The universe began about 13.8 billion years ago with the Big Bang. Imagine everything in the universe squeezed into a tiny point, then BOOM, it exploded and started expanding. Now, it’s filled with billions of galaxies, each containing millions of stars, planets, and clouds of gas. There’s also invisible stuff called dark matter and dark energy, which make up most of the universe. Scientists are still uncovering its many mysteries.
Exciting discoveries are helping us learn more. Gravitational waves, ripples in spacetime caused by events like black hole collisions have been detected. The James Webb Space Telescope is capturing amazing images of faraway galaxies and giving us clues about the early universe. Astronomers are also searching for signs of alien life, hoping to answer the big question, Are we alone.
The universe is vast and always changing, and there’s so much more to explore and understand.
