Illustration of a hypothetical rejuvenated planet, a gas giant that has reclaimed an infrared glow. NASA's Spitzer Space Telescope found tentative evidence for one such planet around a dead star, or white dwarf, called PG 0010+280 (white dot). It is proposed that the planet would accumulate some of the material sloughed off by its star as the star was dying. The material would cause the planet to swell in mass and, as material fell onto the planet, it would heat up due to friction and glow with infrared light. The final result would be an old planet, billions of years in age, radiating infrared light as it did in its youth. Spitzer detected an excess infrared light around the white dwarf PG 0010+280.
