"All-Clear" Asteroid Will Miss Earth in 2040

Potential asteroid collision in 2040 is a non-threat based on new Gemini Observatory data.

Looking Ahead: Gemini’s Partnership Beyond 2015

A recent milestone for the Gemini Observatory sees the observatory moving forward until the end of this decade with its strong international partnership intact.

“Green-bean Galaxies” and the Demise of Quasars

A team of astronomers has discovered a spectacular and very rare phenomenon in galaxies. It is interpreted as a light echo from an earlier, very active, quasar phase that has since shut down. Thus they appear green in some datasets giving them the colorful moniker “green-bean galaxies.”

Probing the Atmosphere of an Extrasolar Planet with Gemini South

A group of British astronomers, led by Neale P. Gibson of the University of Oxford, used the Gemini Multi-Object Spectrograph (GMOS) to probe the atmosphere of a transiting extrasolar planet identified as WASP-29b.

Gemini and Subaru Telescopes Expand International Collaboration

The new time exchange agreement between Gemini and Subaru makes the entire suite of instrumentation available at each observatory open to any astronomer in the countries of the U.S., Japan, Canada, Australia, Brazil, Argentina, and Chile.

Poetry in Motion: Rare Polar-Ring Galaxy Captured in New Image

This new Gemini Legacy image captured the colorful and dramatic tale of a life-and-death struggle between two galaxies interacting.

Sharpest-ever Ground-based Images of Pluto and Charon: Proves a Powerful Tool for Exoplanet Discoveries

Using a method called reconstructive speckle imaging, the researchers took the sharpest ground-based snapshots ever obtained of Pluto and Charon in visible light, which hint at the exoplanet verification power of Gemini telescopes when combined with speckle imaging techniques.

The Best Standard Candle for Cosmology

When observed at near-infrared wavelengths, type Ia supernovae provide the greatest precision as “standard candles” for measuring cosmological distances.

Viaje al Universo 2012

Gemini Observatory held their annual “Viaje al Universo” in 8/27-31. The week long program brought astronomy into the classroom, with a wide variety of educational talks and workshops throughout schools in the Elqui Valley, La Serena and Coquimbo.


A team, led by Edo Berger of Harvard University, made the most of a dying star’s fury to probe a distant galaxy some 9.5 billion light-years distant. The dying star is the most distant stellar explosion of its kind ever studied.

Gemini Observations Play Key Role in Testing Einstein’s Theories

A research used the Gemini North telescope to observe two white dwarf stars in a close gravitational embrace. The observations help confirm another ramification of Einstein’s General Theory of Relativity, which holds that the energy the pair loses in the shortened period is carried away in gravitational waves.

Astronomers Reassured by Record-breaking Star Formation in Huge Galaxy Cluster

The team, led by MIT's Michael McDonald, found evidence for extreme star formation, or a starburst, significantly more extensive than any seen before in the core of a giant galaxy cluster.

Markus Kissler-Patig Begins Tenure as Gemini Observatory's Director

Dr. Markus Kissler-Patig begins his tenure as the Gemini Observatory Director.

Petite AGNs Reveal New Secrets

High-resolution, mid-infrared observations at Gemini North and South have revealed a wide range of morphologies for low-luminosity active galactic nuclei (AGN).


TYC 8241 2652, a young analog of our Sun, transformed completely: from displaying all of the characteristics of hosting a solar system in the making only a few years ago to showing little of the warm dusty material thought to originate from collisions of rocky planets.

Celestial Tapestry is Born of Uncertain Parentage

A new Legacy Image from the Gemini Observatory reveals the remarkable complexity of the planetary nebula Sharpless 2-71 (Sh 2-71).

Gemini Helps Dissect an X-ray Surprise in M83

Gemini/HST follow-up data revealed a black hole with an unexpectedly low-mass, highly evolved giant companion, whose atmosphere is intermittently streaming material into an accretion disk feeding the black hole.


In mid-July 2012, astronomers from around the world will converge in San Francisco, California to discuss recent and future science from the Gemini Observatory.

Gemini Science Meeting 2012: Register Now to Have Your Say in Gemini’s Future…

The Gemini Science Meeting, a forum for users of the Gemini telescopes, is scheduled for July 17-20, 2012 in San Francisco California. 

Gemini Video Explains the Next Generation of Adaptive Optics

Learn how Gemini is leading the way in developing the next generation of adaptive optics to power the new Gemini Multi-Conjugate Adaptive Optics System (GeMS).
