How we write
Last updated
Every fact on this site should be something you can check. This page explains where the information comes from and how each article is put together.
Which sources do we use?
We start with the organizations that do the science and run the missions, because they publish first-hand results:
- NASA, including its science pages, mission pages, skywatching guides and image library.
- The European Space Agency (ESA) and its mission pages.
- Mission and research teams, and the peer-reviewed papers behind a discovery when one is published.
Each article lists the exact pages it used under "Sources," with the date they were checked when that matters.
How do we handle dates and numbers?
Dates, distances and figures are copied from the source and checked again before publishing. When sources give a value in miles and kilometers, we show both. Sky events such as meteor showers are given with the dates the official source lists, and viewing times are described in general terms, because the exact time depends on where you are.
When the science is not settled, we say so. A new study is presented as a new result, not as a final answer.
How is AI used?
AI tools help with research and first drafts. A person, Marcos Salles, reads the sources, checks every fact and edits every article before it goes live. Read more on the About page.
What about headlines?
A headline should tell you what the article is about and match what it says. We don't use teasers that hide the answer, exaggerated claims or fake urgency.
Where do the images come from?
Mostly from NASA's public image library, with the credit under each image. Images from other agencies are used under their license terms and credited. Illustrations are labeled as artist's concepts.
How often are articles updated?
When a source publishes something that changes an article, the article is updated and the "Updated" date at the top changes. We don't change dates for edits that leave the content the same.
Who decides what is covered?
Only the editor. The site may show ads served by Google; advertisers have no say in topics or content, and there are no sponsored articles.
