Astronomers have imaged a very young brown dwarf, or failed star, in a tight orbit around a young nearby sun-like star.
An international team led by University of Hawaii astronomers Beth Biller and Michael Liu with help from University of Arizona astronomer Laird Close and UA graduate students Eric Nielsen, Jared Males and Andy Skemer made the rare find using the Near-Infrared Coronagraphic Imager, or NICI, on the international 8-meter Gemini-South Telescope in Chile.

Found: Jupiter-sized Brown Dwarf, Hiding in a Tight Orbit Around a Young Sun
July 30, 2010 - Discover Magazine (blog)
... Astronomers have just found such a duo: a star about the mass of our sun with an unusually close brown dwarf companion.
...
A paper to appear in Astrophysical Journal Letters details the find, which was made using images from the Near-Infrared Coronagraphic Imager, on the Gemini-South telescope in Chile. The researchers predicted the orbit by using two observations, one in April of 2009 and another in May of 2010 and then calculated the brown dwarf’s motion using a computer model.

Brown dwarf in tight orbit around young Sun-like star
July 30, 2010 - AstronomyNow
...
Using the Near-Infrared Coronagraphic Imager (NICI) on the eight-metre Gemini-South Telescope in Chile, an international team of astronomers made a rare find: a very young brown dwarf in orbit around a 12 million year old Sun-like star, around 160 light years away. The star is so young that the astronomers say it still sports a belt of cold circumstellar gas.

First photo of a planet circling distant sun outside our own solar system
June 30, 2010 - Daily Mail
A planet outside our solar system is orbiting another star, astronomers have finally confirmed.
...
Now they have used hi-tech adaptive optics technology on the ground-based Gemini telescope in Hawaii to carry out more detailed measurements which prove the planet is orbiting a distant sun.
