Although only privileging our very limited point of view, changes in the skies, even though expected and with rational explanations, like the phases of the Moon, eclipses and occultations, can still inspire strike with awe and reverence and drive us to herald, especially in the waning and vanishing, their return. Clive Thompson directs our attention to one upcoming astronomical event, beginning in March and lasting through November, when the rings of Saturn will disappear. This temporary loss of the gas giant’s main feature, a constellation of debris, failed moons, captured comets and asteroids, occurs for earthly watchers twice every twenty-nine and a half years as the planet makes its revolution around the sun and its inclination puts our world in the ring plane, too thin to be seen head on.
Galileo who began making careful observations of the planet in 1610 one day noticed that the “handles” or “ears” had gone away and was deeply unsettled by this sudden change in the eternal heavens, thinking perhaps the Titan had actually devoured his offspring as in myth. Named after the Roman god of wealth and agriculture who sired Jupiter (Zeus)—Saturn’s patronage did not only extend the harvest but also its cyclical nature, identified with Cronos, whom after overthrowing his own father, Uranus, to become king of the gods was prophesied to be unseated himself by his own children and so gobbled them all up to prevent this from coming to pass. His mother Rhea substituted a boulder for her sixth child, Zeus, and hid him away in Crete to stop the madness. The somewhat more benign Father Time is sometimes portrayed with a sickle or scythe, rising from these same mythopoeic origins, but is nonetheless an equally unmoving standard bearer for the unrelenting march of time and witnessing such an exception, especially for the first time and to see them return months later as Galileo did—the title, as was the practise among astronomers at the time, refers to an anagram that he recorded to document a finding before it was ready for publication, Altissimum planetam tergeminum observavi (I have observed the most distant planet and it has a triple form) and Huygens in the 1650s, correctly identifying the nature of the unusual tripartite form wrote in a letter to his father “aaaaaaacccccdeeeeeghiiiiiiillllmmnnnnnnnnnooooppqrrstttttuuuu,” deciphered as Annulo cingitur, tenui, plano, nusquam coherente, ad eclipticam inclinato or Saturn “is surrounded by a thin, flat ring nowhere touching and inclined toward the ecliptic plane”—is a reflection not only on aging and dissolution but also on recurrence and renewal.
