Nasa unveils Hubble’s successor

jwst 2007 model

The model of the JWST is on display in Washington DC. The US space agency Nasa has unveiled a model of a space telescope that scientists say will be able to see to the farthest reaches of the Universe. The James Webb Space Telescope (JWST) is intended to replace the aging Hubble telescope. It will be larger than its predecessor, sit farther from Earth and have a giant mirror to enable it to see more. Officials said the JWST – named after a former Nasa administrator – was on course for a launch in June 2013.
