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.
After more than a year of studying the 2009 collision with Jupiter, a team's results indicate that the colliding body was rocky and not an icy comet like the last known collision with Jupiter.
On the night of January 21-22, 2011 the Gemini South 50-watt laser began on-sky engineering testing and commissioning with its successful propagation into the sky over the summit of Cerro Pachón in Chile.
Astronomers have measured the most massive known black hole in our cosmic neighborhood by combining data from a giant telescope in Hawai'i and a smaller telescope in Texas.
New work led by Andrea Dupree (Harvard-Smithsonian Center for Astrophysics) now shows direct evidence for helium abundance variations—a sign of multiple histories—in the bright globular cluster Omega Centauri.
On December 6-8, 2010 about a dozen representatives from AURA converged at Gemini’s base facility in Hilo, Hawai‘i to discuss a broad range of topics related to diversity in the workforce.
The composite image, taken on Nov. 18, 2010 by the Gemini North telescope in Hawaii, shows a belt that had previously vanished in Jupiter's atmosphere is now reappearing.
The discovery of an unusual stellar system combined with Gemini North NIRI observations has allowed astronomers to confirm the spectral type of a cool methane dwarf and determine its temperature, mass, and age with confidence.
