Elements in the Aftermath

Massive stars spend their brief lives furiously burning nuclear fuel.
Through fusion at extreme temperatures and densities surrounding the
stellar core, nuclei of light elements like Hydrogen and Helium are
combined to heavier elements like Carbon, Oxygen, etc. in a progression
which ends with Iron. And so a supernova explosion, a massive star's
inevitable and spectacular demise, blasts back into space debris enriched
in heavier elements to be incorporated into other stars and planets (and people!).
This detailed false-color x-ray image from the orbiting Chandra Observatory
shows such a hot, expanding stellar debris cloud about 36 light-years across.
Cataloged as G292.0+1.8, this young supernova remnant in the southern constellation
Centaurus resulted from a massive star which exploded an estimated 1,600 years ago.
Bluish colors highlight filaments of the mulitmillion degree gas which are
exceptionally rich in Oxygen, Neon, and Magnesium. Just below and left of center,
a point like object in the Chandra image suggests that the enriching supernova
also produced a pulsar in its aftermath, a rotating neutron star remnant of the
collapsed stellar core.
