LMC N49
Template:Short description Template:Sky Template:Infobox nebula Template:Sister project N49 or LMC N49[1] (PKS 0525-66,[2][1] PKS B0525-661,[1] PKS J0525-6604,[1] SNR J052559-660453[2]), also known as Brasil Nebula,[3] is the brightest supernova remnant in the Large Magellanic Cloud, approximately 160,000 light-years from Earth. Its form has been assessed to be roughly 5,000 years old.[4]
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.[4] A particularly strong gamma-ray burst from LMC N49 was detected on March 5, 1979.[5]
