Educators & Students

Bring astrophysics to life in the classroom.

Abstract concepts become concrete when students can interact with actual stellar data. Show galaxy evolution by loading a main-sequence star, then a red giant, then a white dwarf all rendered accurately in real time.

  • Visualize the Hertzsprung-Russell diagram with live renders for each star class
  • Compare morphological classes side-by-side see why Rigel is blue and Betelgeuse is red
  • Demonstrate black hole physics without specialized software or hardware
  • Embed the GLEN viewer directly into your course website or LMS

Look up any object you can see tonight.

You see a bright point of light in Orion. With TheGalaxyDB, you can look it up in seconds, see exactly what it looks like physically, and learn everything about it its temperature, distance, mass, and morphological class.

  • Search 33M+ objects by name, constellation, or Bayer designation
  • Filter by magnitude to find what is visible to the naked eye tonight
  • Discover which stars host confirmed exoplanets

REST API
Developers & Researchers

Query 33M+ galaxy objects stars, quasars, exoplanets, and more. Clean JSON. No fuss.

The TheGalaxyDB REST API gives you full access to every object in the catalog. Filter, paginate, sort. Get full physical parameters in one call. Build your own astronomy tools on top of the most comprehensive open stellar database on the web.

  • Filter by morphological class, magnitude, distance, constellation, or type
  • Real ATNF period data for every pulsar in the catalog
  • NASA Exoplanet Archive data included for all exoplanet hosts
  • Consistent JSON schema, versioned endpoints, generous rate limits

Why TheGalaxyDB

The difference is in the rendering.

Most databases give you a table of numbers. TheGalaxyDB gives you the star itself something students can actually see and react to.

The API is genuinely the cleanest stellar data API I have worked with. Schema is consistent, pagination works, and the physical parameters are complete.

We run the Explorer in full-screen mode on two kiosks in our hall of astronomy. Visitors spend more time on those than any other exhibit.
