  • How to estimate the magnetic field of an exoplanet
    20 November 2014, 8:18 pm
    Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate the value of the magnetic moment of the planet HD 209458b.
  • It's filamentary: How galaxies evolve in the cosmic web
    20 November 2014, 7:34 pm
    How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? Astronomers now propose some answers. The researchers highlight the role of the 'cosmic web' -- a large-scale web-like structure comprised of galaxies -- on the evolution of galaxies that took place in the distant universe, a few billion years after the Big Bang.
  • Riddle of the missing stars: Hubble observations cast further doubt on how globular clusters formed
    20 November 2014, 5:32 pm
    Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations of globular clusters in a small galaxy show they are very similar to those found in the Milky Way, and so must have formed in a similar way.
  • Unravelling the mystery of gamma-ray bursts with kilometer-scale microphones
    20 November 2014, 2:19 pm
    A team of scientists hopes to trace the origins of gamma-ray bursts with the aid of giant space ‘microphones’. It's hoped the kilometer-scale microphones will detect gravitational waves created by black holes, and shed light on the origins of the Universe.
  • Sun's rotating 'magnet' pulls lightning towards UK
    20 November 2014, 2:48 am
    The sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper atmosphere.
  • NASA's Swift mission probes an exotic object: 'Kicked' black hole or mega star?
    19 November 2014, 11:50 pm
    Astronomers have discovered an unusual source of light in a galaxy some 90 million light-years away. The dwarf galaxy Markarian 177 (center) and its unusual source SDSS1133 (blue) lie 90 million light-years away. The galaxies are located in the bowl of the Big Dipper, a well-known star pattern in the constellation Ursa Major.
  • Rosetta continues into its full science phase
    19 November 2014, 7:18 pm
    With the Philae lander's mission complete, Rosetta will now continue its own extraordinary exploration, orbiting Comet 67P/Churymov-Gerasimenko during the coming year as the enigmatic body arcs ever closer to our Sun.
  • Spooky alignment of quasars across billions of light-years
    19 November 2014, 2:45 pm
    New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years. The team has also found that the rotation axes of these quasars tend to be aligned with the vast structures in the cosmic web in which they reside.
  • Geologic maps of Vesta asteroid from NASA's Dawn mission
    18 November 2014, 8:45 pm
    Images from NASA's Dawn Mission have been used to create a series of high-resolution geological maps of the large asteroid Vesta, revealing the variety of surface features in unprecedented detail.
  • Physicists suggest new way to detect dark matter
    18 November 2014, 4:56 pm
    For years physicists have been looking for the universe's elusive dark matter, but so far no one has seen any trace of it. Maybe we are looking in the wrong place? Now physicists propose a new technique to detect dark matter.
