As Nasa releases the first images from the James Webb Space Telescope, this film tells the inside story of the telescope's construction and the astronomers taking its first picture of distant stars and galaxies. Will it be the deepest image of our universe ever taken? The successor to Hubble, and 100 times more powerful, the James Webb is the most technically advanced telescope ever built. It will look further back in time than Hubble to an era around 200 million years after the Big Bang, when the first stars and galaxies appeared. Webb's primary mission is to capture the faint light from these objects on the edge of our visible universe so that scientists can learn how they formed, but its instruments are so sensitive it could also be the first telescope to detect signs of life on a distant planet. The James Webb Telescope is an ?8 billion gamble on the skills of its engineering team. It’s the first telescope designed to unfold in space – a complicated two-week operation in which 178 release devices must all work - 107 of them on the telescope's sun shield alone. If just one fails, the expensive telescope could become a giant piece of space junk. From its conception in the late 1980s, the construction of Webb has posed a huge technical challenge. The team must build a mirror six times larger than Hubble’s and construct a vast sun shield the size of a tennis court, fold them up so they fit into an Ariane 5 rocket, then find a way to unfold them in space. This film tells the inside story of the James Webb Space Telescope in the words of the engineers who built it and the astronomers who will use it.

Scientists on the BICEP and Planck missions are attempting to solve a mystery about the earliest moments of our universe, by searching for patterns in the cosmic microwave background. If successful, the missions will help to answer the biggest question anyone can ask: how did our universe begin?

Where and how are we going into space post Space Shuttle? Further travel in space is inhibited by the challenges of gravity wells and the science and cost of developing vehicles that can transcend them. How can the moon possibly help with this problem and move space exploration to the next level?

The largest things in the universe are black holes. In contrast to things like planets or stars they have no physical size limit, and can literally grow endlessly. Although in reality specific things need to happen to create different kinds of black holes, from really tiny ones to the largest single things in the universe. So how do black holes grow and how large is the largest of them all?
