    The scientists found that the farthest

    supernova 100 light-years from earth

    SNLS - 06 d4eu supernova in 4 billion years after the birth of the universe, scientists believe that such a supernova almost every may occur only once in 10000

    cases of supernova event

    According to media reports, the scientists found that recorded the brightest and the most distant supernovae events, about 100 light-years from the us, the outbreak of brightness is 100 times more than ordinary supernova explosions at present, the project results, published in the December 20 issue of the astrophysical

    journal.Distance between supernovae and its host galaxies, but cannot be clearly observed in the figure resolution both.Scientists believe that the newly discovered this supernova located in billions of years after the birth of the universe, the findings clearly particularly puzzling, because we now know most of the supernova from stars and other celestial bodies, so bright and so on need more quality.

    Lars hole galbraith observatory telescope network of the world's scientists Andrew d. howell is the research paper's first author, he thought at first did not know that the object is a special supernovae, even if its for a supernova or if they are within the Milky Way not sure, but it shows a highly unusual light, etc., means that the object has experienced strong energy release, if we release energy calculation according to it, almost no one guessed this is distant supernovae of the universe, and researchers believe that this is not possible.In fact, however, the object is a newly discovered a supernova, Numbers for SNLS - 06 d4eu, is the most distant supernova explosion event.

    Scientists think SNLS - 06 d4eu supernova at the same time, it is likely to be the brightest object in extremely bright supernovae, but also belongs to a branch under the extremely bright supernovae, such a supernova in photometric greatly without hydrogen line, belong to the Ic in the SN type I supernova, the new study also found that supernova explosion is associated with magnetic field model of the original stars, extreme spinning neutron star rotation rate can reach hundreds of times per second, as early as 2009 years, scientists have found a few very bright supernovae, however, it is believed that the magnetar is a possible source of these supernovae, and Andrew d. howell and his colleagues for the first time through the model look the supernova explosion.

    Addition - Hawaiian telescope and the very large telescope array, Gemini, keck telescope are involved in the study of a supernova, scientists from the supernova explosion of ultraviolet ray can calculate the cosmic expansion rate, because when the supernova explosion is only around 4 billion - year - old age of the universe.Extremely bright supernovae are rare, almost every 10000 cases may occur only once, in a supernova event if the supernova in the early universe, it is as good as the research object.
