Using NICI on the Gemini-South telescope in Chile, an international team led by University of Hawai‘i astronomers have directly imaged a brown dwarf in a tight orbit around a young Sun-like star.
The first two accepted papers based on observations with NICI at Gemini South include discoveries of several previously unknown companions in binary star systems as well as the study of the age distributions of stars in the outer regions of the galaxy M83.
A planet only about eight times the mass of Jupiter has been confirmed orbiting a Sun-like star at over 300 times farther from the star than the Earth is from our Sun. The newly confirmed planet is the least massive planet known to orbit at such a great distance from its host star.
A Canadian-U.S. team's analysis, based on follow-up observations using the Gemini North telescope and the Multiple-Mirror Telescope (MMT), shows a clear signature of a tidally destroyed dwarf planet that once orbited the parent star.
Using NIRI on the Gemini North telescope, James De Buizer and William Vacca (SOFIA-USRA) obtained spectra that, for the first time, directly identify the origin of “green fuzzy” emission.
The starburst galaxy NGC 1313 is a stellar incubator delivering stars on a scale rarely seen in a single galaxy of its size. Now a striking new Gemini Observatory image reveals the multitudes of glowing gas clouds in this galaxy’s arms.
A newly discovered gravitational lens in a relatively nearby galaxy cluster is leading astronomers to conclude that the cluster hosts the most massive galaxy known in our local universe.
Gemini Observatory aims to be one of the most energy efficient astronomical facilities, with the highest standards of environmental protection.
The discovery of a very young planet-like object, paired with a low-mass brown dwarf. appears to have formed in about a million years–more rapidly than some theories of planet formation predict.
A striking new Gemini Observatory image of the Owl Nebula, a prominent object visible in the northern sky, was released today (March 25, 2010) as the culmination of a nationwide student essay contest in Canada.
Barry Rothberg and Jacqueline Fischer of the Naval Research Lab find that IR-luminous mergers appear younger and less massive in the near-IR but indistinguishable from old, massive ellipticals at optical wavelengths.
An international team provides insight into the consequences of galaxy-scale outflows using new observations with NIFS on Gemini North.
The staff of Gemini Observatory extends its deepest sympathies to the families of those who suffered losses or are displaced due to the major magnitude 8.8 earthquake that struck southern Chile early Saturday morning, February 27, 2010.
A dramatic new image from the Gemini North telescope illustrates the dynamic and sometimes violent process of star birth. It also demonstrates the capabilities of new filters available to researchers using the GMOS.
Observations at the Gemini Observatory provide convincing new evidence that stellar heavyweights may be born in much the same manner as lightweights like our Sun.
Using the Gemini South telescope in Chile, astronomers at UCLA have found dusty evidence for the formation of young, rocky planets around a star some 500 light years distant.
Gemini science highlights from the 215th American Astronomical Society Meeting in Washington DC.
Using adaptive optics to remove atmospheric blurring, Gemini Observatory released an image showing previously hidden forensic secrets at the ballistic core of the Homunculus Nebula.
Gemini encourages readers to access the publication electronically as part of Gemini's initiative to find new ways to operate "Greener."
>New results from Gemini NIFS observations show the early life of a distant galaxy, building its first generation of stars.
