Death of the Sun

The video explains the life cycle of stars, focusing on the Sun. Stars, like humans, are born, live, and die. The Sun will eventually become a red giant, expanding significantly and potentially engulfing the inner planets. As the Sun ages, its heat will increase, rendering Earth lifeless long before the Sun exhausts its nuclear fuel. Eventually, the Sun will shrink into a white dwarf, leaving behind a cold, dim remnant. The remaining planets will orbit this small, dense object, marking the Sun's transition into a dead star.
