Probing the Atmosphere of an Extrasolar Planet with Gemini South

A group of British astronomers, led by Neale P. Gibson of the University of Oxford, used the Gemini Multi-Object Spectrograph (GMOS) to probe the atmosphere of a transiting extrasolar planet identified as WASP-29b.

Gemini and Subaru Telescopes Expand International Collaboration

The new time exchange agreement between Gemini and Subaru makes the entire suite of instrumentation available at each observatory open to any astronomer in the countries of the U.S., Japan, Canada, Australia, Brazil, Argentina, and Chile.

Poetry in Motion: Rare Polar-Ring Galaxy Captured in New Image

This new Gemini Legacy image captured the colorful and dramatic tale of a life-and-death struggle between two galaxies interacting.

Sharpest-ever Ground-based Images of Pluto and Charon: Proves a Powerful Tool for Exoplanet Discoveries

Using a method called reconstructive speckle imaging, the researchers took the sharpest ground-based snapshots ever obtained of Pluto and Charon in visible light, which hint at the exoplanet verification power of Gemini telescopes when combined with speckle imaging techniques.

The Best Standard Candle for Cosmology

When observed at near-infrared wavelengths, type Ia supernovae provide the greatest precision as “standard candles” for measuring cosmological distances.


A team, led by Edo Berger of Harvard University, made the most of a dying star’s fury to probe a distant galaxy some 9.5 billion light-years distant. The dying star is the most distant stellar explosion of its kind ever studied.

Astronomers Reassured by Record-breaking Star Formation in Huge Galaxy Cluster

The team, led by MIT's Michael McDonald, found evidence for extreme star formation, or a starburst, significantly more extensive than any seen before in the core of a giant galaxy cluster.
