Nasa’s new space telescope and its search for extraterrestrial life
On 22 December, if all goes to plan, the £7.5bn James Webb space telescope (JWST) will be blasted into space on top of a giant European Ariane 5 rocket. As it travels to its final destination – a point about a million miles away – it will begin to unfold its gold, honeycombed mirror; a vast light-catching bucket that could give us a view of the universe deeper and more sensitive than we’ve ever had before.
