The following story covers research into Pulsars and the data from NASA's Chandra X-ray Observatory. I hope others find it as informative as I have........ http://www.sciencealert.com/scienti...coded-the-strange-signals-coming-from-pulsars Scientists might have finally decoded the strange signals coming from pulsars The answer's in the cloud. Astronomers studying pulsars may have finally unravelled why these mysterious pulsating objects appear to send different kinds of signals into space – by tracking the immense cloud trails of their nebulae. Thanks to images taken by NASA's Chandra X-ray Observatory, a new analysis of two very contrasting pulsars shows that pulsars' energy emissions may only be visible to Earth from certain angles – which could explain a mystery that's puzzled scientists up until now. more at.................... http://www.sciencealert.com/scienti...coded-the-strange-signals-coming-from-pulsars from the link: Please Register or Log in to view the hidden image!
