Radio 4 Tonight..

[Greg]

9pm. The New Galileos

"First of two programmes in which Andrew Luck-Baker meets today's telescope builders and astronomers.

He meets the scientists behind the James Webb Space Telescope, the gigantic successor to the Hubble Telescope. From 2013, its mission will be to find the first stars born at the dawn of the universe. It will have by far the largest mirror on a space telescope, some 6.5 metres across. It needs to sit behind a giant sunshield, which covers the area of a tennis court, so that it can chill to the temperature of deep space."
