The beauty and mystery of Saturn’s rings revealed by the Cassini mission

The Cassini space probe took us up close and through the beautiful rings of Saturn. It captured some amazing images, and even the sound of the rings during its mission.
A Cassini portrait of five of Saturn’s moons. Janus (179km across) is on the far left, Pandora (81km across) orbits between the A ring and the thin F ring, Enceladus (504km across) is centre, Rhea (1,528km), is bisected by the right edge of the image and the smaller moon Mimas (396km) is seen beyond Rhea also on the right side of the image.

The PLATO mission: an investigation of planetary systems

While we on Earth are familiar with our own star, the Sun, the European Space Agency's PLATO mission will explore solar systems similar to ours as well as those that are more exotic.

Six mysteries of Jupiter’s Great Red Spot

Juno has flown closer to the solar system's most famous storm than any other spacecraft to take the most detailed images to date. They may help scientists reveal some of the spot's best-kept secrets.

The new space race: why we need a human mission to Mars

We could learn a lot from any mission to send people to Mars, such as whether there's life elsewhere in the universe or even the technology for new household appliances.

Juno mission unveils Jupiter’s complex interior, weather and magnetism

We may need to re-think our models of Jupiter’s formation thanks to the first results from Juno probe orbiting the planet, and new observations from Earth.
