Using the Gemini Planet Imager astronomers have successfully monitored the motion of a planet around the forming exoplanet system orbiting the star HD 95086 and suggest that more unseen planets are present.
Before low-medium mass stars become white dwarfs they pulsate wildly and eventually spew their outer layers into space – often forming beautiful planetary nebulae. The same stars are predicted to continue pulsating during their transformation to a white dwarf, if they have helium in their atmospheres.
Using the FLAMINGOS-2 spectrometer/imager at Gemini South, astronomers have characterized an especially young, free-floating analogue to Jupiter in our neighborhood (92 light years away).
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.
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.
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.
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.
Astronomers use Gemini’s high-resolution multi-conjugate adaptive optics system to look for elusive companions to the lowest mass brown dwarfs.
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.
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.
Clumps of gas shaped like noodles could be floating around in our Galaxy, radically challenging our understanding of gas conditions in the Milky Way.
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
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.
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 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
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.
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.
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.
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 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.
