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.

4 Abril 2017: It’s a kinder, gentler Neptune, says Gemini astronomer Meg Schwamb in describing a new result that leaves little doubt about how Neptune gently swept a class of planetoid pairs into the outer Solar System.

5 Enero 2017: Gemini Observatory provides critical rapid follow up observations of a Fast Radio Burst – one of modern astronomy's greatest enigmas. These observations provide the first details on a burst's distant extragalactic host.

24 Agosto 2016: Using the world’s most powerful telescopes, an international team of astronomers has discovered a massive galaxy that consists almost entirely of Dark Matter. Using the W. M. Keck Observatory and the Gemini North telescope – both on Maunakea, Hawai‘i – the team found a galaxy whose mass is almost entirely Dark Matter. The findings are being published in The Astrophysical Journal.

5 Abril 2016: 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.

25 Septiembre 2015: A new Gemini Observatory image reveals the remarkable “fireworks” that accompany the birth of stars. The image captures in unprecedented clarity the fascinating structures of a gas jet complex emanating from a stellar nursery at supersonic speeds. The striking new image hints at the dynamic (and messy) process of star birth. Researchers believe they have also found a collection of runaway (orphan) stars that result from all this activity..

26 Noviembre 2013: Gemini observations support an unexpected discovery in the galaxy Messier 101. A relatively small black hole (20-30 times the mass of our Sun) can sustain a hugely voracious appetite while consuming material in an efficient and tidy manner – something previously thought impossible. The research also affects the long quest for elusive intermediate-mass black holes. The findings are published in the November 28, 2013, issue of the journal Nature.

29 Mayo 2013: Images of Comet ISON over the past three months hint at coming changes as comet speeds into the inner solar system.

21 Diciembre 2012: Potential asteroid collision in 2040 is a non-threat based on new Gemini Observatory data.

17 Octubre 2012: When the lamp is shattered,
The light in the dust lies dead.
When the cloud is scattered,
The rainbow's glory is shed.

29 Agosto 2012: Nature hath no fury like a dying star – and astronomers couldn’t be happier…

14 Mayo 2012: A new Legacy Image from the Gemini Observatory reveals the remarkable complexity of the planetary nebula Sharpless 2-71 (Sh 2-71). Embroiled in a bit of controversy over its “birth parents” the nebula likely resulted from interactions between a pair of two old and dying stars. Legacy images like this one share the stunning beauty of the universe as revealed by the twin 8-meter Gemini telescopes in Hawai‘i and Chile.

25 Julio 2011: In a partnership between amateur and professional astronomers, the recent discovery of a dying star’s last gasps could help resolve a decades-old debate among astronomers. That is, are stellar companions key to the formation and structure of planetary nebulae?

25 Mayo 2011: In a game of cosmological one-upmanship, what is likely the most distant gamma ray burst (GRB) ever detected could be presenting humanity with a glimpse back to within about half a billion years of the Big Bang. "Like any finding of this sort there are uncertainties,” said the study's principal investigator Antonino Cucchiara. “However, if I were in Vegas, I would never bet against the odds that this is the most distant GRB ever seen and we estimate that there is even a 23% chance that it is the most distant object ever observed in the universe."

23 Febrero 2011: When two galaxies merge to form a giant, the central supermassive black hole in the new galaxy develops an insatiable appetite. However, this ferocious appetite is unsustainable.

11 Febrero 2010: A dramatic new image from the Gemini North telescope illustrates the dynamic and sometimes violent process of star birth. It also demonstrates the capabilities of new filters available to researchers using the Gemini Multi-Object Spectrograph (GMOS).

21 Mayo 2008: Astronomers have observed the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time. While observing supernova 2007uy with the Swift X-ray Telescope, Alicia Soderberg and Edo Berger (Princeton University) discovered a mysterious X-ray flash elsewhere in the galaxy NGC 2770 located about 90 million light years away (Figure 1). Within a few hours observatories around the world scrambled to study its light. In a rapid sequence of events the Gemini North telescope was able to capture and dissect the object’s light in a set of optical spectra that contains the earliest spectrum ever obtained of a massive star ending its life in a supernova explosion outside of our galaxy’s neighborhood.

28 Noviembre 2007: A dwarf star with a surprisingly magnetic personality and a huge hot spot covering half its surface area is showing astronomers that life as a cool dwarf is not necessarily as simple and quiet as they once assumed.

8 Junio 2006: Massive star supernovae have been major "dust factories" ever since the first generations of stars formed several hundred million years after the Big Bang, according to an international study to be published in Science magazine on July 14, 2006.
