Find out more about the spacecraft Hubble and see images of it in flight. Hubble has made many contributions to science since its launch in 1990. With 10 000 scientific papers attributed to it, Hubble is by some measures the most productive scientific instrument ever built. This section outlines the background to some of the key areas of research Hubble has contributed to.
