Infographics (IMAGE) Lomonosov Moscow State University Caption The slowest spinning X-ray pulsar in a globular star cluster has been discovered in the Andromeda galaxy. This object is a small and very dense neutron star pulling gas from a companion star. Infalling gas forms a bright hot spot on the neutron star surface, which creates a light-house effect, because the neutron star revolves every 1.2 seconds. Credit Artwork by A.
