How Big Is the Universe? The True Scale in Real Space Images

How big is the universe, really? Built from real images from NASA, ESA and the James Webb Space Telescope, we start with Voyager 1, a spacecraft launched in 1977, and keep going: past the planets, past the nearest stars, across the Milky Way and Andromeda, through the cosmic web, all the way to the edge of the observable universe, 93 billion light-years across. The space imagery comes from the NASA, ESA, ESO and Webb archives. A few shots are AI-animated or AI-illustrated, and they're all listed below.

Next film: Timelapse to the End of the Universe. #space #universe #astronomy About this film: narration uses an AI voice. A small number of shots are AI-animated from real space images (several nebulae, an aurora and the space station's solar panels) or are AI-generated illustrations (for example Proxima b's surface, Saturn's rings, a solar flare, the Andromeda collision sky, a person under the Milky Way), and the music was AI-generated. Diagrams and animations are illustrations, not to scale unless stated.
