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