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.
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.
The 200th paper is titled “The luminosity function of the fossil group RX J1552.2+2013” by Claudia L. Mendes de Oliveira et al.
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.
With system and science verification complete, the Gemini Bench-mounted High-Resolution Spectrograph (bHROS) is available for science programs in 2006A.
A series of coordinated observations, made under ideal conditions by the world’s largest collection of big telescopes, delivered surprising new insights into the ancestry and life cycles of comets.
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust. The discovery might provide insights into our own solar system’s eventual demise several billion years from now.
The Gemini Observatory released a pair of images today that capture the dynamics of two very different interactions in space.
Astronomers using the 8-meter Gemini South telescope have revealed that the galaxy NGC 300 has a large, faint extended disk made of ancient stars, enlarging the known diameter of the galaxy by a factor of two or more.
