Australian student Benjamin Reynolds was named winner of the 2011 Australian Gemini School Astronomy Contest for his proposed observations of the galaxy NGC 7552.
Gemini Observatory's 1000th paper, by Gemini astronomer Tom Geballe and the team, published in the November 2nd electronic edition of the journal Nature.
The staff of the Gemini Observatory wish to congratulate the winners of the 2011 Nobel Prize for Physics: Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess.
New observations with the Gemini Multi-Object Spectrograph on Gemini North confirm a new dwarf companion to the Andromeda Galaxy.
An international team of astronomers, using data from the Gemini North telescope, are revealing the history of the outer Solar System by measuring the mutual orbits of extremely widely separated binaries located beyond Neptune in the icy Kuiper Belt.
Thanks to a partnership between Gemini South and the Extension Department of the University of La Serena as well as participation by the Municipality of La Serena and the Tourism Board (SERNATUR), the Viaje al Universo and AstroDay Chile programs introduced our Chilean host communities to Gemini (and astronomy) in exciting new ways.
Another supernova (SN 2011dh) has exploded in the Whirlpool Galaxy (M51), and now astronomers have identified its unusual progenitor using data from Gemini NIRI.
The image of Kronberger 61, discovered by Austrian amateur astronomer Matthias Kronberger, is featured at an International Astronomical Union symposium on planetary nebulae this week in Spain’s Canary Islands. The research team’s work features a striking image of the new nebula obtained with the Gemini Observatory.
An international team of astronomers discovered the most distant known supermassive black hole, seen as a luminous quasar caused by gas falling into the black hole.
In early April 2011, after more than a decade of effort, the Gemini Multi-Conjugate Adaptive Optics System (GeMS) saw starlight for the first time.
An international team of astronomers using the Gemini North telescope revealed that a powerful outburst of radiation originated from a massive black hole at the center of a distant galaxy.
The chance alignment of a pair of helium white dwarfs – both originally about the mass of the Sun – is showing how binary stars interact and eventually suffer a long slow demise.
A unique set of images from the Gemini North telescope in Hawai‘i allowed the researchers to estimate the distance of a GRB with a relatively high degree of certainty, placing it near the edge of the observable universe.
Two astronomers used the Gemini South telescope in Chile to obtain a dramatic new image of the nursery that could be described as psychedelic.
Spectroscopy obtained with the Gemini Near-Infrared Spectrograph (GNIRS) on the Gemini North telescope combined with photometry from the Spitzer Space Telescope enable the identification of a late-type brwon dwarf's spectral type as T8.5.
High school students from across Australia joined in a competition to obtain scientifically useful (and aesthetically pleasing) images using the Gemini Observatory. The winning image is an interacting galaxy pair NGC 6872 and IC 4970.
Seven years ago, Gemini Observatory began a modest program in our local Big Island community called Journey Through the Universe (JTtU).
For the first time, observations with the Gemini Observatory clearly reveal an extreme, large-scale galactic outflow that brings the cosmic dinner to a halt.
AstroDay Chile, which started as a mere handful of booths and kiosks from AURA observatories in 2005, has grown to host more than 17 institutions from Chile and beyond.
A new era in high-resolution astronomy began with the successful propagation of a 5-star sodium laser guide star "constellation" in the skies over Cerro Pachon in Chile.
