astro22 is run by a small editorial team. We read every message about our astronomy articles — especially corrections.

Report a correction

Astronomy figures change as missions return new data. If you spot a number that is out of date or wrong, email [email protected] with the page URL and the detail. We fix confirmed errors and note the update date on the article.

Questions and suggestions

Want a topic covered, or have a question about something you read? Send it to the same address. We cannot offer personal astronomy tutoring, but reader questions often shape what we write next.

How we work

Every article is checked against primary sources — NASA and ESA mission data, the IAU, and peer-reviewed astronomy journals — before publishing. More about our process is on the about page.
