There is a particular quality to the 90s and early 2000s that people who lived through them describe in emotional rather than analytical terms. It felt like something. A specific register of possibility, a sense of before that is hard to articulate except to say it was different.
Astrology has a framework for this. The outer planets (Jupiter, Saturn, Uranus, Neptune, Pluto) move slowly enough that they describe collective conditions rather than personal ones. When Pluto moved through Scorpio from 1983 to 1995, it created a particular set of conditions for the culture: intensity, the surfacing of what had been underground. When Neptune moved through Capricorn and then Aquarius, the spiritual and imaginative register of the era shifted in ways that are legible in the music, the films, the aesthetics.
The decade nostalgia format uses these outer planet positions as the astrological backdrop for close reading of specific cultural artifacts from the era: the songs that defined a summer, the films that caught the feeling of a particular year, the public figures who carried the energy of the collective moment in their personas.
The nostalgia is not random. The pull toward a particular decade tends to be activated in people whose natal charts resonate with the outer planet positions of that era. Those years, in some sense, speak in their language.
Reading an era through its astrology is a way of taking it seriously. The 90s were a specific collective moment with their own astrological signature, and the artifacts from that moment carry that signature.
The pop culture translator handles the close reading of specific artifacts: the album, the film, the TV moment. Aurora carries the atmospheric pieces about the era as a whole. Ren takes the analytical frame: outer planet positions, what those positions typically describe, whether the cultural evidence supports or complicates the interpretation.
Nostalgic in register. Not sentimental. The decades were what they were.
