Children in Perth, Scotland and Perth, Australia have been observing the moon simultaneously in order to establish the similarities and differences when it is viewed from the northern and southern hemispheres.
They also hope to collaborate to calculate how far away it is.
One evening late last month, pupils from North Muirton Primary met online with those who attend Ardross Primary in Perth, Western Australia, to exchange information via a video link over the internet about what they could see in the sky.
The Scottish children got the better end of the deal, with the observation taking place at 6pm in Scotland, while the children in Australia had a sleepover in their school library, waking up at 2am to join in.
Together, they observed the moon through telescopes, took photographs and sketched it. They discovered that, while the northern hemisphere sees "the man in the moon", in the southern hemisphere, he looks decidedly more like a rabbit.
Both schools have been working in conjunction with Martin Hendry of Glasgow University, who designed this project to help celebrate International Year of Astronomy.
