How Astronomer Jocelyn Bell Burnell Shaped Our Understanding of the Universe by Discovering Pulsars, Only to Be Excluded from the Nobel Prize – Brain Pickings
In July of 1967, the month of her twenty-fourth birthday, Northern Irish astrophysicist Jocelyn Bell Burnell (b. July 15, 1943) discovered the first pulsar. This was landmark evidence that neutron stars — the collapsed core left behind by the final explosion of a dying star, first proposed a year after the discovery of the neutron in 1933 — were real. But the most significant implication of the discovery was that if neutron stars could result from stellar death, so could black holes, which even Einstein considered a neat but limited, purely mathematical, and possibly unprovable theoretical construct.

the "Unknown Pleasures" cover, emulated in Mathematica
In July 1967, astronomers at the Cavendish Laboratory in Cambridge, observed an unidentified radio signal from interstellar space, which flashed periodically every 1.33730 seconds. This object flashed with such regularity that it was accurate enough to be used as a clock and only be off by one part in a hundred million.

It was eventually determined that this was the first discovery of a pulsar, CP-1919.  This is an object that has about the same mass as the Sun, but is the size of the San Francisco Bay at its widest (~20 kilometers) that is rotating so fast that its emitting a beam of light towards Earth like a strobing light house! Pulsars are neutron stars that are formed from the remnants of a massive star when it experiences stellar death.

A hand drawn graph plotted in the style of a waterfall plot, in the Cambridge Encyclopedia of Astronomy, later became renown for its use on the cover of the album "Unknown Pleasures"  by 1970s English band Joy Division.


The entire blog at http://intothecontinuum.tumblr.com/ is pretty great. Lots of nice mathematical animated GIFs, accompanied by Mathematica source and related ponderings.
