Pulsars
Pulsars are dense, highly magnetised dead stars that emit radio waves along their magnetic poles. These waves sweep around as the star rotates, a bit like lighthouse beams. Ordinary pulsars spin just a few times per second, but some spin hundreds of times faster. Astronomers suspect that many of these millisecond pulsars are essentially no different from ordinary pulsars, except that their rotation has sped up as they have stripped material from nearby stars.

Re: Pulsars
Did you know;
That when the first pulsar was detected astronomers thought it was a signal from an intelligent lifeform.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Apropos of that, just recently: http://www.theaustralian.news.com.au/story/0,25197,25448647-30417,00.html
