weeks of Winter on Mauna Kea – 2008-2009

The long-term weather loss for Gemini North for the 18 northern hemisphere “winter” weeks December 24, 2008 through April 28 is about 35%.

Gemini Observatory Releases Image of Most Distant Known Object in Universe

The Gemini Observatory has released the first color image of what astronomers are calling the most distant object ever seen in the universe: a Gamma-ray burst (GRB).

A Cool Dwarf in Aquarius

An international team has discovered a brown dwarf that will likely set the record as the coolest body ever detected outside our solar system.

No Lithium-6 in Exoplanet Host Stars

The observations by bench High-Resolution Optical Spectrograph (bHROS) on Gemini South have established that there is no detectable amount of Lithium-6 in five stars that host extrasolar planets.

Around the World in 80 Telescopes

On the nights of April 2-3 (3-4 UT) both Gemini telescopes participated in the “Around the World in 80 Telescopes” live, around the world control room webcast.
