Rampaging Supernova Remnant N63A

Explanation: What has this supernova left behind? As little as 2,000 years ago, light from a massive stellar explosion in the Large Magellanic Cloud (LMC) first reached planet Earth. The LMC is a close galactic neighbor of our Milky Way Galaxy and the rampaging explosion front is now seen moving out - destroying or displacing ambient gas clouds while leaving behind relatively dense knots of gas and dust. What remains is one of the largest supernova remnants in the LMC : N63A. Many of the surviving dense knots have been themselves compressed and may further contract to form new stars. Some of the resulting stars may then explode in a supernova, continuing the cycle. Pictured above is a close-up of one of the largest remaining knots of dust and gas in N63A taken by the orbiting Hubble Space Telescope . N63A spans over 25 light years and lies about 150,000 light years away toward the southern constellation of Dorado .
