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.
Gemini Observatory has obtained a preliminary spectrum of 2003 UB313, the so-called "10th planet".
A relatively young star located about 300 light-years away is greatly improving our understanding of the formation of Earth-like planets.
Gemini Observatory is actively looking for sub-stellar mass companions using the existing Adaptive Optics (AO) system Altair on Gemini North, and building the specialized near-infrared coronagraph (NICI) with its own AO system for Gemini South.
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."
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 Deep Deep Survey (GDDS) revealed that the galaxies appear to be more fully formed and mature than expected at the early stage in the evolution of the Universe.
Astronomers using the Gemini North and Keck II telescopes have peered inside a violent binary star system to find that one of the interacting stars has lost so much mass to its partner that it has regressed to a strange, inert body resembling no known star type.
The Gemini South 8-meter telescope gets a new coating of silver, increasing the sensitivity of the mid-infrared instruments on the telescope.
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.
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.
Among the images and spectra acquired during recent commissioning of the Gemini Multi-Object Spectrograph (GMOS) on the Gemini South Telescope, one image is particularly compelling - the Hickson Compact Group 87 (HCG87).
