Before you ask a question:

  • Did you check our Frequently Asked Questions?
  • Do you still have questions about the Sun? About SOHO?
  • If yes, we have established a service so you can ask your question about SOHO or the Sun and a SOHO scientist will respond to your inquiry!

The rules:

  • We will only respond to questions about the Sun and SOHO, and only to those for which answers are not immediately available in other places! Check an astronomy textbook or the web first!
  • Questions contained in the Frequently Asked Questions will be ignored.
  • Don't ask us to do your homework for you! We will not.
  • Questions containing abusive language are ignored.
  • If you are in school, it will help if you can tell us your age and grade level.
  • Make sure your e-mail address is correct and valid. Otherwise, we will not be able to respond to your question.

To use this unique service, send your message to: drsoho [at] esa.nascom.nasa.gov:
