"Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every 'superstar,' every 'supreme leader,' every saint and sinner in the history of our species lived there -- on a mote of dust suspended in a sunbeam."

-Carl Sagan, "Pale Blue Dot," 1994

This image of Earth, captured by NASA's Voyager 1 at a distance of more than 4 billion miles, inspired Carl's famous quote.

From the constellation of Vulpecula.

In 1967, the first pulsar was observed by Jocelyn Bell Burnell and Anthony Hewish. The word pulsar  is a portmanteau of "pulsating star."

Initially dubbed "LGM-1" (a humorous nickname meaning "Little Green Men"), the pulsar emitted radio waves, each separated by 1.33 seconds, which adhered to the conventions of sidereal time. Sidereal time (for example) is a reckoning of the Earth's movement relative to a fixed star. 

Renamed CP 1919 (and with a slew of additional designations to follow), the discovery was soon featured in the massive Cambridge Encyclopedia of Astronomy.  A particular image from that book caught the attention of the English rock band Joy Division in the 1970s. They took the image to graphic designer Peter Saville for a possible album cover adaptation.

Saville described the image as a “comparative path demonstration of frequency from a signal of a pulsar.” Each horizontal line, reaching a series of peaks close to the middle of the graph, was observed data from the Burnell and Hewish pulsar. Shown stacked, the composite image portrayed a "comparative chart of the frequency and the accuracy of this signal.”

So, thanks to a particularly striking data visualization, Joy Division's debut album Unknown Pleasures  contains iconic art (Saville reversed the radio wave image from black-on-white to white-on-black) which likely encouraged purchases without a single note being heard.
