PSR J0523−7125

PSR J0523−7125 is a pulsar that, due to its size and brightness, was initially believed to be a distant galaxy.[2] It is located about 160,000 light-years (49,000 parsecs) away in the southern constellation of Dorado, near the center of the Large Magellanic Cloud.[2] Investigation via the Australian Square Kilometre Array Pathfinder showed the pulsar to have a high circular polarization with a steep spectrum.[1] Its rotation measure is twice as large as any other pulsar found in the Large Magellanic Cloud, which also makes it one of the most luminous pulsars ever found.[2]
