Chandra X-ray Image of N49
N49 is a supernova remnant in the Large Magellanic Cloud. The Chandra X-ray data shows million-degree gas. Although X-rays reveal a round shell of emission, the X-rays also show brightening in the southeast, confirming the idea of colliding material in that area. Chandra also finds evidence for a so-called soft gamma-ray repeater -- mysterious objects that rapidly emit pulses of high-energy radiation -- within the boundary of N49.

Hubble Optical Image of N49
N49 is the brightest supernova remnant in optical light in the Large Magellanic Cloud. The unique filamentary structure seen in the optical data by Hubble has long set N49 apart from other well understood supernova remnants, as most supernova remnants appear roughly circular in visible light. Recent mapping of molecular clouds suggests that this supernova remnant is expanding into a denser region to the southeast, which would cause its asymmetrical appearance.

Spitzer Infrared Image of N49
N49 is a supernova remnant in the Large Magellanic Cloud. Gas at the outer parts of the remnant is seen in the infrared data from Spitzer. While astronomers expected that dust particles were generating most of the infrared emission, the study of this object indicates that much of the infrared is instead generated in heated gas.
