Do you have a question about astronomy or something in the sky or in space? You can try to find an answer to your question in the following ways:
Search all text in these pages (aa.quae.nl) or on the whole web (WWW) by typing the question into the search box below and then pressing the "Google Search" button:
Did you try the things mentioned above but were you yet unable to find the answer to your question? Then you can send your question to me. I'll probably not answer your question if:
Even if your question is new and clear and astronomical and no homework question, it can take a week or longer before you get an answer.
It may be tempting to send your homework assignments to me, but if I suspect that your question is in fact a homework assignment, then I won't just send you the desired answer, because the purpose of homework is that you learn how to find your way through the topic of the homework, and copying my answers won't give you any experience with that. And anyway, I won't sit next to you at the test or examination that you'll receive later about this topic, so you'll have to do the work yourself then, too.
If you have a homework assignment with an astronomical flavor, and you can't figure it out by yourself, then I'm willing to help you along, but only if I can tell that you've seriously tried to complete the assignment by yourself. That means that you'll have to be able to tell me exactly where you got stuck, and which answers you've thought of for the problem, and why you can't decide which one is the correct one. Sort of like your teacher would expect from you.
