A team of researchers have recently identified one of the best gravitational wave sources currently known using the Gemini Multi-Object Spectrograph on the Gemini North telescope and the Blue Channel spectrograph on the 6.5-meter MMT Telescope.
Observations using the Gemini Multi-Object Spectrograph on Gemini South reveal that galaxy-wide high-velocity outflows are extremely common among galaxies that host luminous quasars. These outflows may represent a crucial stage in a galaxy’s evolution when the supermassive black hole at its center begins injecting vast amounts of mass and energy into the galaxy.
An international team of astronomers has revealed a complicated outflow structure in the binary UY Aur (Aurigae). The team observed the binary using the Gemini North's NIFS (Near-Infrared Integral Field Spectrometer) with the Altair adaptive optics system and found that the primary star has a wide, open outflow, while the secondary star has a well-collimated jet.
A Lawrence Livermore team and international collaborators have tracked the orbit of a planet at least four times the size of Jupiter by using the Gemini Planet Imager which snapped an amazingly clear and bright image of the gas giant Beta Pictoris b after an exposure of just one minute.
An international team led by Université de Montréal researchers has discovered and photographed a new planet 155 light years from our solar system by combining observations from the Gemini Observatory, the Observatoire Mont-Mégantic (OMM), the Canada-France-Hawaii Telescope (CFHT) and the W.M. Keck Observatory.
The first Earth-sized exoplanet orbiting within the habitable zone of another star has been confirmed by observations with both the W. M. Keck Observatory and the Gemini Observatory.
Using the Altair adaptive optics (AO) system with the Gemini North telescope on Mauna Kea in Hawai’i to compensate for distortions to starlight caused by the Earth’s atmosphere, two NOAO astronomers were able to observe the shell of escaping material around Sakurai’s Object (V4334 Sgr).
New research by Stephen Kane (San Francisco State University) and collaborators shows that planets on highly eccentric (very non-circular) orbits are not necessarily explained by the presence of an additional star still present in the system. The Differential Speckle Survey Instrument (DSSI) on the Gemini North telescope was used in this research.
Gemini North completed dome shutter system repairs and is back on-sky.
Gemini Planet Imager (GPI) was designed, built, and optimized for imaging faint planets next to bright stars and probing their atmospheres. It will also be a powerful tool for studying dusty, planet-forming disks around young stars. It is the most advanced such instrument to be deployed on the 8-meter Gemini South telescope in Chile.
Gemini observations support an unexpected discovery in the galaxy Messier 101. A relatively small black hole (20-30 times the mass of our Sun) can sustain a hugely voracious appetite while consuming material in an efficient and tidy manner – something previously thought impossible.
Gemini's powerful new instrument for studying planets beyond the Solar System, the Gemini Planet Imager (GPI), has successfully received its first starlight for engineering and testing on the night of November 11-12.
Gemini’s flagship local outreach program in Chile, Viaje al Universo, blasted off early last week when Gemini South’s Nancy Levenson addressed nearly 800 students at Colegio San Joaquin.
Observations using the Gemini Near-Infrared Imager (GNIRS) at the Gemini North telescope have confirmed one of the lowest mass free-floating planet known, perhaps the very lowest.
The Gemini Planet Imager (GPI) is fully assembled in the Gemini South instrument lab and begins tesing and integration.
The first refereed science paper based on data from the Gemini Multi-conjugate adaptive optics System (GeMS) demonstrates the effective use of young, lower mass stars to determine the age of a star cluster.
“Celestial Pollution” from meteors like this weekend’s Perseid Meteor Shower sprinkle sodium high up in our atmosphere and give astronomers what they need to see the universe in much greater detail.
Gemini Observatory’s latest instrument, a powerful infrared camera and spectrograph called FLAMINGOS-2 at Gemini South, reveals its potential in a series of striking on-sky commissioning images released today.
Gemini observatory’s rapid-response allows for the detailed study of light from one of the most distant cases of a gamma-ray burst (GRB 130606A) illuminating a galaxy ever observed.
