  • Lonely Black Hole Relic Shines Light on Young Universe

    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.

  • Celebrating 12 Years of Journey Through the Universe (and Counting!)

    During the week of March 7-11, 83 observatory professionals consisting of astronomers, engineers, astronomy educators, and other observatory staff brought their passion for science into hundreds of local Hawai'i Island classrooms as a part of Gemini Observatoryʻs flagship annual outreach program, Journey Through the Universe.

  • The Fastest Quasar Ultraviolet Wind

    Observations using the Gemini Multi-Object Spectrographs (GMOS) on both Gemini North and South telescopes have revealed the fastest ultraviolet wind ever measured in a quasar.

  • Supermassive Black Hole - That Wasn't

    Research shows that supermassive black holes like to be the only residents on the block, as stars too close to them end up being thrown vast distances from the galaxy's center.

  • Are the Coolest Brown Dwarfs Loners?

    Astronomers use Gemini’s high-resolution multi-conjugate adaptive optics system to look for elusive companions to the lowest mass brown dwarfs.

  • Gemini Confirms a Free-Floating Planet

    An extremely red planetary-mass object is confirmed, based on Gemini observations, to be a free-floating member of the Beta Pictoris moving group. This is one of only a handful of directly imaged planets available for spectroscopy – allowing scientists to probe the world’s physical characteristics.

  • Nightly Base Facility Operations at Gemini North!

    Base Facility Operations (BFO) are now fully implemented for the Gemini North telescope. All operations are now routinely conducted each night from the Hilo Base Facility.

  • Gemini Helps Confirm Dark “Noodles” in Milky Way

    Clumps of gas shaped like noodles could be floating around in our Galaxy, radically challenging our understanding of gas conditions in the Milky Way.

  • Gap in Dusty Disk is Likely Embryonic Sub-Jupiter Mass Planet

    At just 180 light years from Earth and a ripe young age of roughly 8 million years, this nearly solar-mass star and its orbiting, circumstellar disk of dust and gas are prime targets to better understand the processes involved in star and planet formation

  • Gemini and Keck Put New Spin on Galaxy Formation

    A team of Australian researchers used two Maunakea-based observatories – Gemini North and W. M. Keck Observatory – to discover why some galaxies are clumpy rather than spiral in shape and it appears that low spin is to blame.

  • Gemini Featured at Extreme Solar Systems III Conference

    Observations using the Gemini Planet Imager are featured prominently at the Extreme Solar Systems III meeting which occurred Nov. 29 - December 4 2015 in Waikoloa Hawai‘i. Below are two results from a press conference on December 1, 2015.

  • Gemini Characterizes Cheshire Cat

    Gemini observations provide a key scientific context for a striking new image of the gravitationally lensed galaxy group popularly known as the Cheshire Cat. Gemini played a critical role in the image’s scientific story by taking the spectral fingerprints of many of the galaxies that make up the foreground cluster which bends the distant galactic light

  • Gemini Planet Imager Exoplanet Survey – One Year into the Survey

    The Gemini Planet Imager Exoplanet Survey (GPIES) is an ambitious three-year study dedicated to imaging young Jupiters and debris disks around nearby stars using the GPI instrument installed on the Gemini South telescope in Chile.

  • Illumination of the Early Universe by Quasars: Korea's 1st Result as Limited Gemini Partner

    A team of Korean astronomers discovered a faint quasar in the early Universe which sheds light on the main sources of illumination about 1 billion years after the Big Bang.

  • Back on the Sky at Gemini South

    After 18 days of hard work during the recent scheduled maintenance shutdown, the Gemini South telescope is back on the sky! During maintenance, which took place October 13th - 30th, the 8.1-meter primary mirror received a fresh multi-layer protected silver coating - a key task for the shutdown.

  • Time Delay in Lensed Quasar: First Fast Turnaround Result

    A team of Norwegian and US astronomers, using data from Gemini North and the Nordic Optical Telescope (NOT), have measured the time delay in images of a quasar lensed by a foreground cluster of galaxies

  • Gemini Launches Local Students on an Exciting Week-long Viaje al Universo

    Gemini Observatory kicked off its week-long program Viaje al Universo with an opening ceremony at the University of La Serena. The annual program is an immersive week of fun, hands-on learning focusing on local students and teachers.

  • Mysterious Starburst Unshrouded in Nearby Galaxy

    The nearest spiral galaxy with a nuclear starburst (greatly enhanced star formation near a galaxy’s center) is also the site of a long-standing astronomical mystery. The core of this galaxy is so shrouded by gas and dust that the exact location of its core has remained unresolved for years.

  • The Deepest Ground-based Photometry in a Crowded Field

    Expecting to resolve stars deep into the crowded field of a globular cluster is a tall order for ground-based telescopes. However, Paolo Turri (University of Victoria, Canada) and colleagues have used the Gemini Multi-conjugate adaptive optics System (GeMS) with the Gemini South Adaptive Optics Imager (GSAOI) to do just that.
