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.
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.
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.
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.
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.
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.
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.
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.
Based on sensitive spectroscopic observations with the Gemini North telescope, astronomers uncovered the noxious gas swirling high in Uranus’s cloud tops.
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.
The researchers exposed the identities of three ultra-faint dwarf galaxy candidates using the Gemini South telescope. They reports that the objects appear to be loose clusters of stars, not dwarf galaxies as some had previously believed.
A research team, using the Gemini South telescope, concludes that the majority of core collapse supernovae, exploding in luminous infrared galaxies, have previously not been found due to dust obscuration and poor spatial resolution.
Using the Gemini South telescope, researchers extracted spectra from extremely faint optical sources which they determined are nurseries of massive stars around an elliptical galaxy.
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.
Gemini observations played a critical role inidentifing an object which appears to be “photobombing” the Andromeda Galaxy. Rather than being a binary star system within the neighboring Andromeda Galaxy, the object is really a distant galaxy containing a supermassive black hole binary.
After the object was discovered by Pan-STARRS1 on Haleakala, both Gemini telescopes observed ‘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.
Gemini North’s NIFS has confirmed the spiral nature of the most distant known spiral galaxy (A1689B11) by far through gravitational lensing.
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.
Gemini astronomer Tom Geballe describes his recent infrared spectroscopic observations of a mysterious quintuplet of stars. Each of these stars is embedded in its own cocoon of dust in a cluster of massive stars near the center of the Milky Way.
Astronomers using the Gemini Observatory and the Canada-France-Hawaii Telescope have discovered remarkable differences in the abundance of heavier elements and the Lithium content in a binary star pair.
