New space telescope's vision under threat

Cost cuts likely to dim space telescope's vision

The James Webb telescope, one of NASA's biggest science projects and
Hubble's successor, is $1 billion over-budget - now many involved
want to reduce its observing power.

The curtailed capability would result from polishing the telescope's

astronomers are concerned that the cuts could "jeopardise optical
space astronomy in the next decade".
