About SpacesWeb.info

SpacesWeb.info is a discovery platform that brings space-related websites and online resources together in one place. Our goal is simple: make the spaces web easy to explore for everyone.

What can you find here?

Explore astronomy websites, space agencies, missions, observatories, scientific databases, educational platforms, space tools, planetary resources, astrophysics resources and space news — organized into curated categories.

Smart Search

Our search system queries multiple open sources at once, including the SpacesWeb directory, Wikipedia, Wikidata and NASA. Every result is scored by a relevance algorithm that analyzes keyword matches, phrase accuracy, source quality and freshness, so the most relevant results appear first — not always the same order, not always the same source.

Completely Free

SpacesWeb.info is free to use. No paywalls, no accounts, no tracking walls. Open space knowledge should be accessible to everyone.
