17 July 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 March 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.

20 July 2006: A high-resolution image released today by the Gemini Observatory shows Jupiter's two giant red spots brushing past one another in the planet's southern hemisphere.

8 June 2006: Massive star supernovae have been major "dust factories" ever since the first generations of stars formed several hundred million years after the Big Bang, according to an international study to be published in Science magazine on July 14, 2006.

5 June 2006: These results were announced by two teams of researchers during a press conference at the meeting that also included the release of new images of the entire span of M31 obtained with the Spitzer Space Telescope. The Gemini teams included Canadian researcher Tim Davidge (NRC, Herzberg Institute of Astrophysics, Victoria BC) and Knut Olsen of the National Optical Astronomy Observatory (NOAO). The new data about individual stars in M31 obtained with the Gemini North Telescope on Mauna Kea, Hawaii, demonstrate dramatically the complementarity of ground-based telescopes, which can record images with unprecedented spatial resolution, and space-based facilities, which have higher sensitivity.

20 October 2005: Like the little engine that could, geologic activity on the surface of Saturn's moon Titan–maybe outgassing cracks and perhaps icy Cryovolcanoes – is belching puffs of methane gas into the atmosphere of the moon, creating clouds.

15 September 2005: When NASA’s Deep Impact mission ploughed into comet 9P/Tempel 1 on July 4th of this year, the giant telescopes on Mauna Kea had a unique view of the massive cloud of dust, gas and ice expelled during the collision.

8 September 2005: Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust. The discovery might provide insights into our own solar system’s eventual demise several billion years from now.

26 August 2005: The Gemini Observatory released a pair of images today that capture the dynamics of two very different interactions in space. One is a cold, dark dust cloud that resembles an ethereal-looking Chinese dragon. The other shows a distant duo of galaxies locked in a knot-like embrace that could portend the long-term future of our own Milky Way galaxy.

29 July 2005: Gemini Observatory has obtained a preliminary spectrum of 2003 UB313, the so-called "10th planet". These observations were obtained on January 25, 2005 by Chad Trujillo, a Gemini staff member who is also on the discovery team for 2003 UB313, the existence of which was formally announced by the Minor Planet Center in Cambridge, MA on July 29, 2005. The discovery team (Mike Brown of Caltech, Chad Trujillo of Gemini and David Rabinowitz of Yale) are still uncertain of the exact size of the body, but report that it must be Pluto-sized or larger. The body is the most distant solar system body known to orbit the sun at 97 AU from the sun, over 3 times farther away than planet Pluto. The "planet" was originally discovered in late December 2004 with data collected from the Samuel Oschin 1.2 meter telescope at Palomar Mountain, CA.

20 July 2005: A relatively young star located about 300 light-years away is greatly improving our understanding of the formation of Earth-like planets.

17 May 2005: Using a giant telescope on Mauna Kea Hawaii is a dream for most amateur sky watchers. Recently a Canadian amateur astronomy group took advantage of a rare opportunity and used one of the largest telescopes in the world, the Gemini 8-meter telescope, to look more deeply into the remains of a particular stellar nursery than anyone ever has.

28 April 2005: LGS lasers have a total power output that is less than a refrigerator light bulb; Laser Guide Stars on Mauna Kea can not be used for any military-related activities; LGS lasers produce an artificial star that is invisible to the naked eye; Atmospheric scattering of LGS light is only dimly visible within a few hundred feet of an observatory; LGS are formed in a 6 mile (10 kilometer) thick layer of sodium in the atmosphere about 50 miles (90 kilometers) above the Earth’s surface. The high-altitude sodium is delivered by meteors burning up in our atmosphere.

1 January 2005: Like the annual New Year’s fireworks display, astronomers at Gemini Observatory are ushering in 2005 with a striking image that dazzles the eye with stellar pyrotechnics.

15 December 2004: Using adaptive optics on the Gemini North and Keck II telescopes on Mauna Kea, Hawai'i, a U.S. team has discovered a new phenomenon in the atmosphere of Saturn’s largest moon Titan.

8 October 2004: Until now, astronomers have been nearly blind when looking back in time to survey an era when most stars in the Universe were expected to have formed. This critical cosmological blind-spot has been removed by a team using the Frederick C. Gillett Gemini North Telescope, showing that many galaxies in the young Universe are not behaving as expected some 8-11 billion years ago.

5 October 2004: Astronomers using the Gemini North and Keck II telescopes have peered inside a violent binary star system to find that one of the interacting stars has lost so much mass to its partner that it has regressed to a strange, inert body resembling no known star type.

25 May 2004: Quasars are the most brilliant of cosmic fireworks, shining out across billions of light-years of space. However, a recent study done at Gemini Observatory shows that they appear to blaze forth from humdrum galaxies in the early universe, and surprisingly, not from the giant or disrupted ones astronomers expected.

30 March 2004: A timely discovery by American amateur astronomer Jay McNeil, followed immediately by observations at the Gemini Observatory, has provided a rare glimpse into the slow, yet violent birth of a star about 1,500 light-years away. The resulting findings reveal some of the strongest stellar winds ever detected around an embryonic Sun-like star.

26 January 2004: Like a doctor trying to understand an elderly patient's sudden demise, astronomers have obtained the most detailed observations ever of an old but otherwise normal massive star just before and after its life ended in a spectacular supernova explosion.
