PSR J0523−7125 is a pulsar that, due to its size and brightness, was initially believed to be a distant galaxy. 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. Investigation via the Australian Square Kilometre Array Pathfinder showed the pulsar to have a high circular polarization with a steep spectrum. 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.
