Andromeda Galaxy after 2.1 billion Years:
In about 2.1 billion years, we'll have a spectacular view of Andromeda in the sky, shining even larger than the moon! And then, about 3.1 billion years from now, the Earth might face some challenges as the sun expands and heats up, potentially causing our planet to dry up. It's crazy to think about the vastness of time and the changes our universe goes through.
