NASA's NuSTAR Telescope Discovers 'Impossible' Ultra-Luminous Pulsar

NASA’s NuSTAR telescope recently discovered an ultra-luminous X-ray source (shown in the pink area in the circle) inside the nearby galaxy M82. This newly-discovered X-ray source was found to be powered by an extremely luminous pulsar, which produces the energy equivalent of 10 million Suns. Image Credit: NASA/JPL-Caltech
