Created by Richard Powell, this stunning educational site presents nine nested maps of the universe, each roughly ten times the scale of the previous, zooming out from the nearest stars to the entire visible universe 14 billion light years away. Multilingual and richly illustrated, it offers a rare sense of cosmic scale that makes abstract astronomical distances genuinely comprehensible.

Created by Josh Worth, this site presents a scale model of the solar system where the Moon is reduced to a single pixel, requiring visitors to scroll endlessly through vast empty space to appreciate the true distances between planets. The experience is both humbling and educational, with witty commentary along the way and the ability to toggle between kilometers, miles, AU, and other quirky units of measurement.
