Wondering About What Seems Incredible.

I am going back out into outer space again for this blog.  I want to talk about pulsars.  I wonder how many of you have heard about pulsars and know what they are?  If you already know everything about them, you can stop reading now, for the rest of you, read on.

A pulsar is a collapsed star that used up its supply of fuel.  When a star has no more fuel left to burn and thus insufficient force to keep the star from collapsing it falls in on itself causing a whopper of an explosion, a supernova.  When this star collapses into a neutron star, it keeps it angular momentum.  That means the smaller it gets the faster it spins.  Pulsars spin really fast.  This is the what is so incredible to me.  They can rotate in less than a second.  The strongest pulsar yet discovered rotates at 0.715 seconds and another pulsar was discovered that revolved once every 1.6 millisecond.  That is 38,500 rpm. . . Wow!!  That is fast for an object that huge.  If it were not so compact, it would tear itself apart.  Talk about compact, the matter in a neutron star is so compact that a piece the size of sugar cube would weigh over 100 million tons on Earth.  No aren't these figures incredible?  But they are true.  Now I bet you all don't feel quite as heavy when compared to neutron stars.  I do hope you have a great day, you hear?
