(PhysOrg.com) -- University of Exeter, UK, research has added to a growing evidence that several giant planets have orbits so tilted that their orbits can be perpendicular or even backwards relative to their parent star`s rotation. http://www.physorg.com/news180724809.html Space & Earth Tue, 22 Dec 2009 17:20:34 EST news180724809 (PhysOrg.com) -- In 2004, Hubble created the Hubble Ultra Deep Field (HUDF), the deepest visible-light image of the Universe, and now, with its brand-new camera, Hubble is seeing even farther. This image was taken in the same region as the visible HUDF, but is taken at longer wavelengths. http://www.physorg.com/news179489629.html Space & Earth Tue, 08 Dec 2009 10:14:38 EST news179489629 Noted for harbouring Eta Carinae -- one of the wildest and most massive stars in our galaxy -- the impressive Carina Nebula also houses a handful of massive clusters of young stars. The youngest of these stellar families is the Trumpler 14 star cluster, which is less than one million years old -- a blink of an eye in the Universe's history. This large open cluster is located some 8000 light-years away towards the constellation of Carina (the Keel). http://www.physorg.com/news179068963.html Space & Earth Thu, 03 Dec 2009 13:23:15 EST news179068963 (PhysOrg.com) -- Which come first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside? A brand new scenario has emerged from a recent set of outstanding observations of a black hole without a home: black holes may be `building` their own host galaxy. This could be the long-sought missing link to understanding why the masses of black holes are larger in galaxies that contain more stars. http://www.physorg.com/news178804126.html Space & Earth Mon, 30 Nov 2009 11:49:22 EST news178804126 (PhysOrg.com) -- The Orion Nebula is one of the most beautiful sights of the winter night sky, its gas and dust glowing from the intense ultraviolet radiation of a cluster of massive young stars. http://www.physorg.com/news175507575.html Space & Earth Fri, 23 Oct 2009 09:07:12 EST news175507575 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) -- Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the centre of the other, until ultimately, the two merge into one massive galaxy. The object in the image, NGC 2623, is in the late stages of the merging process with the centres of the original galaxy pair now merged into one nucleus. However, stretching out from the centre are two tidal tails of young stars showing that a merger has taken place. During such a collision, the dramatic exchange of mass and gases initiates star formation, seen here in both the tails. http://www.physorg.com/news174649432.html Space & Earth Tue, 13 Oct 2009 11:20:41 EST news174649432 (PhysOrg.com) -- Most stars form in clusters. Recent studies of nearby star forming regions find that about three-quarters of their young stars are located in groups with ten or more members. The formation of stars in clusters is thus a central feature of the study of how stars are made. The presence of the cluster highlights the possible roles of many other physical phenomena in the birth, for example, the effects of the massive amounts of gas always found in young clusters, or the possibly disruptive interactions between embryonic stars in the crowded womb. It has even been suggested that massive stars form from the coalescence of smaller, neighboring stars. http://www.physorg.com/news174588930.html Space & Earth Mon, 12 Oct 2009 17:57:39 EST news174588930 IC348 is a glowing nebula of young stars, hot gas, and cold dust seen in the direction of the constellation of Perseus. It is the nearest rich cluster of young stars to earth, being only about one thousand light-years away. Its proximity has made it an important laboratory for astronomers probing the early stages of stellar evolution and star formation. At an estimated age of only two to three million years, it is also a somewhat young cluster; IC348 did not shine in the night sky of the first hominids. For comparison, our sun is about 4.5 billion years old. http://www.physorg.com/news170083835.html Space & Earth Fri, 21 Aug 2009 14:32:28 EST news170083835 (PhysOrg.com) -- Today ESO has released a new and stunning image of the sky around the Eagle Nebula, a stellar nursery where infant star clusters carve out monster columns of dust and gas. http://www.physorg.com/news166960881.html Space & Earth Thu, 16 Jul 2009 11:01:41 EST news166960881 (PhysOrg.com) -- Using NASA's Spitzer Space Telescope, an international team of astronomers has discovered streams of young stars flowing from their natal cocoons in distant galaxies. These distant rivers of stars provide an answer to one of astronomy's most fundamental puzzles: how do young stars that form clustered together in dense clouds of dust and gas disperse to form the large, smooth distribution seen in the disks of spiral galaxies like the Milky Way? http://www.physorg.com/news160410037.html Space & Earth Fri, 01 May 2009 15:20:59 EST news160410037 (PhysOrg.com) -- NASA's Galaxy Evolution Explorer Mission marks its sixth anniversary studying galaxies beyond our Milky Way through its sensitive ultraviolet telescope, the only such far-ultraviolet detector in space. http://www.physorg.com/news160161119.html Space & Earth Tue, 28 Apr 2009 18:12:47 EST news160161119 (PhysOrg.com) -- Astronomers using the United Kingdom Infrared Telescope (UKIRT) in Hawaii, the IRAM Millimetre-wave Telescope in Spain, and the Spitzer Space Telescope in orbit above the Earth, have completed the most wide-ranging census ever produced of dynamical star formation in and around the well-known Great Nebula of Orion. http://www.physorg.com/news159460527.html Space & Earth Mon, 20 Apr 2009 15:35:59 EST news159460527 (PhysOrg.com) -- Processes that laid the foundation for life on Earth -- star and planet formation and the production of complex organic molecules in interstellar space -- are yielding their secrets to astronomers armed with powerful new research tools, and even better tools soon will be available. Astronomers described three important developments at a symposium on the "Cosmic Cradle of Life" at the annual meeting of the American Association for the Advancement of Science in Chicago, IL. http://www.physorg.com/news153679446.html Space & Earth Thu, 12 Feb 2009 16:45:40 EST news153679446 The planet Jupiter gained weight in a hurry during its infancy. It had to, since the material from which it formed probably disappeared in just a few million years, according to a new study of planet formation around young stars. http://www.physorg.com/news150383252.html Space & Earth Mon, 05 Jan 2009 13:07:32 EST news150383252 (PhysOrg.com) -- Shock waves around dusty, young stars might be creating the raw materials for planets, according to new observations from NASA's Spitzer Space Telescope. http://www.physorg.com/news145639908.html Space & Earth Tue, 11 Nov 2008 15:31:48 EST news145639908 Astronomers have used ESO's Very Large Telescope Interferometer to conduct the first high resolution survey that combines spectroscopy and interferometry on intermediate-mass infant stars. They obtained a very precise view of the processes acting in the discs that feed stars as they form. These mechanisms include material infalling onto the star as well as gas being ejected, probably as a wind from the disc. http://www.physorg.com/news142859152.html Space & Earth Fri, 10 Oct 2008 12:05:52 EST news142859152 This week, Astronomy & Astrophysics is publishing new observations with AMBER/VLTI of the gas component in the vicinity of young stars. An international team of astronomers led by E. Tatulli (Grenoble, France) and S. Kraus (Bonn, Germany) used the unique capability of the VLT near-infrared interferometer, coupled with spectroscopy, to probe the gaseous environment of Herbig Ae/Be stars. These are young stars of intermediate mass (approximately 2 to 10 solar masses), which are still contracting and often show strong line emissions. http://www.physorg.com/news142850513.html Space & Earth Fri, 10 Oct 2008 09:41:53 EST news142850513 (PhysOrg.com) -- University of Toronto astronomers have unveiled what is likely the first picture of a planet around a star similar to the sun. http://www.physorg.com/news140793673.html Space & Earth Tue, 16 Sep 2008 14:21:13 EST news140793673 The mystery of how young stars can form within the deep gravity of black holes has been solved by a team of astrophysicists at the Universities of St Andrews and Edinburgh. http://www.physorg.com/news138626663.html Space & Earth Fri, 22 Aug 2008 12:24:23 EST news138626663
