26 Septiembre 2019: The discovery of the most distant large-scale cluster of galaxies in the very young Universe has astronomers puzzling over how it formed so rapidly.

11 Junio 2019: 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.

6 Junio 2019: 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.”

20 Mayo 2019: Astronomers using the Gemini Observatory explore Neptune’s largest moon Triton and observe, for the first time beyond the lab, an extraordinary union between carbon monoxide and nitrogen ices. 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.

21 Marzo 2019: Using high-resolution adaptive optics imaging from the Gemini Observatory, astronomers have uncovered one of the oldest star clusters in the Milky Way Galaxy. The remarkably sharp image looks back into the early history of our Universe and sheds new insights on how our Galaxy formed.

9 Enero 2019: Observations from Gemini Observatory identify a key fingerprint of an extremely distant quasar, allowing astronomers to sample light emitted from the dawn of time. Astronomers happened upon this deep glimpse into space and time thanks to an unremarkable foreground galaxy acting as a gravitational lens, which magnified the quasar’s ancient light. The Gemini observations provide critical pieces of the puzzle in confirming this object as the brightest appearing quasar so early in the history of the Universe, raising hopes that more sources like this will be found.

1 Noviembre 2018: 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. It also provides a unique glimpse into the conditions present in the young Universe shortly after the Big Bang.

20 Septiembre 2018: 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.

2 Agosto 2018: 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.

24 Julio 2018: An agreement between the Korea Astronomy and Space Science Institute (KASI) and the agencies that own and operate the International Gemini Observatory was signed today that established the Republic of Korea as a full Participant in the Gemini Observatory.

22 Mayo 2018: 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. The sequence shows the glow from an extensive region of fissures over the course of a single night (May 21-22). During the sequence, multiple fissures expelled lava in the area in and around Leilani Estates in the Puna district of the Big Island of Hawai‘i. The lava also flowed into the ocean during the period of the video.

23 Abril 2018: Hydrogen sulfide, the gas that gives rotten eggs their distinctive odor, permeates the upper atmosphere of the planet Uranus – as has been long debated, but never definitively proven. Based on sensitive spectroscopic observations with the Gemini North telescope, astronomers uncovered the noxious gas swirling high in the giant planet’s cloud tops. This result resolves a stubborn, long-standing mystery of one of our neighbors in space

28 Marzo 2018: 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. Since the Universe is dominated by dark matter, and it is the foundation upon which galaxies are built, “...this is a game changer,” according to Principal Investigator Pieter van Dokkum of Yale University.

6 Diciembre 2017: Observations reveal the mass of earliest known supermassive black hole which radiates from an era in the universe only 690 million years after the Big Bang. Researchers, using unique spectroscopic data from Gemini Near-Infrared Spectrograph (GNIRS) on Gemini North determined its mass at a whopping 800 million times the mass of our Sun.

20 Noviembre 2017: Gemini Observatory provided key observations in characterizing an object visiting from outside our solar system, ‘Oumuamua. After the object was discovered by Pan-STARRS1 on Haleakala, both Gemini telescopes dropped everything to observe ‘Oumuamua for three nights as it quickly dimmed from view. Researchers found that despite its interstellar origin, the object is similar in composition to some objects in our Solar System but its shape is unlike anything found around our Sun.

3 Noviembre 2017: Gemini Observatory, using the Near-Infrared Integral Field Spectrograph on the Gemini North telescope in Hawai‘i, has confirmed the spiral nature of what is now the most distant known spiral galaxy. The galaxy's light, revealing how the galaxy looked some 11 billion years ago, is gravitationally lensed by a massive foreground cluster of galaxies to help reveal the distant pinwheel nature of the galaxy.

16 Octubre 2017: Gemini Observatory "pulled all of the stops" to bring a gravitational wave source into focus and capture early optical and infrared light from the merger of two neutron stars. The critical ground-based observations spanned almost a month during the summer of 2017 and allowed astronomers to dissect the first electromagnetic light emissions ever associated with a gravitational wave event.

17 Agosto 2017: By combining the light collecting power of Gemini North's 8-meter mirror with a high-resolution spectrograph at the neighboring Canada-France-Hawaiʻi Telescope on Maunakea, astronomers probe a speeding bullet in our galaxy. The researchers suggest that the celestial speedster is likely a white dwarf star expelled from a supernova explosion and sent hurtling through our galactic neighborhood some 50 million years ago.

30 Junio 2017: Very detailed Gemini Observatory images peel back Jupiter’s atmospheric layers to support the NASA/JPL Juno spacecraft in its quest to understand the giant planet’s atmosphere.

2 Junio 2017: Gemini Observatory astronomer Meg Schwamb is this year’s recipient of the Carl Sagan Medal for Excellence in Public Communication in Planetary Science. The prize is awarded annually by the Division for Planetary Sciences (DPS) of the American Astronomical Society (AAS). Schwamb is being honored for the creation and development of new tools and venues to facilitate planetary science communication. She will receive the medal in October at the Division of Planetary Sciences’ annual meeting hosted in Provo, Utah.
