COLDPLAY are going cosmic during their latest album recording sessions.

Frontman CHRIS MARTIN stunned his crew this week by asking them to build him a model solar system in the band's new studio.

I wonder if he's been enjoying TV starman DOCTOR BRIAN COX's recent series as much as I have?

A source said: "Chris likes to create a certain mood when he's in full creative flow.

"He had a real interest in 18th Century revolutionary politics when he was piecing together Viva La Vida. Now he's really got into the universe.

"The crew scratched their heads a little when he first came up with the request but they're cracking away now."
