N63A: Supernova Remnant in Visible and X-ray
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.
Featured here is a combined image of N63A in the
X-ray from the
Chandra Space Telescope and in
visible light by
Hubble. The prominent knot of gas and dust on the upper right -- informally dubbed the
Firefox -- is very bright in visible light, while the
larger supernova remnant shines most brightly in X-rays.
N63A spans over 25
light years and lies about 150,000 light years away toward the southern
constellation of
Dorado.
