The Epic Fate of the Sun: Insights from Scientists and Cosmic Graveyards

Scientists have predicted that our Sun will eventually turn into a planetary nebula, a luminous bubble of gas and cosmic dust, after it goes through the red giant phase. This prediction was made using computer modeling and suggests that our Sun, like 90 percent of other stars, will shrink down to become a white dwarf before ending as a planetary nebula. The study also resolved a long-standing conflict between observations and models regarding the brightness of planetary nebulae. However, humans won't be around to witness this cosmic spectacle, as the Sun's increasing brightness will make Earth uninhabitable in about 1 billion years.
