Astronomers have pinpointed the origin of a repeating Fast Radio Burst to a nearby spiral galaxy, challenging theories on the unknown source of these pulses.
Gemini Observatory of NSF's OIR Lab captured the image of the interacting galaxy pair NGC 5394/5 using the Gemini Multi-Object Spectrograph at Gemin North.
GEMMA project brought together science communications professionals to explore the unique opportunities and challenges of communicating Multi-Messenger and Time-Domain Astronomy, two rapidly growing fields in astronomy.
Gemini Observatory and Subaru Telescope uncover the massive (and larger than expected) structure of a distant supercluster. Mapping the formation of these ancient superclusters is a critical step in understanding the dark matter and dark energy that shape these structures.
Astronomers have uncovered two historic events in which the Andromeda Galaxy underwent major changes to its structure. The findings shed light not only on the evolution and formation of the Andromeda Galaxy, but to our own Milky Way Galaxy as well.
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.
The first-ever comet from beyond our Solar System has been successfully imaged by the Gemini Observatory in multiple colors. The image of the newly discovered object, denoted C/2019 Q4 (Borisov), was obtained on the night of 9-10 September using the Gemini Multi-Object Spectrograph on the Gemini North Telescope on Hawaii’s Maunakea.
A cunning new instrument at Gemini Observatory has achieved what was once thought impossible — namely, the characterization of an exoplanet orbiting a binary star and determining which star of the pair it orbits.
Gemini Observatory’s MASSIVE Galaxy Survey peeks into the lives of some of the most interesting galaxies of the universe.
Gemini Observatory captures critical data on an exotic stellar explosion that’s challenging astronomers to rethink how the most massive stars end their lives.
Jupiter’s volcanic moon Io brought astronomers and geologists together to reveal that this moon’s hot spots fluctuate on unexpected timescales.
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.
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.
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.
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.”
Two teams of researchers came to different conclusions regarding dark matter in NGC 1052-DF2 (KKS2000-04).
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.
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.
Using high-resolution adaptive optics imaging from the Gemini Observatory, astronomers have uncovered one of the oldest star clusters in the Milky Way Galaxy.
