The Deepest Ground-based Photometry in a Crowded Field

Expecting to resolve stars deep into the crowded field of a globular cluster is a tall order for ground-based telescopes. However, Paolo Turri (University of Victoria, Canada) and colleagues have used the Gemini Multi-conjugate adaptive optics System (GeMS) with the Gemini South Adaptive Optics Imager (GSAOI) to do just that.

Searching for Orphan Stars Amid Starbirth Fireworks

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.

Discovery Harkens to Early Solar System

Using the Gemini Planet Imager (GPI) at the Gemini South telescope in Chile, astronomers have discovered a young, emerging planetary system that shares remarkable similarities to our own Solar System in its infancy.

Don’t Blink: A Light Show in a Dynamic Stellar Nursery

In the cosmic “blink of an eye,” astronomers have detected rapid changes in brightness and appearance of a restless stellar nursery in Orion.

Orion’s Fingers: New Clarity on an Explosive Outflow

With new observations using adaptive optics imaging from Gemini South, John Bally of the University of Colorado and colleagues find over 120 high-velocity outflows in the “Orion Fingers.”

FAR FROM HOME: WAYWARD CLUSTER IS BOTH TINY AND DISTANT

Astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way’s “suburbs.” It is located where astronomers have never spotted such a small cluster of stars before.

Supermassive Black Hole Lurks at Dawn of the Universe

Infrared observations with the Gemini North telescope have confirmed a 12 billion solar mass black hole in an exceptionally bright quasar in the very early universe. The finding, led by a Chinese team, used Gemini and other telescopes to discover and characterize an extremely massive black hole from a period when the universe was very young.

Gemini’s "Fast Turnaround" Observing Mode is LIVE!

As of January 2nd, 2015, Gemini’s Fast Turnaround (FT) program is open for business. Following the first proposal deadline on January 31st, the Gemini community is now able to submit proposals every month for the duration of this open-ended trial.

THE GEMINI PLANET IMAGER PRODUCES STUNNING OBSERVATIONS IN ITS FIRST YEAR

Stunning exoplanet images and spectra from the first year of science operations with the Gemini Planet Imager (GPI) were featured today in a press conference at the 225th meeting of the American Astronomical Society (AAS) in Seattle, Washington.

Galactic Herding: New Image Brings Galaxy Diversity to Life

A compelling new image from Gemini Observatory peers into the heart of a group of galaxies (VV166) traveling through space together. The variety of galactic forms range from a perfect spiral, to featureless blobs and present, at a glance, a sampling of the diversity and evolution of galaxies.

Gemini Images Comet Hours Before Probe’s Landing

New Gemini Observatory images show an Earth-based perspective of the comet targeted by the Rosetta spacecraft. The images capture the comet about nine hours before the Philae probe landed on the “dirty snowball’s” surface.

First Surface Observations of Oort Cloud Objects

Astronomers are announcing today the discovery of two unusual objects in comet-like orbits that originate in the Oort cloud but with almost no activity, giving scientists a first look at their surfaces.

Quenching Star Formation in Cluster Galaxies

An international team using data from the Gemini Cluster Astrophysics Spectroscopic Survey to explore galaxies that have recently stopped (quenched) the formation of stars. Their findings reveal that these quenched galaxies tend to be closer to the cluster’s center and moving especially fast.

A Pair of Stellar Corpses Surrenders Secrets

The observations, led by Mukremin Kilic of the University of Oklahoma, reveal a unique, very close pairing of stellar corpses that have different evolutionary histories: one is the extremely dense, mountain-sized remains of a supernova explosion, and the other is a Neptune-sized cooling ember of a deceased Sun-like star that pulsates about every 30 minutes.
