The poor old Hubble telescope has had a long old run, and is starting to show the strain. But never fear – NASA is busy working on its replacement, the James Webb Space Telescope (JWST), which is set to launch in 2013. Not only three times the size, the JWST is loaded with technologies that weren’t even possible when the Hubble was put into orbit – which means people like me who are suckers for awesome images of deep space won’t have to do without.
