Universe

The Universe is all of space and time (spacetime) and its contents, which includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space and all matter and energy. While the size of the entire Universe is still unknown, it is possible to measure the observable universe. Halpern and Tomasello calculated the observable universe using data from European Space Agency's Planck satellite, estimating it to be 90.68 billion light-years across, 0.7% smaller then previously thought.
