SNR 0519-69.0, 0509-68.7, 0534-69.9, and 0453-68.5: Supernova remnants in the Large Magellanic Cloud galaxy 160,000 light years from Earth. Caption: Chandra's images show expanding shells of gas heated to millions of degrees by shock waves from supernova explosions. Moving in a clockwise direction from the upper left to the lower left, the approximate ages of the remnants are 600 years, 1,500 years, 10,000 years and 13,000 years, respectively. X-ray spectra indicate that the objects on the upper left, upper right and lower right are the remnants of Type Ia supernovas that completely disrupted a white dwarf star. In contrast, the remnant on the lower left was produced by a Type II supernova resulting from the gravitational collapse of a massive star. The explosion left behind a rapidly spinning neutron star that is ejecting a magnetized wind of extremely high-energy particles. This energetic wind appears in the image as the elongated, bright blue-white spot at the center of the remnant. Scale: Image of SNR 0519-69.0 is 1.85 arcmin per side. Image of SNR 0509-68.7 is 2.4 arcmin per side. Image of SNR 0453-68.5 is 8.7 arcmin per side. Image of SNR 0534-69.9 is 8.8 arcmin per side. Chandra X-ray Observatory ACIS Image |
