Ask an Astrophysicist (NASA)
https://imagine.gsfc.nasa.gov/ask_astro/index.html
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
There are 21 topics!!

I looked for an archive, but apparently, each topic has its own archive of answered questions.
Some topics are closed to new questions, including "General Astronomy & Astrophysics"
