Space War Editorial Team

Editorial Team

The Space War Editorial Team produces Space War's coverage of military space and defense technology. We report on missile defense and space-based systems, nuclear weapons and arms control, drones and directed-energy weapons, and the great-power competition shaping security beyond Earth. Articles reflect our team's collective editorial process, source verification, drafting, technical review, and editing, rather than a single writer's work. Space War takes editorial responsibility for content under this byline. For more on how we work, see our editorial policy.

The interstellar comet 3I/ATLAS, discovered on July 1, 2025, by a survey telescope in Chile, is now believed by astronomers at Oxford to be roughly 7 billion years old — meaning it was already drifting through the Milky Way for nearly 3 billion years before our solar system even existed — having formed in a part of the galaxy called the thick disk, where the stars are older than almost everything else humanity has ever observed

Seven billion years is the kind of number that stops behaving like time. Our solar system is about 4.6 billion years old.
