🔄 Role In Stellar Evolution

Every star changes over time, including Altair! 🔄Altair is currently in the main sequence stage, which is like its middle-age phase. As time goes by, it will start getting older and change into a red giant. 🌟When it does, it will expand and become much bigger—maybe even swallowing nearby planets! 🌍💥 Eventually, Altair will shed its outer layers and leave behind a core—a special remnant known as a white dwarf. Understanding stars like Altair helps scientists know how all stars, including our Sun, evolve throughout their lives! 🌌
