Press Releases

5 April 2016: Astronomers using the 8-meter Gemini North telescope on Hawaii’s Maunakea have probed an enigmatic, and unexpected, supermassive black hole dominating the core of a large galaxy in the cosmic backwaters.

27 July 2015: Two undergraduates at San José State University have discovered two galaxies that are the densest known. Similar to ordinary globular star clusters but a hundred to a thousand times brighter, the new systems have properties intermediate in size and luminosity between galaxies and star clusters.

16 September 2014: A University of Utah astronomer and his colleagues discovered that an ultracompact dwarf galaxy harbors a supermassive black hole – the smallest galaxy known to contain such a massive light-sucking object. The finding suggests huge black holes may be more common than previously believed.

26 November 2013: Gemini observations support an unexpected discovery in the galaxy Messier 101. A relatively small black hole (20-30 times the mass of our Sun) can sustain a hugely voracious appetite while consuming material in an efficient and tidy manner – something previously thought impossible. The research also affects the long quest for elusive intermediate-mass black holes. The findings are published in the November 28, 2013, issue of the journal Nature.

6 August 2013: Gemini Observatory’s latest instrument, a powerful infrared camera and spectrograph at Gemini South, reveals its potential in a series of striking on-sky commissioning images released today.

17 October 2012: When the lamp is shattered,
The light in the dust lies dead.
When the cloud is scattered,
The rainbow's glory is shed.

24 April 2012: In mid-July 2012, astronomers from around the world will converge in San Francisco, California to discuss recent and future science from the Gemini Observatory. From direct imaging of exoplanets, to the most massive black holes ever measured, the meeting’s program features a wide-range of topics that are summarized on the conference’s webpage (above).

23 March 2012: Dr. William Smith, President of the Association of Universities for Research in Astronomy Inc. (AURA), announced today the selection of Dr. Markus Kissler-Patig as the new Director of the Gemini Observatory.

6 January 2012: Gemini’s next-generation adaptive optics system produces highest-resolution with largest field-of-view ever captured from the ground using laser guide star technology.

1 December 2011: Observations with the Gemini North telescope in Hawai‘i reveal evidence for what astronomers are calling the largest black holes ever measured in our nearby cosmological neighborhood. This result is crucial in explaining the long-standing mystery of where the largest black holes are hiding in our present-day universe.

29 March 2011: A New Gemini Podcast, In October of 2010, the Gemini South primary mirror received a shiny new coating of protected silver. A new two-part podcast allows you to experience an insider's view of this exciting process, one that few outside of Gemini have ever witnessed. Navigate to the Podcast by clicking on the video clip below.

23 February 2011: When two galaxies merge to form a giant, the central supermassive black hole in the new galaxy develops an insatiable appetite. However, this ferocious appetite is unsustainable.

12 January 2011: Astronomers led by Karl Gebhardt of The University of Texas at Austin 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. The result is an ironclad mass of 6.6 billion Suns for the black hole in the giant elliptical galaxy M87. This enormous mass is the largest ever measured for a black hole using a direct technique. Given its massive size, M87 is the best candidate for future studies to actually "see" a black hole for the first time, rather than relying on indirect evidence of their existence as astronomers have for decades.

25 May 2010: The starburst galaxy NGC 1313 is a stellar incubator delivering stars on a scale rarely seen in a single galaxy of its size. Now a striking new Gemini Observatory image reveals the multitudes of glowing gas clouds in this galaxy’s arms. These colorful clouds are the tell-tale sign of star-formation in this prolific star factory.

5 August 2009: Looking almost 11 billion years into the past, astronomers have measured the motions of stars for the first time in a very distant galaxy and clocked speeds upwards of one million miles per hour (about 1.6 million kilometers per hour), about twice the speed of our Sun through the Milky Way.

30 April 2009: The Gemini Observatory has released the first color image of what astronomers are calling the most distant object ever seen in the universe. The object is what is known as a Gamma-ray burst (GRB) which are the most energetic single events known in the universe.

4 March 2009: Finding a needle in a haystack might be easy compared to finding two very similar black holes closely orbiting each other in a distant galaxy.

7 October 2008: A deep new image of the Virgo cluster has revealed monumental tendrils of ionized hydrogen gas 400,000 light-years long connecting the elliptical galaxy M86 and the disturbed spiral galaxy NGC 4438.

2 April 2008: The well-known naked-eye star cluster Omega Centauri may be home to an elusive intermediate-mass black hole. Observations made using Gemini Observatory and Hubble Space Telescope provide convincing evidence that such black holes do exist and could even lead to an understanding of how they might evolve into larger supermassive black holes like the ones found at the cores of many galaxies.

9 January 2008: Observations of the interacting binary star using telescopes at Kitt Peak National Observatory and NASA’s Spitzer Space Telescope suggest that the disks of hot gas that accumulate around a wide variety of astronomical objects—from degenerate stars in energetic binary systems to supermassive black holes at the hearts of active galaxies—are likely to be much larger than previously believed.
