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
- It usually takes 1-2 weeks for our volunteers to answer
