Supernovas

At least that's what supercomputers "tell" here astrophysicists for decades. Many of the best computer models that simulate supernova explosions, in fact, the explosion did not produce. Instead, according to the modeling, gravitational forces "were victorious, and the star only experiences a collapse. See title. Sure, physics is something missing. 'Generally speaking, we end up is unclear how the transformation massive stars in supernovae, "- said Fiona Harrison (Fiona Harrison), an astrophysicist at the California Institute of Technology.

– Death of a relatively small star is understandable, but that's for the more massive stars – such mass where more than 9 times the mass of our Sun – is physics of the process is not clear. Something must have been rushing to help out the flow of radiation from the shrinking core and other forces to resist compression, which is due gravity is directed to the central part of the star. To calculate this 'something', scientists need to explore depths of a real supernova during its explosion – not a particularly easy thing! But this is exactly what plans do Harrison, with a new space telescope, which she and her colleagues are developing, and which has been termed nuclear spectroscopic telescope or NuSTAR. After the launch in 2011 aboard the Pegasus launch vehicle (Pegasus), NuSTAR will provide scientists unprecedented picture obtained on the basis of a focused high-energy X-ray radiation coming from supernova remnants, black holes, blazars and other extreme cosmic phenomena. NuSTAR will the first space telescope, which can really focus X-rays are high energy, achieving imaging clarity that is almost 100 times the clarity of images, provided by existing telescopes. .
