Helium’s Role in the Pulsation of Early White Dwarfs

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.

Gemini Identifies Free-floating Jupiter Analogue

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).

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.

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

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.
