This illustration reveals a vast disk of gas surrounding the Wolf-Rayet star Nasty 1, shown at center. A close companion star is pulling gas from the star, shown by the bridge of bright material connecting the two stars. This act of celestial cannibalism exposes the massive star’s hot, helium core. Some of the material, however, is escaping into space, forming the huge disk. This disk structure has never been seen before around a Wolf-Rayet star. Image credit: NASA / ESA / G. Bacon, STScI.

An image from a simulation in which a Type Ia supernova explodes, as shown in brown. The supernova material is ejected outward at a velocity of about 10,000 km per second and slams into its companion star, as shown in light blue. The collision produces an UV pulse, which is emitted from the conical hole carved out by the companion star. Image credit: Dan Kasen, University of California Berkeley.
