The Children of Cookstown High School have been learning how to computer ‘code’ recently - as part of the initiative they have programmed a weather balloon and hope to launch it at the Ballyreagh Industrial Estate, just off the Sandholes Road,  and they’re hoping it’ll reach 100,000 feet into the air. It's the brain child of Cookstown High School teacher Robert Johnson, and we join them live from the launch site.

Poet Cherry Smyth meets Ronan Lundy at her beloved strand in Portstewart, a place that was quite literally her backyard when growing up. Ronan hears why her place is still so important to her, and learns more about her debut novel ‘Hold Still’.

It is published by Holland Park Press.

What does a star sound like? Apparently they almost have their own language, if you listen closely,  like a celestial music box or a starry dawn chorus. Award winning composer Robert is the man behind a new sonic art installation at the Armagh Observatory, and joins us live from Armagh.
