Astronomy enquiries

We regret that the astronomers at the Royal Observatory Greenwich are not able to answer astronomy questions from members of the public via telephone, post or email. Our astronomers are also unable to comment on unsolicited scientific papers or theses. These should be sent to a refereed journal.
