Gemini astronomers Inger Jørgensen and Kristin Chiboucas have shed new on galaxy evolution: the mass to light ratios of the galaxies indicate that low-mass galaxies have experienced more recent star formation than high-mass galaxies.
A new image released today reveals how Gemini Observatory's most advanced adaptive optics (AO) system will help astronomers study the universe with an unprecedented level of clarity and detail by removing distortions due to the Earth’s atmosphere
The Gemini Observatory Board of Directors opens 2013 with new leadership and a number of membership changes. The changes reflect regular term expirations as well as the departure of the United Kingdom from the partnership and subsequent adjustments to partner shares.
Potential asteroid collision in 2040 is a non-threat based on new Gemini Observatory data.
A recent milestone for the Gemini Observatory sees the observatory moving forward until the end of this decade with its strong international partnership intact.
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.
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.
