A close-up of Astronaut John Grunsfeld shows the reflection of Astronaut Andrew Feustel, perched on the robotic arm and taking the photo. The pair teamed together on three of the five spacewalks during Servicing Mission 4 in May 2009.

Hubble_ESAThe Hubble Space Telescope is a collaboration between ESA and NASA. It's a long-term, space-based observatory. The observations are carried out in visible, infrared and ultraviolet light. In many ways Hubble has revolutionised modern astronomy, by not only being an efficient tool for making new discoveries, but also by driving astronomical research in general.
