The blog

Short write-ups of space stories from other outlets. Each one is in our words and links back to where it came from.

How we credit sources

  • We write it ourselves.Every post is our own summary. We do not paste paragraphs from the original.
  • The source is always named.Each post shows who reported it and links to the exact page we read.
  • Quotes and images stay with their owners.We only use them when the source allows it, and we say where they came from.

Image credits for the planets and moons:

  • Planet and moon maps: NASA/JPL (JPL Solar System Simulator maps). We resized them, tinted grey maps, and filled unmapped areas with generated surface.
  • Earth: NASA Blue Marble, used through the three-globe project (MIT licence). Earth clouds and night lights, and the Moon map: example images from the three.js project (MIT licence), based on NASA imagery.
  • The Sun, Venus, Uranus and Titan are drawn by code and are not photographs.
  • Background music: original ambient sound that the page makes live in your browser. It is not a recording and not from any film.
