Einstein's General Relativity Illustrated by a Single Star

By observing a single star orbiting around the supermassive black hole at the center of our Milky Way Galaxy, a team of astronomers have tested Einstein’s one hundred-year-old theory of General Relativity in an unprecedented new regime.

Cosmic Cat and Mouse: Astronomers Capture and Tag a Fleeting Radio Burst

Gemini Observatory provides critical observations that confirm the distance to a mysterious, very short-lived, radio outburst from a galaxy billions of light years away.

The Formative Years: Giant Planets vs. Brown Dwarfs

Based on preliminary results from a new Gemini Observatory survey of 531 stars with the Gemini Planet Imager (GPI), it appears more and more likely that large planets and brown dwarfs have very different roots.

Gemini Focuses on a Mid-sized Galactic Black Hole

An international team of researchers led by astronomer Jong-Hak Woo obtained deep spectroscopy from Gemini, combined with light echo measurements from multiple observatories, to confirm a black hole “missing link.”

Is the Mystery of the Dark Matter Deficient Galaxy Resolved?

Two teams of researchers came to different conclusions regarding dark matter in NGC 1052-DF2 (KKS2000-04).

Neptune’s Moon Triton Fosters Rare Icy Union

Using IGRINS on Gemini South, an extraordinary union between carbon monoxide and nitrogen ices has been observed. The discovery offers insights into how this volatile mixture can transport material across the moon’s surface via geysers, trigger seasonal atmospheric changes, and provide a context for conditions on other distant, icy worlds.

Making Good Use of Bad Weather: Finding Metal-poor Stars Through the Clouds

The Gemini telescopes helped to identify low-metallicity stars by gathering medium-resolution spectroscopic GMOS data for 666 bright stars under poor weather conditions. These data provide a unique opportunity to explore the chemical evolution of the Milky Way and look at the enrichment of star-forming gas clouds in the early Universe.

Ultra-sharp Images Make Old Stars Look Absolutely Marvelous!

Using high-resolution adaptive optics imaging from the Gemini Observatory, astronomers have uncovered one of the oldest star clusters in the Milky Way Galaxy.

Bubble Blowing Black Hole Jet’s Impact on Galactic Evolution

Astronomers using adaptive optics on Gemini North telescope have resolved, for the first time in near-infrared light, a giant elliptical galaxy with a young radio jet down to unprecedented scales

Cosmic Telescope Zooms in on the Beginning of Time

Observations from Gemini Observatory identify a key fingerprint of an extremely distant quasar, allowing astronomers to sample light emitted from the dawn of time.

Outer Solar System Object has Astronomers Seeing Double

Extremely high-resolution speckle observations by Gemini South deliver critical details on a star (or stars) lying in the apparent path of remnants from the early formation of our Solar System.

Large and Long Program 2019 CfP Released

Gemini Observatory announces the opportunity for new Large and Long Programs, with observations beginning in the 2019B semester.

Tiny Old Star Has Huge Impact

Astronomers use the Gemini Observatory to investigate a tiny star that is likely the oldest known star in the disk of our galaxy. The diminutive star could have a disproportionate impact on our understanding of the age and history of our Milky Way Galaxy.

Nearby Supernova Sheds Light on Ancient Dust

An international team used GNIRS to follow the evolution of the near-infrared spectrum of the core-collapse supernova 2017eaw (ccSN 2017eaw) over three semesters. The data obtained from this relatively nearby event may help us to better understand the existence of dusty galaxies in the early, much more distant Universe.

Gemini Observatory to Advance Adaptive Optics and Multi-messenger Astronomy with NSF Award

New funding from the National Science Foundation will enable the international Gemini Observatory to advance its position at the forefront of the new era of “multi-messenger astronomy” by enhancing its scientific capabilities in high-resolution and rapid-response astronomy.

GeMS “SERVS” Up Sharp Views of Young Galaxies in Early Universe

Multi-conjugate adaptive optics technology at Gemini South reveals that young galaxies, with large amounts of star formation, and actively growing central black holes, were relatively compact in the early Universe.

Dr. Jennifer Lotz Appointed Gemini Observatory Director

The Association of Universities for Research in Astronomy (AURA) is delighted to announce the appointment of Dr. Jennifer Lotz as the next Director of the Gemini Observatory. Dr. Lotz begins a five-year appointment as Gemini Director starting October 1, 2018. Previously, Dr. Lotz held the position of associate astronomer at the Space Telescope Science Institute (STScI).

Gemini Confirms the Most Distant Radio Galaxy

Using the Gemini North telescope in Hawai`i, an international team of astronomers from Brazil, Italy, the Netherlands, and the UK has discovered the most distant radio galaxy to date, at 12.5 billion light years, when the Universe was just 7% of its current age.

Astronomers Blown Away by Historic Stellar Blast

Observations from the Gemini South and other telescopes in Chile played a critical role in understanding light echoes from a stellar eruption which occurred almost 200 years ago. Gemini spectroscopy shows that ejected material from the blast is the fastest ever seen from a star that remained intact.

Republic of Korea Becomes a Full Participant in Gemini

The Korea Astronomy and Space Science Institute (KASI) signed an agreement that established the Republic of Korea as a full Participant in the Gemini Observatory.
