(Phys.org) —These delicate wisps of gas make up an object known as SNR B0519-69.0, or SNR 0519 for short. The thin, blood-red shells are actually the remnants from when an unstable progenitor star exploded violently as a supernova around 600 years ago. There are several types of supernovae, but for SNR 0519 the star that exploded is known to have been a white dwarf star—a Sun-like star in the final stages of its life. http://phys.org/news286812372.html Space & Earth Fri, 03 May 2013 15:06:23 EST news286812372 (Phys.org) —Researchers at the Antarctic research station IceCube are reporting that they've detected the highest ever energy neutrinos ever observed. In their paper they've uploaded to the preprint server arXiv, the team describes how in analyzing sensor data over the period 2010 to 2012 they found evidence of two neutrino induced events that were on an order of ten times the energy of any previous event. http://phys.org/news286182974.html Physics Fri, 26 Apr 2013 08:16:50 EST news286182974 Astronomers have observed a binary star that potentially weighed 300 to 400 solar masses at birth. The present day total mass of the two stars is between 200 and 300 times that of the Sun, depending on its evolutionary stage, which possibly makes it the most massive binary star known to date. The results of this study, which was led by astronomer Hugues Sana of the University of Amsterdam and bachelor student Tayo van Boeckel, have been published in Monthly Notices of the Royal Astronomical Society Letters. http://phys.org/news285414717.html Space & Earth Wed, 17 Apr 2013 10:52:14 EST news285414717 (Phys.org) —The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Even though it is a small, or so-called dwarf galaxy, the SMC is so bright that it is visible to the unaided eye from the Southern Hemisphere and near the equator. Many navigators, including Ferdinand Magellan who lends his name to the SMC, used it to help find their way across the oceans. http://phys.org/news284205280.html Space & Earth Wed, 03 Apr 2013 10:54:46 EST news284205280 A team of astronomers led by the International Centre for Radio Astronomy Research (ICRAR) have succeeded in observing the death throws of a giant star in unprecedented detail. http://phys.org/news284037006.html Space & Earth Tue, 02 Apr 2013 00:00:06 EST news284037006 A team of astronomers including Carnegie's Ian Thompson have managed to improve the measurement of the distance to our nearest neighbor galaxy and, in the process, refine an astronomical calculation that helps measure the expansion of the universe. Their work is published March 7 by Nature. http://phys.org/news281795884.html Space & Earth Wed, 06 Mar 2013 13:00:01 EST news281795884 (Phys.org)—Gravity remains the dominant force on large astronomical scales, but when it comes to stars in young star clusters the dynamics in these crowded environments cannot be simply explained by the pull of gravity. http://phys.org/news280597632.html Space & Earth Wed, 20 Feb 2013 15:47:24 EST news280597632 (Phys.org)—This composite image shows the superbubble DEM L50 (a.k.a. N186) located in the Large Magellanic Cloud about 160,000 light years from Earth. Superbubbles are found in regions where massive stars have formed in the last few million years. The massive stars produce intense radiation, expel matter at high speeds, and race through their evolution to explode as supernovas . The winds and supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. http://phys.org/news278617233.html Space & Earth Mon, 28 Jan 2013 17:40:48 EST news278617233 (Phys.org)—Nearly 200 000 light-years from Earth, the Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space, in a long and slow dance around our galaxy. Vast clouds of gas within it slowly collapse to form new stars. In turn, these light up the gas clouds in a riot of colours, visible in this image from the NASA/ESA Hubble Space Telescope. http://phys.org/news277642677.html Space & Earth Thu, 17 Jan 2013 10:58:13 EST news277642677 One of the closest galaxies to the Milky Way almost got away with theft. However, new simulations convicted the Large Magellanic Cloud (LMC) of stealing stars from its neighbor, the Small Magellanic Cloud (SMC). And the crucial evidence came from surveys looking for something entirely different - dark objects on the outskirts of the Milky Way. http://phys.org/news270807482.html Space & Earth Tue, 30 Oct 2012 10:40:01 EST news270807482 (Phys.org)—The first direct detection of radioactive titanium associated with supernova remnant 1987A has been made by ESA's Integral space observatory.

Despite their incredible luminosity, these exotic objects, located in the giant star cluster R136 in the nearby galaxy the Large Magellanic Cloud; have oddly so far been found nowhere else. Now a group of astronomers at the University of Bonn have a new explanation: the ultramassive stars were created from the merger of lighter stars in tight binary systems. The team present their results in the journal Monthly Notices of the Royal Astronomical Society. http://phys.org/news263562101.html Space & Earth Tue, 07 Aug 2012 12:42:26 EST news263562101 (Phys.org) -- Relatively few galaxies possess the sweeping, luminous spiral arms or brightly glowing center of our home galaxy the Milky Way. In fact, most of the Universe's galaxies look like small, amorphous clouds of vapor. One of these galaxies is DDO 82, captured here in an image from the NASA/ESA Hubble Space Telescope. Though tiny compared to the Milky Way, such dwarf galaxies still contain between a few million and a few billion stars. http://phys.org/news260432495.html Space & Earth Mon, 02 Jul 2012 07:21:44 EST news260432495 (Phys.org) -- These bright stars shining through what looks like a haze in the night sky are part of a young stellar grouping in one of the largest known star formation regions of the Large Magellanic Cloud (LMC), a dwarf satellite galaxy of the Milky Way.
