Astronomy & Earth

Global weather rendered as a living particle field on a globe you can spin — wind, ocean currents, temperature, particulates, all from real forecast data updated through the day.

Fly through the actual solar system on real ephemeris data, follow live spacecraft along their trajectories, or watch Earth's climate variables as a spinning globe. The positions are not decorative — they are the real ones.

A planetarium in the browser: set a location and a date and get the sky exactly as it appears, with constellations, planets and deep-sky objects identified. Wind time forward to watch the year turn.

Scroll outward from an astronaut to the observable universe, one object at a time. A single idea executed well, and the rest of neal.fun is worth the detour.
