N49 or LMC N49[3] (PKS 0525-66,[1][3] PKS B0525-661,[3] PKS J0525-6604,[3] SNR J052559-660453[1]) is the brightest supernova remnant in the Large Magellanic Cloud, approximately 160,000 light-years from Earth. It has been assessed to be roughly 5,000 years old.[2]
The latest pictures of N49 by the Chandra X-ray Observatory have revealed a bullet-shaped object traveling at about 5 million miles an hour away from a bright X-ray and gamma-ray point source, probably a neutron star with an extremely powerful magnetic field, known as a soft gamma repeater.[2] A particularly strong gamma-ray burst from LMC N49 was detected on March 5, 1979.[4]
