The Gemini South 8-meter telescope gets a new coating of silver, increasing the sensitivity of the mid-infrared instruments on the telescope.
Using Nod & Shuffle mode on GMOS-N, ultra-deep spectra of several hundred distant, elusive galaxies were captured, which helps to paint a new picture of the nature and evolution of galaxies some 7 - 10 billion years ago.
Gemini North Near Infrared Imager (NIRI) observations have confirmed that many of the "irregular" satellites around Jupiter and Saturn share a common ancestry.
Designed and built by the University of Durham (UK), the new GNIRS Integral Field Unit (IFU) arrived on Cerro Pachón (Gemini South) in February in a deceptively small package.
A team of Brazilian and French astronomers has discovered four surprisingly metal-rich HII regions and associated clusters of hot young stars in an otherwise empty region of intergalactic space near the galaxy group called Stephan's Quintet.
A timely discovery by American amateur astronomer Jay McNeil, followed immediately by observations at the Gemini Observatory, has provided a rare glimpse into the slow, yet violent birth of a star about 1,500 light-years away.
The GLARE (Gemini Lyman Alpha at Reionisation Era) team, using Gemini to study the early universe, has just discovered a surprisingly large number (three) very high redshift galaxies ( z = 5.83, 5.79 and 5.94) in a same region of the southern GOODS field.
A Canadian/Gemini team used the ALTAIR adaptive optics system with the Near Infrared Imager (NIRI) on the Gemini North Telescope to probe the red stellar content in the starburst galaxy M-82.
Astronomers have obtained the most detailed observations ever of an old but otherwise normal massive star just before and after its life ended in a spectacular supernova explosion.
Verne Smith of the University of Texas El Paso led an international team of astronomers to a detailed study of the physical properties of the recently discovered nearby brown dwarf companion to Epsilon Indi,
The prototype of the Gemini Science Archive (GSAp) was recently released to the astronomical community and the general public.
The Gemini Deep Deep Survey (GDDS) determined the heavy element enrichment of the interstellar medium (ISM) in the redshift desert using a sub-sample of 13 galaxies with high star formation activity.
The Gabriela Mistral Medal for excellence in education has been awarded outside of Chile for the first time to Gemini Observatory in celebration of its outstanding efforts in international astronomy education through the StarTeachers exchange program.
The Gemini Observatory recently successful coated the secondary mirror on Gemini South with silver.
A team of astronomers used the visiting instrument FLAMINGOS, a multi-object near infrared spectrograph at Gemini South, to study the high redshift quasar SDSS J083643.85+005453.3 (SDSS J0836+0054).
An international team used GMOS-IFU on Gemini North to exploit the rich galaxy cluster A 2218. They used A 2218 as a magnifying glass to observe distant background galaxies at a comparable level of detail to galaxies at redshift z ~ 0.1.
PHOENIX was used to sample multiple stellar atmospheres and has revealed tantalizing clues that neutrino interaction during the supernovae explosion of massive stars is involved in the genesis of fluorine.
High spatial resolution NIRI images taken in the 1.69-micron methane absorption band expose the detailed structure and varying chemistry of the clouds high in the Jovian atmosphere.
As a part of commissioning and engineering runs at the Frederick C. Gillett Gemini North Telescope in June and July 2003, the mid-infrared imager and spectrograph MICHELLE was used to image the young planetary nebula NGC 7027.
