On the eve of his 25th anniversary of our favorite telescope Hubble discovered in the constellation Eridanus two amazing explosion of stars, none of the properties that do not fit into conventional astronomers frame. Explosions gone out too fast and were too dim for a supernova, but too bright for the emergence of a new star. The phenomenon was observed twice during 2014, and was presented to the scientific community on April 21.
Flash in the night sky, looking as new bright stars can be caused by different phenomena - the "new star" or "supernova". The first option occurs when a system of two white dwarf stars pulls over matter companion star explodes as a result. Much brighter lights supernova briefly eclipsing the explosion of stars the galaxy, and then gradually died out within a few months. The reasons for the explosion of supernovae can be restart nuclear fusion in stars or extinct gravitational collapse of a massive nucleus.
New phenomenon, discovered the telescope does not fit into any of these schemes. "The combination of properties [Flash] is disconcerting - says Mario Livio, an astrophysicist at the Space Telescope Science Institute (Baltimore). - I thought about the many opportunities, but any of them is not the same with all the characteristics of the observed phenomenon ».
Fixed telescope flash of light came to us from a distance of 7.8 billion light years. It is not clear whether this phenomenon is observed in January and August, the result of the same incident, or were these two different cases.
Steven Rodney, an astronomer at Johns Hopkins University, does not exclude the possibility of observing the so-called kilonovoy - phenomena that occur in the collision of two supermassive objects such as neutron stars or black holes. However, this phenomenon is so rare that watch it twice a year almost unreal. Rodney explained that although so far only conducted a preliminary analysis of the observations, it is possible that astrophysicists have once again change their physical models.
