The universe is a vast and ever-expanding entity that includes all of space, time, matter, and energy. Comprising billions of galaxies, each with billions of stars, it exhibits a scale that is difficult to comprehend. Celestial bodies like planets orbit stars, with Earth being part of the Milky Way galaxy. The majority of the universe’s mass is attributed to mysterious dark matter, while dark energy propels its accelerated expansion. The Cosmic Microwave Background is a remnant of the Big Bang, marking the universe’s origin. Ongoing exploration by space agencies aims to unravel the cosmos’ mysteries and enhance our understanding of its complexity.
