Pictures: Behind the scenes at Newsround HQ

Take a peak behind the scenes at Newsround's new Salford home in this brand new photo gallery.
In the morning, Joe and John are talking about the day's stories.

When Newsround is on air, the programme is run from the gallery. The presenters wear earpieces so the producer and director can talk to them. After the programme, we all talk about how it's gone and prepare for the next day.

Our new office in Salford has big windows. We used to work in a basement, so everyone's really happy about this.

And here's Ricky doing something similar. Our HQ is by the side of the Manchester Ship Canal, which connects Manchester to Liverpool and the sea.

Before the programme, Ricky and Leah take time to discuss scripts.

And it's not just girls who have to wear make up.

When this light is on, everyone knows that Newsround is broadcasting and they shouldn't make lots of noise or rush into the studio.

When everything is recorded, it has to be cut up and assembled - or edited - to make the reports you see on the bulletins. Here, Ricky is hard at work in an edit suite.
