This beautiful image from NASA
and in particular the Chandra X-ray Observatory
with optical data included from The Hubble Telescope
. This star exploded and became a supernova a mere 330 years ago in Earth time. Cassiopeia A
is seen in red, green and blue from x-ray data from Chandra and gold from the Hubble telescope. this supernova remnant is located in our Milky way Galaxy
, about 11,000 light years
away. This remnant has a superfluous core that is a neutron star
that is extremely dense and if I remember correctly, if the neutron star continues to become more and more dense than it may indeed surpass it’s ability to remain stable and explode. This is getting beyond my knowledge base and should be researched further.
