Gemini South Telescope Captures Exquisite Planetary Nebula

The image showcases the striking planetary nebula CVMP 1. This object is the result of the death throes of a giant star. As the progenitor star of this planetary nebula slowly cools, this celestial hourglass will run out of time and will slowly fade.

Fast Radio Burst Observations Deepen Astronomical Mystery

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.

A Galactic Dance

The international 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.

Planning for a New Era in Astronomy Communication

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 Helps Map Larger than Expected Structure of Ancient Supercluster

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.

Two Ancient Migration Events in the Andromeda Galaxy

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.

Record-Breaking Protocluster Takes Fast-track

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.

Gemini Observatory Captures Multicolor Image of First-ever Interstellar Comet

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.

Exoplanets Can’t Hide Their Secrets from Innovative New Instrument

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.

Revealing the Intimate Lives of MASSIVE Galaxies

Gemini Observatory’s MASSIVE Galaxy Survey peeks into the lives of some of the most interesting galaxies of the universe.

Total Annihilation for Supermassive Stars

Gemini Observatory captures critical data on an exotic stellar explosion that’s challenging astronomers to rethink how the most massive stars end their lives.

Discovering Patterns in Io's Volcanoes

Jupiter’s volcanic moon Io brought astronomers and geologists together to reveal that this moon’s hot spots fluctuate on unexpected timescales.

Einstein's General Relativity Illustrated by a Single Star

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.

Cosmic Cat and Mouse: Astronomers Capture and Tag a Fleeting Radio Burst

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.

The Formative Years: Giant Planets vs. Brown Dwarfs

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.

Gemini Focuses on a Mid-sized Galactic Black Hole

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.”

Is the Mystery of the Dark Matter Deficient Galaxy Resolved?

Two teams of researchers came to different conclusions regarding dark matter in NGC 1052-DF2 (KKS2000-04).

Neptune’s Moon Triton Fosters Rare Icy Union

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.
