It is strange that it appears everywhere in reality and now in stars:-http://www.scientificamerican.com/article/strange-stars-pulsate-according-to-the-golden-ratio/?WT.mc_id=SA_SPC_20150212-"Scholars have seen the golden ratio in nautilus shells, the Parthenon, da Vinci paintings and now in stars. A new study of variable stars observed by the Kepler space telescope found four stars that pulsate at frequencies whose ratio is near the irrational number 0.61803398875, known as the Greek letter phi, or the golden ratio (which is also sometimes referred to as the inverse of that number, 1.61803398875…).
 
"The golden ratio had not turned up in the celestial sphere before astronomer John Linder of The College of Wooster in Ohio and his colleagues analyzed the Kepler data."
