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

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.

Gemini Confirms Maverick New Moon of Jupiter

Scientists announced the discovery of 12 new moons orbiting the planet Jupiter, including one that orbiting in the opposite direction from others of its ilk, which was confirmed by Gemini GMOS observations.

Elusive Intermediate Mass Black Hole Revealed by Cosmic Belch

The frustrating search for intermediate mass black holes is advancing thanks to Gemini observations of a “belch” which escaped when a black hole devoured a star.

Can Exoplanets Form in a Binary Star System?

A new study using DSSI on both Gemini telescopes reveals that the ratio of binary stars in Kepler’s K2 exoplanet host stars is similar to that found elsewhere in our neighborhood of the Milky Way.

Gemini Observatory Cloud Camera Captures Volcano’s Dramatic Glow

A camera used at the Gemini North telescope to monitor sky conditions from Hawaii’s Maunakea captured a remarkable time-lapse sequence of the Kīlauea volcanic eruption.

Massive Cluster Galaxies Move in Unexpected Ways

Astronomers using data from GMOS-North and GMOS-South) measured the motions of stars within a sample of BCGs and found the stellar motions inconsistent with these galaxies’ solitary cousins.

What Do Uranus’s Cloud Tops Have in Common With Rotten Eggs?

Based on sensitive spectroscopic observations with the Gemini North telescope, astronomers uncovered the noxious gas swirling high in Uranus’s cloud tops.

Dark Matter is a No Show in Ghostly Galaxy

Astronomers using data from the Gemini and W. M. Keck Observatories in Hawai‘i have encountered a galaxy that appears to have almost no dark matter. “...This is a game changer,” according to Principal Investigator Pieter van Dokkum of Yale University.
