Not just Saturn! Astronomers have found rings around strange, icy worlds on the edge of the Solar System
By Lewis Dartnell| BBC Sky at Night Verified While Saturn is the uncontested Lord of the Rings, it is by no means the only body in the Solar System to host a ring system. The flickering effect of stellar occultation – when a planet passes in front of a background star, briefly blocking it – revealed the presence of rings around Uranus in 1977 and Neptune in 1984. A set of tenuous rings were discovered around Jupiter too, during the Voyager 1 fly-by in 1979.
By Lewis Dartnell| BBC Sky at Night Verified Cosmic rays are high-energy subatomic particles that zip around in outer space. They’re accelerated to enormous speeds by astrophysical events like coronal mass ejections on the Sun or supernovae exploding across the Galaxy. When a cosmic ray encounters planet Earth, it soon hits a gas atom high in the atmosphere, creating a burst of other particles which themselves fly forwards to trigger further interactions, until a huge cone-shaped cascade of different particles develops.
