12 Enero 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.

24 Noviembre 2010: This image is a composite of three color images taken on Nov. 18, 2010, by the Gemini North telescope in Hawaii. The composite image shows a belt that had previously vanished in Jupiter's atmosphere is now reappearing.

9 Septiembre 2010: Observing a fireball streaking through the atmosphere of another planet is a rare occurrence. However, two amateur astronomers did just that on June 3, 2010. Their images prompted the twin Gemini Observatory telescopes in Hawai‘i and Chile to join other telescopes around (and above) the world to see if the object left any trace of its passage into Jupiter’s cloudtops.

29 Junio 2010: A planet only about eight times the mass of Jupiter has been confirmed orbiting a Sun-like star at over 300 times farther from the star than the Earth is from our Sun. The newly confirmed planet is the least massive planet known to orbit at such a great distance from its host star. The discovery utilized high-resolution adaptive optics technology at the Gemini Observatory to take direct images and spectra of the planet.

25 Mayo 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.

12 Mayo 2010: A newly discovered gravitational lens in a relatively nearby galaxy cluster is leading astronomers to conclude that the cluster hosts the most massive galaxy known in our local universe. The study also reaffirms that galactic cannibalism is one reason that this galaxy is so obese, tipping the scales at up to 30 trillion times the mass of our Sun.

6 Abril 2010: The cliché that youth grow up so fast is about to take on a new twist. This is due to the discovery of a very young planet-like object (with a mass somewhere between 5-10 times that of Jupiter), paired with a low-mass brown dwarf. What is unique about this system is that the planet-like body appears to have formed in about a million years–more rapidly than some theories of planet formation predict.

11 Febrero 2010: A dramatic new image from the Gemini North telescope illustrates the dynamic and sometimes violent process of star birth. It also demonstrates the capabilities of new filters available to researchers using the Gemini Multi-Object Spectrograph (GMOS).

27 Enero 2010: Explaining how the most massive stars are born, deep within their stellar nurseries, is one of the most persistent mysteries in modern astronomy. Now, observations at the Gemini Observatory provide convincing new evidence that these stellar heavyweights may be born in much the same manner as lightweights like our Sun.

5 Enero 2010: Using the Gemini South telescope in Chile, astronomers at UCLA have found dusty evidence for the formation of young, rocky planets around a star some 500 light years distant. But these potential extrasolar worlds are alien in an even more intriguing way… In the aftermath of collisions between planetary embryos around this star the researchers discovered that the dusty debris bears no resemblance to the planetary building blocks of our own Solar System.

4 Enero 2010: Using adaptive optics to remove atmospheric blurring, Gemini Observatory released an image today showing previously hidden forensic secrets at the ballistic core of the Homunculus Nebula, part of the explosive Eta Carinae star system.

12 Agosto 2009: While far from a tropical rain forest, the equatorial region of Saturn’s largest moon, Titan, has recently displayed tantalizing evidence that the parched, dry, ultra-frigid desert can support large-scale storms.

5 Agosto 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.

23 Julio 2009: Jupiter is sporting a glowing bruise after getting unexpectedly whacked by a small solar system object, according to astronomers using the Gemini North telescope on Mauna Kea in Hawai'i. A spectacular new mid-infrared image is available for download on this page.

30 Abril 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.

1 Abril 2009: On the nights of April 2-3 (3-4 UT) both Gemini telescopes participated in the “Around the World in 80 Telescopes” live, around the world control room webcast. Gemini was honored to be the first control room visit for the event when at 11:00 pm (HST) on April 2nd (9:00 am UT on April 3rd) Gemini presented a new video introduction to Gemini followed by a live visit to the Gemini North control room on Hawaii’s Mauna Kea hosted by Gemini’s Scott Fisher. Nineteen hours later, Gemini South participated in the event at Midnight (Chile time) on the night of April 3-4 (4:00 am UT on April 4th) when Gemini South astronomer Etienne Artigau hosted a visit to the Gemini South control room in Chile.

9 Noviembre 2008: Astronomers using the Gemini and Keck observatories obtain first direct images of a planetary family around a normal star

14 Septiembre 2008: Astronomers have unveiled what is likely the first picture of a planet around a normal star similar to the Sun.

10 Septiembre 2008: Astronomers have been puzzling over the engine behind the historical 1843 outburst of Eta Carinae since it happened, but new observations with the Gemini South and the Blanco telescopes in Chile add a startling new clue.

26 Junio 2008: In what appears to be a masterful illusion, astronomers at Gemini Observatory have imaged two nearly identical spiral galaxies in Virgo, 90 million light years distant, in the early stages of a gentle gravitational embrace. The new image was obtained at the Gemini South telescope in Chile using GMOS, the Gemini Multi-Object Spectrograph.
