Extreme Exoplanet-Hunting Telescope to Go Online This Fall

http://www.wired.com/wiredscience/2013/02/extreme-exoplanet-hunter/

February 23, 2013 - Wired.com
The search for exoplanets is about reach the next level with the Gemini Planet Imager, a new smart-car-sized telescope instrument that will use “extreme” adaptive optics to directly see distant planets around other stars.
Most large telescopes on Earth use adaptive optics — mirrors that wiggle a thousand times a second — to compensate for distortion from the atmosphere that causes the familiar “twinkling” effect of stars. With the technology, fuzzy globs of starlight are transformed into sharp pinpoints. GPI will take the method a step farther, using a mirror made from advanced silicon microelectromechanical systems (MEMS) instead of glass.

Event - Orion bullets shot in detail - Seven days: 4–10 January 2013

http://www.nature.com/news/seven-days-4-10-january-2013-1.12160

January 4-10, 2013 - Nature.com
The Gemini South telescope in Chile has been fitted with five lasers and three deformable mirrors, allowing astronomers to correct for atmospheric distortions over an exceptionally large field of view. On 9 January, at a meeting of the American Astronomical Society in Long Beach, California, astronomers unveiled the telescope’s ultra-sharp portrait of the ‘bullets’ of gas seen in the Orion Nebula. In the image, clumps of iron gas (blue) race through the nebula, leaving behind pillars of hot, glowing hydrogen gas (orange).
