A new image released today reveals how Gemini Observatory's most
advanced adaptive optics (AO) system will help astronomers study the
universe with an unprecedented level of clarity and detail by removing
distortions due to the Earth's atmosphere. The photo, featuring an area
on the outskirts of the famous Orion Nebula, illustrates the
instrument's significant advancements over previous-generation AO
systems.

January 9, 2013 - Nature News
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...

Using the Gemini North telescope on Mauna Kea, Hawaii, a team of astronomers from the University of Hawaii’s Institute for Astronomy (IfA) have confirmed that the chance of asteroid 2011 AG5 impacting Earth in 2040 is no longer a significant risk -- prompting a collective sigh-of-relief. Previously, scientists estimated that the risk of this 140-meter-diameter (about the length of two American football fields) asteroid colliding with the Earth was as high as one in 500.

"Comet Hergenrother is
splitting apart," said Rachel Stevenson, a post-doctoral fellow working
at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Using the
National Optical Astronomy Observatory's Gemini North Telescope on top
of Mauna Kea, Hawaii, we have resolved that the nucleus of the comet has
separated into at least four distinct pieces resulting in a large
increase in dust material in its coma."
