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.
FLAMINGOS-2 is undergoing commissioning on the Gemini South telescope. We now invite the Gemini community to propose System Verification (SV) science programs for the imaging and long-slit spectroscopy modes
Results from the Gemini Cluster Astrophysics Spectroscopic Survey (GCLASS) reveal that galaxies at a redshift of about one have at least two reasons for the curtailment of star formation.
Gemini’s next-generation adaptive optics system produces highest-resolution with largest field-of-view ever captured from the ground using laser guide star technology.
To celebrate the publising of Gemini Observatory’s 1000th scientific paper, we highlight some of the top science results every week through the end of 2011.
A team of researchers made deep, multi-band observations of NGC 604, a giant star forming region in M33 using the Near-infrared Imager and Spectrometer on Gemini North.
Observations with the Gemini North telescope in Hawai‘i reveal evidence for what astronomers are calling the largest black holes ever measured in our nearby cosmological neighborhood.
Australian student Benjamin Reynolds was named winner of the 2011 Australian Gemini School Astronomy Contest for his proposed observations of the galaxy NGC 7552.
Gemini Observatory's 1000th paper, by Gemini astronomer Tom Geballe and the team, published in the November 2nd electronic edition of the journal Nature.
The staff of the Gemini Observatory wish to congratulate the winners of the 2011 Nobel Prize for Physics: Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess.
New observations with the Gemini Multi-Object Spectrograph on Gemini North confirm a new dwarf companion to the Andromeda Galaxy.
An international team of astronomers, using data from the Gemini North telescope, are revealing the history of the outer Solar System by measuring the mutual orbits of extremely widely separated binaries located beyond Neptune in the icy Kuiper Belt.
Thanks to a partnership between Gemini South and the Extension Department of the University of La Serena as well as participation by the Municipality of La Serena and the Tourism Board (SERNATUR), the Viaje al Universo and AstroDay Chile programs introduced our Chilean host communities to Gemini (and astronomy) in exciting new ways.
