This is the "Ask an Astrophysicist" service of the
Imagine the Universe! web site. We are a small group of volunteers
who work on space-based astronomical observations, including cosmic-ray,
gamma-ray, and X-ray astrophysics. Our research subjects are often exotic,
like black holes, dark matter, and the origin of the universe.

We have already answered many questions, and have an extensive archive
of past questions and answers. Please consult the archive first to see
if your question has already been answered. We attempt to answer as many
questions as possible, but we are a small group of volunteers and cannot
afford the time to answer all the incoming questions.
We will not respond to questions whose answers may be found in our archive or
on our site, or questions unrelated to space-based astrophysics.
- We do not accept more than 1 question per email and no more than
1 question per week from an individual user.
- Educators, please see Special Guidelines
for Teachers.
- It usually takes 1-2 weeks for our volunteers to answer
a question.

Which topic area are you interested in?
(Please select one to search for the answer to your question)
Please note that topic links with
take you to an
archive of questions & answers and other resources, but will not allow you to
submit new questions.
Not sure where your question fits in? If so,
- Read an explanation of these
topic areas.
- Or type a key word or phrase into our
LIBRARY SEARCH ENGINE --- your question
may already have been answered on our site.
If your question does not fall onto one of the above areas,
it means we are not the appropriate resource for your question.
- Check out the "Who are we" page, which explains what we study, what questions we'd most like to answer, and how we fit in with the rest of NASA.
- You can find other similar services by doing a web search for them or you could try doing a general web search for your question --- a lot of the things are on the web, if only you knew where to look. Here is an explanation of how to do a web search.
