This stunning visualisation of Cassiopeia A, the result of an explosion approximately 330 years ago, uses X-ray data from Chandra, infrared data from Spitzer and pre-existing optical data from NOAO's 4-m telescope at Kitt Peak and the Michigan-Dartmouth-MIT 2.4-m telescope. The neutron star left over from the stellar blast is an artist's illustration (Courtesy NASA/CXC/D Berry; Model: NASA/CXC/MIT/T Delaney et al.)

You're just summarizing what you have read from the books and observed. It's better if you just damn tell what you have in knowledge that you thought of on your own.
Pretty close, Sttevann. A star larger than about 5 solr masses will end as a nova when it's fuel runs out. Left in the center is a neutron star. An neutron star is a pulsar when it rapidly rotates. The sun will first expand as a red giant, then slowly shrink into a white dwarf. It will slowly cool until it emits no light thereafter.

iv watched a documentary about theese things, ok, so they saied when a rly big star dies, it explodes in a super nova, but when a smaller star dies (like our sun) it end up as a pulsar (or blue dwarf), so how dose a pulsar (blue dwarf) die??? The didnt mention theat -.-
