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.
Juno project manager underlined the success of the mission to enter Jupiter's orbit by ripping up Nasa's prepared media explainer sheet in case things had gone wrong.
Rick Nybakken tore up the "contingency communications strategy” to cheers at the press conference.
"Juno sang," he told the audience. "And it was a song of perfection."
The headline figures from a historic moment for astronomy as the Juno space probe arrives to orbit around Jupiter after a five-year voyage.
