Web12 nov 2009 · One of the great successes of nuclear astrophysics was demonstrating that the light curves of both thermonuclear (Type Ia) and, at least for late times, core collapse (Type Ib/c, Type II) supernovae (SNe) are powered by the decay of radionuclides synthesized in the explosion. Web1 ora fa · Nine metres long and two metres wide, the mysterious corridor was first detected in 2016 thanks to muon imaging. Muon imaging is a non-invasive technique which uses cosmic ray particles, called muons, to see inside solid objects, detecting changes in density and composition, and therefore enabling scientists to create 3D models of their interiors.
