Contact Ask an Astronomer

Ever had a question about astronomy you've wanted answering? Ask us!

You can find the answer to many questions which have already been asked on our website at If we've already answered a similar question, you may not get a reply so please check our site first!

Ask an Astronomer is NOT a homework service - we will not answer questions which are clearly for this kind of work!

While we do try to answer as many questions as we can, it may take us a little while to get back to you - we run this as volunteers and we're meant to be doing research full time!

Please note: 'Ask an Astronomer' is for general questions about astronomy which are suitable to be published in the public domain (i.e. on this website). Any questions outside of this remit may be discarded without response.

This question is for testing whether you are a human visitor and to prevent automated spam submissions.
