Explanation:
Driven
by the explosion of a massive star,
supernova remnant Puppis A is blasting into the
surrounding interstellar medium about 7,000 light-years away.
At that distance,
this remarkable
false-color exploration of its complex expansion
is about 180 light-years wide.
It is based on the most
complete X-ray data
set so far from the Chandra and XMM/Newton observations,
and infrared data from the Spitzer Space Telescope.
In blue hues, the filamentary X-ray glow is
from gas heated by the supernova's
shock wave,
while the infrared emission shown in red and green is
from warm dust.
The bright pastel tones trace the regions where shocked
gas and warmed dust mingle.
Light from the initial supernova itself, triggered by
the collapse of the massive
star's core, would have reached
Earth about 3,700 years ago, though the Puppis A supernova
remnant remains a strong source in
the X-ray sky.
