Science In Action Folgen

Nasa's James Webb Space Telescope has produced amazing images, and amazing science, in its first five months. Roland Pease hears from one of the leading astronomers on the JWST programme, Dr Heidi Hammel, as well as other experts on what they are already learning about the first galaxies in the Universe, the birthplaces of stars, the strange behaviour of some other stars, and the first view of Neptune's rings in over 30 years.Producer: Roland Pease Assistant producer: Sophie Ormiston Image: An image from the James Webb Space Telescope (Credit: Nasa via PA)

Fusion milestone - the science behind the headlines. Laser fusion expert Kate Lancaster walks us through the technology that produced energy gain at the US's National Ignition Facility NIFWhirlwinds on Mars What the sounds of a dust devil passing over NASA's Mars Perseverance Rover tells us about the Martian atmosphere75 years of the transistor electronics revolution - where next for Moore's Law? December 16th 1947 was the day the first ever transistor device passed an electrical current. Trillions are made every day these days, powering our interconnected world. Roland recalls meeting some of the pioneers for the 50th anniversary, including Gordon Moore, and hears from Berkeley Dean of engineering Tsu-Jae King Liu how the revolution will continue for another 25 years.
