(PhysOrg.com) -- Astronomers have discovered large galaxies some two thirds of the way back in time to the big bang. This surprising find casts doubt on theories of how the biggest galaxies form. http://www.physorg.com/news157910471.html Space & Earth Thu, 02 Apr 2009 17:01:40 EST news157910471 Over the past 19 years Hubble has taken dozens of exotic pictures of galaxies going "bump in the night" as they collide with each other and have a variety of close encounters of the galactic kind. Just when you thought these interactions couldn't look any stranger, this image of a trio of galaxies, called Arp 194, looks as if of the galaxies has sprung a leak. The bright blue streamer is really a stretched spiral arm full of newborn blue stars. This typically happens when two galaxies interact and gravitationally tug at each other gravitationally. http://www.physorg.com/news159546382.html Space & Earth Tue, 21 Apr 2009 15:26:52 EST news159546382 (PhysOrg.com) -- A huge galaxy neighbouring our own Milky Way appears to have expanded by "digesting" smaller galaxies nearby, a new study has shown. http://www.physorg.com/news171121640.html Space & Earth Wed, 02 Sep 2009 14:49:12 EST news171121640 This beautiful image gives a new look at Stephan's Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth. The curved, light blue ridge running down the center of the image shows X-ray data from the Chandra X-ray Observatory. http://www.physorg.com/news166371617.html Space & Earth Thu, 09 Jul 2009 15:21:24 EST news166371617 A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest that they may have formed relatively recently. This would run counter to the widely-held belief that massive, luminous galaxies (like our own Milky Way Galaxy) began their formation and evolution shortly after the Big Bang, some 13 billion years ago. Further research into the nature of these objects could open new windows into the study of the origin and early evolution of galaxies. http://www.physorg.com/news158585134.html Space & Earth Fri, 10 Apr 2009 12:26:04 EST news158585134 A team of astronomers has discovered a group of rare galaxies called the "Green Peas" with the help of citizen scientists working through an online project called Galaxy Zoo. The finding could lend unique insights into how galaxies form stars in the early universe. http://www.physorg.com/news167921680.html Space & Earth Mon, 27 Jul 2009 14:30:04 EST news167921680 A new Hubble image highlights striking swirling dust lanes and glittering globular clusters in oddball galaxy NGC 7049. http://www.physorg.com/news158329219.html Space & Earth Tue, 07 Apr 2009 13:20:46 EST news158329219 An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies. http://www.physorg.com/news165601534.html Space & Earth Tue, 30 Jun 2009 17:26:07 EST news165601534 In the new ESO image, Barnard's Galaxy glows beneath a sea of foreground stars in the direction of the constellation of Sagittarius (the Archer). At the relatively close distance of about 1.6 million light-years, Barnard's Galaxy is a member of the Local Group, the archipelago of galaxies that includes our home, the Milky Way. The nickname of NGC 6822 comes from its discoverer, the American astronomer Edward Emerson Barnard, who first spied this visually elusive cosmic islet using a 125-millimetre aperture refractor in 1884. http://www.physorg.com/news174718249.html Space & Earth Wed, 14 Oct 2009 05:52:04 EST news174718249 (PhysOrg.com) -- Bursts of star making in a galaxy have been compared to a Fourth of July fireworks display: They occur at a fast and furious pace, lighting up a region for a short time before winking out. http://www.physorg.com/news160318098.html Space & Earth Thu, 30 Apr 2009 13:48:50 EST news160318098 (PhysOrg.com) -- A survey by the Chandra X-ray observatory has revealed in detail, for the first time, the effects of a shock wave blasted through a galaxy by powerful jets of plasma emanating from a supermassive black hole at the galactic core. The observations of Centaurus A, the nearest galaxy that contains these jets, have enabled astronomers to revise dramatically their picture of how jets affect the galaxies in which they live. The results will be presented on Wednesday 22nd April at the European Week of Astronomy and Space Science in Hatfield by Dr Judith Croston of the University of Hertfordshire. http://www.physorg.com/news159636527.html Space & Earth Wed, 22 Apr 2009 16:29:53 EST news159636527 (PhysOrg.com) -- Ram pressure is the drag force that results when something moves through a fluid -- much like the wind you feel in your face when bicycling, even on a still day -- and occurs in this context as galaxies orbiting about the centre of the cluster move through the intra-cluster medium, which then sweeps out gas from within the galaxies. http://www.physorg.com/news173529292.html Space & Earth Wed, 30 Sep 2009 11:36:07 EST news173529292 (PhysOrg.com) -- Using a special camera known as AzTEC developed by a research team led by Grant Wilson, astronomy professor at the University of Massachusetts Amherst, an international research group has imaged a set of ultra-massive galaxies that are thought to form the backbone of a super large structure, or collection of galaxies congregated together, in the very early universe. http://www.physorg.com/news162059711.html Space & Earth Wed, 20 May 2009 17:35:44 EST news162059711 The "coming of age" of galaxies and black holes has been pinpointed, thanks to new data from NASA's Chandra X-ray Observatory and other telescopes. This discovery helps resolve the true nature of gigantic blobs of gas observed around very young galaxies. http://www.physorg.com/news165071424.html Space & Earth Wed, 24 Jun 2009 14:11:01 EST news165071424 (PhysOrg.com) -- A new study seeking to answer the question of why some galaxies are extremely dark compared with others may eventually help to explain the formation of all galaxies, according to researchers at the Harvard-Smithsonian Center for Astrophysics (CfA). http://www.physorg.com/news173715065.html Space & Earth Fri, 02 Oct 2009 15:11:40 EST news173715065
