Answers by Expert:
I can answer almost any question about astronomy and related sciences (such as physics and geology). I will not answer questions about astrology and similar pseudo-scientific rubbish.
I have been a professor of astronomy for nearly 40 years, and am working on an online text/encyclopedia of astronomy.
