Overhead

About this site

Everything above us, tracked in real time — here's what that means and how it works.

What Overhead is

Overhead is a single home base for two things worth looking up for: what's happening in space, and what's happening in the sky. Astronautics covers space agency and mission news, upcoming launches, meteor showers, eclipses, the ISS, and a real-time night sky map. Aviation covers airline and aircraft news, airshows, aviation history, and a live flight radar sourced from a public ADS-B feed. There's no account and no tracking beyond what's needed to show you what's above your own location — nearly everything runs directly in your browser. The one exception is a small serverless function that relays Flight Radar's aircraft lookups to their data provider; it doesn't store anything.
