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.
Another supernova (SN 2011dh) has exploded in the Whirlpool Galaxy (M51), and now astronomers have identified its unusual progenitor using data from Gemini NIRI.
The image of Kronberger 61, discovered by Austrian amateur astronomer Matthias Kronberger, is featured at an International Astronomical Union symposium on planetary nebulae this week in Spain’s Canary Islands. The research team’s work features a striking image of the new nebula obtained with the Gemini Observatory.
An international team of astronomers discovered the most distant known supermassive black hole, seen as a luminous quasar caused by gas falling into the black hole.
In early April 2011, after more than a decade of effort, the Gemini Multi-Conjugate Adaptive Optics System (GeMS) saw starlight for the first time.
An international team of astronomers using the Gemini North telescope revealed that a powerful outburst of radiation originated from a massive black hole at the center of a distant galaxy.
