A Neutron Star With A Disc Of Warm Dust. Key Ring

This illustration shows a neutron star (RX J0806.4-4123) with a disc of warm dust that produces an infrared signature as detected by the Hubble Space Telescope. The disc wasn't directly photographed, but one way to explain the data is by hypothesizing a disc structure that could be 18 billion miles across. The disc would be made up of material falling back onto the neutron star after the supernova explosion that created the stellar remnant.
