On Science is called Assassin , which evokes the acronym of the program under which it was discovered, All Sky Automated Survey for Supernovae System .
The research team that failed to reach the sensational discovery is made up of researchers from many different universities (including Italy ) that, under the banner of Ohio, were able to see the world premiere of the presence of the supernova record exploded with a power of 200 times to what normally characterizes phenomena. Next comments have shown a certain similarity with supernovae Super light poor hydrogen; through the eye of 10 meters of the South African Large Telescope be established that is 3.8 billion light years from us.
Few hours ago the famous “ Science “, one of the most prestigious science journals in the world, published a major study on discovery supernova explosion most light that has ever been detected in the history. You need JavaScript enabled to view it.
In the research group, coordinated by the Ohio State University , there are two Puglia: Milena Bufano original of Canosa di Puglia and forces of the National Observatory of Catania astrophysics, and Gianluca Masi , scientific director of the Virtual Telescope of Ceccano native of Acquaviva delle Fonti.
Besides the exceptional brightness supernova ASASSN-15lh has another special sign: is in a Galaxy and relatively large calm while most of the colleagues SLSNe found in small galaxies with intense star formation activity.
Not even the return data for nickel, whose radioactive decay is the ‘engine’ of supernovae ” for a brightness as that achieved in the peak of ASASSN-15lh – noted – would require no less than 30 solar masses of nickel-56. Probably more comments will clarify this point. “
It shines 570 billion of times more than Sun and 20 times more than the Milky Way supernova more light ever, a cosmic cataclysm so gigantic and mysterious. The supernova will be observed Hubble , the most famous space telescope.
The great thing about this supernova is the fact that it is able to emit an energy equal to that who could issue the Sun at this defining moment in about 90 billion years.
