The Gemini North telescope on Mauna Kea successfully captured the dramatic fireworks display produced by the collision of NASA's Deep Impact probe with Comet 9P/Tempel 1.
Imaging by Gemini North's Michelle mid-infrared imager/spectrograph has allowed an international team of researchers to isolate and characterize the dusty remains of the supernova remnant SN 2002hh.
Gemini South Flamingos-I observations of the outer Trapezium region by Lucas et al. have probed the region to very faint levels in the infrared.
Using T-ReCS on Gemini South, David Ciardi and his collaborators have found that processing of dust grains around the proto-binary star Serpens SVS20 began at a surprisingly early point in the system’s evolution.
Recently a Canadian amateur astronomy group took advantage of a rare opportunity and used the Gemini 8-meter telescope to look more deeply into the remains of a particular stellar nursery than anyone ever has.
An Laser Guide Star is produced by a relatively low power laser beam that shines up from a telescope into a layer of sodium gas in our upper atmosphere, creating a temporary artificial "star."
A joint Chile-United Kingdom team has used the NOAO-built Phoenix near-infrared spectrometer on Gemini South to obtain high-resolution spectra (R~75,000) of the [Al VI] 3.66-micron line region in the planetary nebula NGC 6302 (the Bug Nebula).
Recent spectroscopic studies of infrared light reflected from the surface of Sedna reveal that it is probably unlike Pluto and Charon since Sedna's surface does not display evidence for a large amount of either water or methane ice.
Can galaxies observed at very high redshifts (at a time when the universe was a fraction of its current age) evolve to look like today's nearby galaxies simply by growing older? The answer is no.
The combination of Gemini sensitivity and Phoenix spectral resolution has allowed a team to observe a set of objects toward several GHII regions and search for kinematic clues to the circumstellar geometry of newly forming massive stars.
Using the IFU on GMOS-South, an international research team explores a spheroidal galaxy that captured a small gas-rich galaxy in a merger that led to a burst of star formation.
A Canadian, U.S., and Australian team selected 24 individual white dwarfs in the field of the rich open star cluster NGC 2099 (M37), the largest spectroscopic sample ever obtained of white dwarfs in an individual star cluster.
Astronomers using T-ReCS have observed new details in the dusty disk surrounding the nearby star Beta Pictoris which show that a large collision between planetary-sized bodies may have occurred there as recently as the past few decades.
A pair of beautiful images (NGC 1532/NGC1531 and NGC 2467) released today in San Diego at the 205th meeting of the American Astronomical Society marks the formal debut of the Gemini Observatory’s Image Gallery.
In the image, the face-on spiral galaxy NGC 6946 is ablaze with colorful galactic fireworks fueled by the births and deaths of multitudes of brilliant, massive stars.
A U.S. team has discovered a new phenomenon in the atmosphere of Saturn’s largest moon Titan. The new images reveal atmospheric disturbances at Titan’s temperate mid latitudes—about halfway between the equator and the poles.
Gemini Observatory announced the six teachers selected for the 2005 StarTeachers exchange program between Hawaii and Chile.
Gemini staff have successfully repeated the coating of a 8-meter primary mirror with protected silver during a 9-day shutdown period in November.
A team of researchers used the newly commissioned GNIRS on Gemini South to determine the nature of the low-mass object OTS 44.
A team of astronomers has confirmed the physical association of a cluster of massive stars in the infrared source IRS 13 near the center of the Milky Way galaxy using Hokupa'a/QUIRC.
