     <title>Hubble telescope breaks record for farthest supernova</title>
   	 <description>(Phys.org) —The supernova, designated SN UDS10Wil, belongs to a special class of exploding stars known as Type Ia supernovae. These bright beacons are prized by astronomers because they can be used as a yardstick for measuring cosmic distances, thereby yielding clues to the nature of dark energy, the mysterious force accelerating the rate of expansion of the Universe.</description>

     <title>Can dark energy be explained by symmetrons?</title>
   	 <description>(Phys.org)—A field that permeates the universe and gives rise to a new force, or &quot;fifth force,&quot; between massive objects may be a candidate for dark energy and an explanation for why the expansion of the universe is accelerating. This field, called the symmetron field, is so named because it has a symmetry in regions of high density, while in regions of low density, such as a vacuum, the symmetry is broken and the field mediates the new force.</description>

     <title>Physicists looking to test theory of 'cosmic domain walls'</title>
   	 <description>(Phys.org)—An international team of physics researchers is looking to add credence to a theory that might help explain the nature of dark matter and dark energy – using magnetometers placed strategically around the globe. As they describe in their paper published in Physical Review Letters, the aim is to measure the energy in the walls of theoretic domains that control both dark matter and dark energy.</description>

     <title>The farthest supernova yet for measuring cosmic history</title>
   	 <description>In 2004 the Supernova Cosmology Project based at Lawrence Berkeley National Laboratory used the Hubble Space Telescope to find a tantalizing supernova that appeared to be almost 10 billion light-years distant. But researchers had to wait years until a new camera was installed on the Hubble before they could confirm the spectrum and light curve of supernova SCP-0401—the supernova furthest back in time useful for precise measures of the expansion history of the universe.</description>

     <title>How do you know if you ran through a wall? Testing the nature of dark energy and dark matter</title>
   	 <description>(Phys.org)—Researchers from Canada, California, and Poland have devised a straightforward way to test an intriguing idea about the nature of dark energy and dark matter. A global array of atomic magnetometers – small laboratory devices that can sense minute changes in magnetic fields – could signal when Earth passes through fractures in space known as domain walls. These structures could be the answer to the universe's darkest mysteries.</description>

     <title>New instrument increases Subaru Telescope's field of view sevenfold</title>
   	 <description>The installation of Hyper Suprime-Cam (HSC) onto the Subaru Telescope took place on August 16-17, 2012. The availability of this extraordinary new instrument marks the beginning of a new era in observational astronomy and is a testament to the fruits of international collaboration. The 3-ton, 3-meter (9 feet) high instrument mounted at prime focus contains 116 innovative, highly sensitive CCDs. HSC's 1.5 degree wide field of view (FOV) substantially increases the Subaru Telescope's FOV beyond that available with the present instrument (the Subaru Prime Focus Camera, Suprime-Cam) by seven times.</description>
