  • Star Explosion is Lopsided, Finds NASA's NuSTAR (08 May 2015)
    The Nuclear Spectroscopic Telescope Array spacecraft has found evidence that the massive star which created supernova SN 1987A exploded in a lopsided fashion, sending ejected material flying in one direction and the core of the star in the other: the 44 Ti gamma-ray emission lines produced in the innermost ejecta are narrow and redshifted by 700 km/s, according to Boggs et al. (2015, Science, 348, 670).
