Illumination of the Early Universe by Quasars: Korea's 1st Result as Limited Gemini Partner

A team of Korean astronomers discovered a faint quasar in the early Universe which sheds light on the main sources of illumination about 1 billion years after the Big Bang.

Back on the Sky at Gemini South

After 18 days of hard work during the recent scheduled maintenance shutdown, the Gemini South telescope is back on the sky! During maintenance, which took place October 13th - 30th, the 8.1-meter primary mirror received a fresh multi-layer protected silver coating - a key task for the shutdown.

Time Delay in Lensed Quasar: First Fast Turnaround Result

A team of Norwegian and US astronomers, using data from Gemini North and the Nordic Optical Telescope (NOT), have measured the time delay in images of a quasar lensed by a foreground cluster of galaxies

Mysterious Starburst Unshrouded in Nearby Galaxy

The nearest spiral galaxy with a nuclear starburst (greatly enhanced star formation near a galaxy’s center) is also the site of a long-standing astronomical mystery. The core of this galaxy is so shrouded by gas and dust that the exact location of its core has remained unresolved for years.

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.

Gemini-Discovered World is Most Like Jupiter

Going beyond the discovery and imaging of a young Jupiter, astronomers using the Gemini Observatory's new Planet Imager (GPI) have probed a newly discovered world in unprecedented detail.

Gemini Studies a Plethora of Brown Dwarfs Candidates

An international team of astronomers recently discovered 42 new brown dwarfs using data from the near-infrared imager and spectrograph Flamingos-2 at Gemini South and other telescopes in Chile and Hawai’i.

Seeing Where Stars Collide

Using the advanced adaptive optics system GeMS, on the Gemini South telescope, astronomers have imaged a beautiful stellar jewel-box – a tightly packed cluster of stars that is one of the few places in our galaxy where astronomers think stars can actually collide.

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.

Star Pair’s Dusty Disk Shines Light on Planet Formation

Astronomers using the Gemini South telescope in Chile have discovered striking new evidence for planet formation in a dusty disk surrounding a pair of stars in Sagittarius.

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.
