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.

JWST could also reveal clues about possible life-supporting planets inside our galaxy. One astronomer who will be eagerly deciphering those clues is Prof Beth Biller, who joined Guardian science editor Ian Sample this week..
