- Subject: Introduction
-
- sci.astro is a newsgroup devoted to the discussion of the science of
- astronomy. As such its content ranges from the Earth to the farthest
- reaches of the Universe.
-
- However, certain questions tend to appear fairly regularly. This
- document attempts to summarize answers to these questions.
-
- This document is posted on the first and third Wednesdays of each
- month to the newsgroups sci.astro and sci.astro.seti. It is available
- via anonymous ftp from
- <URL:ftp://rtfm.mit.edu/pub/usenet/news.answers/astronomy/faq/>, and
- it is on the World Wide Web at
- <URL:http://sciastro.astronomy.net/sci.astro.html> and
- <URL:http://www.faqs.org/faqs/astronomy/faq/>. A partial list of
- worldwide mirrors (both ftp and Web) is maintained at
- <URL:http://sciastro.astronomy.net/mirrors.html>. (As a general note,
- many other FAQs are also available from
- <URL:ftp://rtfm.mit.edu/pub/usenet/news.answers/>.)
