Using the Gemini South telescope in Chile, Australian astronomers have found a predicted "companion" star left behind when its partner exploded as a very unusual supernova.
New observations using T-ReCS on Gemini South reveal that in at least one case the mid-infrared emission from a young stellar source is associated with a spectacular outflow.
Nathan Smith (University of Colorado) used the high-resolution infrared spectrograph PHOENIX on the Gemini South telescope to observe the bipolar nebula surrounding Eta Carinae, revealing a very well-defined shell structure expanding ballistically at about 500 kilometers per second.
A new Gemini Observatory image of NGC 246, nicknamed the "Skull Nebula," shows what can happen as the outer atmosphere of a fast-moving, dying star lpushes through the complex soufflé of gas and dust that lies between the stars of our galaxy.
Astronomers from the University of Hawaii's Institute for Astronomy used Gemini North to make "crucial" observations of an object designated as Asteroid 118401. The observations showed that the body is ejecting dust like a comet,
A U.S.-led team of astronomers, led by Keivan Stassun of Vanderbilt University, has used Gemini South's PHOENIX to uncover the dynamics of the eclipsing brown dwarf pair 2MASS J0532184-0546085.
Mid-infrared astronomy is in full swing at Gemini with MICHELLE at Gemini North and T-ReCS at Gemini South.
A new era in astronomy education and outreach was ushered in with the opening of the ‘Imiloa Astronomy Center of Hawai‘i in Hilo, Hawai‘i.
Using Gemini observations of globular clusters in NGC 3379 (M105), a team has found evidence for normal quantities of dark matter in the galaxy’s dark halo.
An international team recently mapped the gas velocity field and structure within the circumnuclear ring of the SBb LINER/Seyfert 1 galaxy NGC 1097 in unprecedented detail.
The 200th paper is titled “The luminosity function of the fossil group RX J1552.2+2013” by Claudia L. Mendes de Oliveira et al.
Known as the N44 superbubble complex, a storm of billowing clouds blown by the winds from massive stars, and set aglow by their light, is the focus of a striking image released today by Gemini Observatory.
Astronomers used GMOS on the Gemini North Telescope to determine the first luminosity function (LF) of the galaxies in fossil group RX J1552.2+2013 based on spectroscopy of the member galaxies.
Two upcoming papers based on optical and mid-infrared data from the Gemini North telescope focus on the dynamic core of the spiral galaxy NGC 1068.
The instrument clusters located at the Cassegrain foci of the Gemini telescopes are perhaps the most unique collections of astronomical instrumentation ever assembled on ground-based telescopes.
The unique nod-and-shuffle mode on the Gemini Multi-object Spectrograph (GMOS) provides a reduction of sky line residuals in the red part of the spectrum, making it a better tool to observe the faintest and highest redshift candidates.
The recent addition of a field lens in the Altair adaptive optics system has resulted in a significant improvement in near-infrared imaging capabilities at Gemini North.
Geologic activity on the surface of Saturn's moon Titan is belching puffs of methane gas into the atmosphere of the moon, creating clouds.
Astronomers using the Frederick C. Gillett Gemini Telescope on Mauna Kea have found the source of short flashes of gamma rays from outer space: a collision of two dead stars.
