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.”
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.
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.
This new Gemini Legacy image captured the colorful and dramatic tale of a life-and-death struggle between two galaxies interacting.
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.
When observed at near-infrared wavelengths, type Ia supernovae provide the greatest precision as “standard candles” for measuring cosmological distances.
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.
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.
Dr. Markus Kissler-Patig begins his tenure as the Gemini Observatory Director.
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.
A new Legacy Image from the Gemini Observatory reveals the remarkable complexity of the planetary nebula Sharpless 2-71 (Sh 2-71).
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.
The Gemini Science Meeting, a forum for users of the Gemini telescopes, is scheduled for July 17-20, 2012 in San Francisco California.
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).
Dr. William Smith, President of the Association of Universities for Research in Astronomy Inc. (AURA), announced today the selection of Dr. Markus Kissler-Patig as the new Director of the Gemini Observatory.
Astronomers using the Gemini South telescope have discovered the first clear-cut example of a windy helium and nitrogen rich central star of a planetary nebula.
The Hawai‘i Journey program, currently in its eighth year, engages the local community at all levels and has become Gemini North’s flagship local outreach program.
Ongoing observations made with Gemini of an extremely red pair of such Kuiper Belt objects (KBOs) in an orbiting binary system offer an indirect glimpse into the past. Astronomers obtained nearly monthly observations of the pair, named 2007 TY430, to yield precise measurements of their orbital motion.
