This discovery of a protocluster in the early Universe advances our understanding of how large-scale structures form and how galaxies evolve.

Wed, 29 Dec 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#111221 An international team of astronomers led by Masami Ouchi at the University of Tokyo has discovered a vigorous, star-forming galaxy that existed about 750 million years after the Big Bang. This galaxy, named GN-108036, was a remarkable source of star formation at the so-called "cosmic dawn", a very early time in cosmic history; it was generating an exceptionally large amount of stars in the calm, dark cosmos. Wed, 21 Dec 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#111026 Subaru Telescope has added another dimension of information about one of the most studied of all compact galaxy groups―Stephan's Quintet. Located within the borders of the constellation Pegasus, Stephan's Quintet consists of a visual grouping of five galaxies, four of which form an actual compact group of galaxies; one additional galaxy appears in images of the group but is much closer than the others. Refinements in observations of the quintet are revealing more about its members. A comparison of images compiled by using a suite of specialized filters with Subaru's Prime Focus Camera have shown different types of star-formation activity between the closer galaxy NGC7320 and the more distant galaxies in Stephan's Quintet. They show the quintet in 3-D.

The researchers concluded that another asteroid about 20-50 meters in size impacted Scheila from behind on December 3, 2010 and accounted for its unusual brightness and form. Wed, 19 Oct 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#111011 An international team of astronomers has discovered over two-dozen new free-floating brown dwarfs that reside in two young star clusters. One brown dwarf is a lightweight youngster only about six times heftier than Jupiter. Tue, 11 Oct 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#111005 A research team of astronomers, mainly from Ehime University and Kyoto University in Japan, has successfully detected a carbon emission line (CIVλ1549) in the most distant radio galaxy known so far in the early universe. Using the Faint Object Camera and Spectrograph (FOCAS) on the Subaru Telescope, the team observed the radio galaxy TN J0924-2201, which is 12.5 billion light years away, and was able to measure its chemical composition for the first time.
