Star’s Death Reveals Something New 

New results from the NASA NuSTAR telescope show that a supernova close to our galaxy experienced a single-sided explosion.

A team of scientists including Lawrence Livermore National Laboratory researchers found that X-ray emissions taken with the Nuclear Spectroscopic Telescope Array (NuSTAR) show that the Supernova 1987A explosion was highly asymmetric. The results appear in the May 8 edition of the journal, Science.

This image shows the remnant of Supernova 1987A seen in light of very different wavelengths. Data (in red) show newly formed dust in the center of the remnant. Data in green and blue show where the expanding shock wave is colliding with a ring of material around the supernova. This ring was initially lit up by the ultraviolet flash from the original explosion, but over the past few years the ring material has brightened considerably as it collides with the expanding shockwave.
