All In Time

A red hot planetary nebula ejection of nearly one-half solar masses blows off what was once a F3-V star of 1.23 solar mass. Asymmetries in the nebula scatter blue light. The new white hot (300,000 K) planet-sized (0.012 solar radii) white dwarf radiates greater luminosity (although mostly in the high ultraviolet) than when it was a main sequence star. It will slowly cool to 10,000 K and less. The foreground planet shows an undersea station from some past civilization. Most of the planet?s atmosphere and oceans have long since boiled off into space. Its soil has been baked by nearly a billion years of exposure to the star?s two red giant phases. Some of the heavier and cooler nebula gases have been recaptured by the planet and have condensed on its surface. However, the cinder planet is destined to become a deep-frozen fossil. Having been distant enough to survive consumption in its star?s death, its orbit is now expanding from the dispersal of the stellar mass. Its distance originally kept it an ice-covered world during the first half of its star?s six-billion year main sequence lifetime. How many civilizations did the planet spawn? Did any leap to the stars?
