Big image captures a billion stars

Scientists have produced a colossal picture of our Milky Way Galaxy, to reveal the detail of a billion stars.

It is built from thousands of individual images acquired by two UK-developed telescopes operating in Hawaii and in Chile.

Archived data from the project, known as the Vista Data Flow System, will be mined by astronomers to make new discoveries about the local cosmos.

Dr Nick Cross from the University of Edinburgh describes the information that went into making the big picture.
