Submission + - NASA unveils Hubble's successor
An anonymous reader writes: NASA has unveiled a model of a space telescope intended to replace the ageing Hubble telescope with the James Webb Space Telescope (JWST).
A full-scale model is being displayed outside the NASA museum in Washington DC.
The $4.5bn (£2.27bn) telescope will be shaded from sunlight by a shield, enabling it to stay cold, increasing its sensitivity to infrared radiation, take up a position some 1.5 million km (930,000 miles) from Earth, and will measure 24m (80ft) long by 12m (40ft) high, and incorporate a hexagonal mirror 6.5m (21.3ft) in diameter, almost three times the size of Hubble's.
