25 Mayo 2011: In a game of cosmological one-upmanship, what is likely the most distant gamma ray burst (GRB) ever detected could be presenting humanity with a glimpse back to within about half a billion years of the Big Bang. "Like any finding of this sort there are uncertainties,” said the study's principal investigator Antonino Cucchiara. “However, if I were in Vegas, I would never bet against the odds that this is the most distant GRB ever seen and we estimate that there is even a 23% chance that it is the most distant object ever observed in the universe."

23 Febrero 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 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.

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.

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.

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.

21 Mayo 2008: Astronomers have observed the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time. While observing supernova 2007uy with the Swift X-ray Telescope, Alicia Soderberg and Edo Berger (Princeton University) discovered a mysterious X-ray flash elsewhere in the galaxy NGC 2770 located about 90 million light years away (Figure 1). Within a few hours observatories around the world scrambled to study its light. In a rapid sequence of events the Gemini North telescope was able to capture and dissect the object’s light in a set of optical spectra that contains the earliest spectrum ever obtained of a massive star ending its life in a supernova explosion outside of our galaxy’s neighborhood.

28 Noviembre 2007: A dwarf star with a surprisingly magnetic personality and a huge hot spot covering half its surface area is showing astronomers that life as a cool dwarf is not necessarily as simple and quiet as they once assumed.

14 Noviembre 2007: 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.

17 Julio 2007: Frigid geysers spewing material up through cracks in the crust of Pluto’s companion Charon and recoating parts of its surface in ice crystals could be making this distant world into the equivalent of an outer solar system ice machine.

22 Marzo 2007: An image released today by the Gemini Observatory brings into focus a new and remarkably detailed view of supersonic "bullets" of gas and the wakes created as they pierce through clouds of molecular hydrogen in the Orion Nebula. The image was made possible with new laser guide star adaptive optics technology that corrects in real time for image distortions caused by Earth's atmosphere.
