The following paragraphs are from a draft of an essay about the discovery of pulsars.

[1]
In the summer of 1967, Jocelyn Bell Burnell, a postgraduate student at Cambridge University, was analyzing miles of paper chart recordings from a newly constructed radio telescope. The telescope had been designed to study quasars, but Bell Burnell was looking for anything unusual in the massive amounts of data generated.

[2]
To investigate further, she used a high-speed recorder that could capture detail on a much shorter time scale. This faster recording revealed that the signals were actually incredibly regular pulses, occurring every 1.33 seconds.

[3]
Initially, some team members wondered if the signals were artificial transmissions from an extraterrestrial civilization, jokingly naming the source "LGM-1" for "Little Green Men." However, when Bell Burnell located a second, similarly pulsating source in a completely different part of the sky, it became clear that this was a natural, albeit entirely new, astronomical phenomenon: a pulsar.

[4]
While scanning the charts, she noticed a strange "scruff" of signals that did not look like the random interference typical of radio noise. The mysterious signals recurred at the exact same location in the sky, suggesting they originated from deep space rather than a terrestrial transmitter.

For the sake of the logic and cohesion of this essay, where should Paragraph 4 be placed?
