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.

Proof of least massive planet known to orbit Sun-like star at great distance
July 1, 2010 - Examiner.com
A newly discovered planet that's about eight times the mass of Jupiter has been confirmed to be orbiting its parent Sun-like star from a distance 300 times farther than Earth is from our Sun.
The planet is the least massive planet known to date to orbit its star at such a great distance. It was first discovered in September 2008 by using Gemini Observatory's high-resolution adaptive optics technology.

The adaptive optics system at the Gemini Observatory in Hawaii snapped this photo in the infrared part of the light spectrum. It shows a hot, large Jupiter-like planet near a smallish sun-like star. It was actually found two years ago, but astronomers couldn't be sure they were really looking at a planetary system and not some lucky alignment of objects. Now they're sure.

Scientists find planet with sun-like star
June 29, 2010 - UPI.com
Canadian researchers say they have confirmed a planet discovered outside our solar system is orbiting a star much like the sun.
First observed by the twin Gemini telescopes operating in Hawaii and Chile in April 2008, it required further research to confirm the two objects were associated and not just aligned by chance, a University of Montreal release Tuesday said.

First Direct Photo of Alien Planet Finally Confirmed
June 29, 2010 - Space.com
A planet outside of our solar system, said to be the first ever directly photographed by telescopes on Earth, has been officially confirmed to be orbiting a sun-like star, according to follow-up observations.
...
The new observations that confirm the planet circles its parent star were made using high-resolution adaptive optics technology at the Gemini Observatory. The observatory is an international collaboration with two identical 8-meter telescopes, located at Mauna Kea, Hawaii and Cerro Pachon in northern Chile.

"First" Picture of Planet Orbiting Sunlike Star Confirmed
June 30, 2010 - National Geographic
Two years after making the claim, a team of astronomers says it holds bragging rights to releasing the first ever direct picture of an alien planet orbiting a sunlike star.

Unveiled in September 2008, a picture from the Gemini North telescope in Hawaii shows a direct view of a star system dubbed 1RXS 1609. At the time, astronomers didn't have enough data to say for sure that the bright dot near the star was in fact an orbiting world and not just an object in a chance alignment, as seen from Earth.

First Directly Imaged Planet Confirmed Orbiting Sun-Like Star
June 30, 2010 - Astrobiology
A planet only about eight times the mass of Jupiter has been confirmed orbiting a sun-like star at over 300 times farther from the star than the Earth is from our Sun. The newly confirmed planet is the least massive planet known to orbit at such a great distance from its host star. The discovery utilized high-resolution adaptive optics technology at the Gemini Observatory to take direct images and spectra of the planet.

First directly imaged planet confirmed
June 30, 2010 - AstronomyNow
First reported in 2008, an exoplanet system discovered orbiting a Sun-like star via direct imaging has been confirmed to host an eight Jupiter-mass planet orbiting its star over 300 times farther than Earth is from our Sun.

Its searing temperature is in fact the only reason astronomers could see the planet in the first place. It's also why they decided to point the giant Gemini telescope, located atop Hawaii's Mauna Kea, at the Upper Scorpius Association. What sounds vaguely like a British football team is actually a nursery of young stars, and the scientists concentrated on 85 of the Upper Scorpius newborns...
