Dance of the Heavyweights (IMAGE) Max-Planck-Gesellschaft Caption Dance of the heavyweights: two neutron stars orbit each other, spiralling ever closer together, radiating gravitational waves in the process. Astrophysicists have long been theorizing that neutron stars, the cores of burnt-out, massive suns, could create gamma rays burst. The image of the real event GW170817 comes from a numerical-relativistic simulation. Credit Numerical Relativity Simulation: T.
