Greenwich 2007: a space odyssey

A £15 million project to replace the planetarium at the Greenwich Observatory is launched today.

The new planetarium, to be built to the northwest of the existing one, will enable the observatory's expert astronomers to provide a more exciting experience for visitors.

TV presenter Peter Snow, who led a fundraising appeal for the project, said: "We are inviting everyone to take part in one of the most adventurous undertakings in the 330-year history of the Royal Observatory. Our ambition is to create a spectacular new environment in which more people can appreciate the wonders of space."

Astronomer Royal Sir Martin Rees said: "The new observatory will bring the excitement of contemporary astrophysics to the UK's oldest astronomical institution."

The official reopening of the observatory is planned for spring 2007.
