When I was a kid I consumed “NASA Facts”, a public relations newspaper sent out to promote NASA and their achievements. For nostalgia reasons, I wish I hadn’t thrown them all away. Meantime, NASA now has computers and the internet to do the same things. See this link where there is a supurb animation of an exploding star (with a poor planet near by), resulting in a pulsar with a surrounding disk of rubble. The Hubble telescope has seen these same structures.
