The eruption of V1647 Orionis resulted in the appearance of a reflection nebula called “McNeil’s Nebula,” named after the amateur astronomer, Jay McNeil, who discovered the object. By early 2006 the star and its environment were very similar to their pre-burst stage.
The Gemini South Multi-Object Spectograph (GMOS) recently captured a dramatic image of a vast cloud complex named DEM L316 located in the Large Magellanic Cloud.
This page highlights a sample of Gemini related science results presented at the 211th meeting of the American Astronomical Society meeting in Austin Texas from January 7-11, 2008.
Over 75 staff and family participated (or led) the family summit tours to see the Gemini North and South telescope facilities first-hand and see where family members work
On December 3-4, 2007, more than 70 engineers, technicians, safety officers and coordinators, administrative personnel and astronomers from observatories around the world met in La Serena, Chile for the first Chile Observatory Earthquake Preparedness Workshop.
Simultaneous observations made by four of the most powerful Earth- and space-based telescopes revealed an unusually active magnetic field on the ultracool low-mass star TVLM513-46546.
Astronomers have found evidence for the formation of young rocky planets around the star HD 23514 located in the well-known Pleiades (Seven Sisters) star cluster that is easily visible in the current evening sky.
A team studied the dynamical properties of CG 6, a massive compact group at a redshift z=0.22, that has several properties in common with known fossil groups. The study is based on multicolor imaging and deep spectroscopic observations obtained with GMOS at Gemini South.
Observations that combine data from the ground-based Gemini North telescope and NASA’s orbiting Chandra X-ray observatory have led to the discovery of the most massive known stellar black hole.
A Canada-US-UK team has released the first results from the Gemini Deep Planet Survey (GDPS), a near-infrared adaptive optics search for giant planets and brown dwarfs around 85 nearby young stars.
The GMOS South spectra were taken in the nod-and-shuffle mode, necessary to measure the weak residual flux at wavelengths shorter than the Lyman emission line in order to determine the absorption by neutral hydrogen.
An international team of researchers has shown that quasar pairs may be excellent beacons for finding clusters of galaxies in the early universe.
By observing the comet Tempel 1 pre-, and post-impact, the Harker team gathered baseline data sets with MICHELLE on Gemini North to compare with data obtained during the moments surrounding impact.
A team used the adaptive optics fed integral-field spectrograph NIFS on Gemini North to explore the inner structure of the jet in the young star HL Tau, located about 460 light years away in the constellation of Taurus.
Deep Gemini imaging of the cluster of galaxies Hydra I at a distance of 176 million light-years has revealed an abundance of massive luminous metal-rich globular clusters that appears to impersonate ultra-compact dwarf galaxies.
The six distant quasars a team observed are at redshifts ranging between z = 5.8 to 6.3 and correspond to a period when the universe was only about one billion years old. Using GNIRS at Gemini South and NIRI at Gemini North, the team found these very young quasars to be already super-enriched in heavy elements.
NIRI observations with AO showed evidence of frigid geysers spewing material up through cracks in the crust of Pluto's companion Charon and recoating parts of its surface in ice crystals.
