One of those groups recently re-imaged their discovered system with the same instrument — the Gemini North telescope on Mauna Kea in Hawaii. David Lafrenière of the University of Montréal and Ray Jayawardhana and Marten H. van Kerkwijk of the University of Toronto have confirmed that the object they initially imaged is indeed a companion planet to the young star 1RXS J160929.1–210524...

Taking a narrow view of a lopsided galaxy
June 1st, 2010 - Astronomy
The starburst galaxy NGC 1313 is a stellar incubator delivering stars on a scale rarely seen in a single galaxy of its size. Now a striking new Gemini Observatory image reveals the multitudes of glowing gas clouds in this galaxy's arms. These colorful clouds are the telltale sign of star formation in this prolific star factory.

Researchers from the University of Minnesota in Minneapolis recorded the dip from the eruptive, luminous variable star using data from the Gemini South Telescope in Chile and the Hubble Space Telescope. Their results are detailed in a paper accepted for publication in Astrophysical Journal Letters. http://arxiv.org/PS_cache/arxiv/pdf/1004/1004.3529v3.pdf.
