NASA's Juno spacecraft has successfully entered Jupiter's orbit after completing its five-year, 1.4 billion mile journey from Earth.
The probe will investigate how much oxygen and water the planet holds, and will look beneath the planet's clouds to discover what lies in its core.
The leader of the NASA team behind the successful Juno mission to Jupiter has hailed the team effort behind the project, describing its completion as a "dream come true".
Speaking at a press conference after the space probe began its orbit of the solar system's biggest planet, Scott Bolton said: "NASA did it again. That says it all to me.
"I am so happy to be part of the team that did that. This team has worked so hard and we have just such great people and it's almost like a dream coming true right here."
The headline figures from a historic moment for astronomy as the Juno space probe arrives to orbit around Jupiter after a five-year voyage.
A space probe is just hours away from completing its five-year, 1.4 billion mile journey from Earth, and entering Jupiter's orbit.
