description N63A (LMC) Overview
N63A is a supernova remnant in the Large Magellanic Cloud, a satellite galaxy of the Milky Way in the southern constellation Dorado. It is one of the Large Magellanic Cloud's bright X-ray sources and lies within the active star-forming complex N63. The remnant is studied as an example of how a stellar explosion interacts with the surrounding interstellar gas.
help N63A (LMC) FAQ
What is N63A?
N63A is a supernova remnant in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, in the constellation Dorado. It is the expanding debris and shocked gas from the explosion of a massive star.
How old is N63A?
NASA gives an estimated age of roughly 2,000 to 5,000 years. That estimate comes from the remnant's expanding shock and is not a recorded historical supernova date.
Why is N63A bright in X-rays?
Chandra detects gas heated to about 10 million degrees Celsius by the supernova shock wave. N63A is also one of the bright X-ray sources in the Large Magellanic Cloud, making it useful for studying hot plasma and stellar ejecta.
Can N63A be seen in more than one wavelength?
Yes. NASA images combine Chandra X-rays with Hubble optical data and radio observations, revealing different parts of the shock and surrounding material.
