Hubble telescope delivers stunning 30th birthday picture

It's 30 years ago to the day that the Hubble telescope was launched - and to celebrate its birthday, the veteran observatory has produced another astonishing image of the cosmos.

There's a quiet confidence that Hubble can keep working well into the 2020s. Its supposed "successor" - the James Webb Space Telescope (JWST) - is due for launch next year, but the presence in orbit of this more modern observatory will in truth merely just extend capability; it won't make Hubble redundant.
