An animation across Saturn's ring plane, looking towards the so-called ring mountains. The ring mountains are strange vertical structures found on the edge of Saturn's B ring. They are not solid, but are rather a constantly changing accumulation of r...

We are a few thousand kilometres from Enceladus, a mid-sized icy moon of Saturn. In 2005, the Cassini spacecraft discovered that this relatively small world - only 500 km across - is, surprisingly, geologically active. Geyser-like jets of water were ...

Astronomers at NOIRLab (Tucson, Arizona, USA) have detected what they believe is the first sighting of the destruction of a gas giant planet caused by the expansion of its ageing red giant star. All sun-like stars expand as their nuclear fuel runs ou...

An impression of the green ice giant planet, Uranus, seen from an ice cave on its innermost substantial moon, Ariel. Uranus is the seventh planet in order of distance from the Sun, orbiting at an average distance of 2.85 billion km. It is unusual in ...

Animation of a flight through the planetary system of Epsilon Eridani. This system is structured somewhat similar to the Solar System, with an outer cloud of comets like the Oort cloud, analogues of the Kuiper- and asteroid belts, and a gas giant pla...

An impression of the green ice giant planet, Uranus, seen from the surface of its innermost substantial moon, the fractured Miranda. Uranus is the seventh planet in order of distance from the Sun, orbiting at an average distance of 2.85 billion km. I...
