The Little Books of Gaia

Rate this resource

Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way. The spacecraft will provide the positions and velocity measurements of around 1 billion stars – which is about one percent of the stars in our galaxy.

The Little Books of Gaia are A4-page-size summaries that cover different aspects of the Gaia mission which can be folded into little booklets. There is also a template to cut out and build a 3-D model of Gaia.

The six booklets are:

Tales of the Universe - An introduction to astronomy.

History of astrometry - What is astrometry? Why do we want to measure the distances to the stars? What techniques have astronomers used for this?

The galaxy in which we live - How Gaia will revolutionise our understanding of astronomy and, in particular, how it will reveal the origin and evolution of our Milky Way galaxy.

A 3-D tour of our galaxy - A three-dimensional journey to well-known stars and clusters in our galaxy.

Everything you ever wanted to know about Gaia! - An answer to all those questions about Gaia that you wanted to ask.

The search for planets - Gaia will find enormous numbers of other planets outside our Solar System. This booklet explains how.
