The Big Ring is composed of numerous galaxies and galaxy clusters that form a continuous, almost perfect ring-like pattern in space. With its diameter of 1.3 billion light years and a circumference of 4 billion light years, it is one of the largest known structures within the observable universe. The structure is made up of many galaxy clusters ...
J1407b is a substellar object, either a free-floating planet or brown dwarf, with a massive circumplanetary disk or ring system. It was first detected by automated telescopes in 2007 when its disk eclipsed the star V1400 Centauri, causing a series of dimming events for 56 days. The eclipse by J1407b was not discovered until 2010, by Mark Pecaut ...

CAPE CANAVERAL, Fla. (AP) — New research suggests that Saturn’s rings may be older than they look — possibly as old as the planet. Instead of being a youthful 400 million years old as commonly thought, the icy, shimmering rings could be around 4.5 billion years old just like Saturn, a Japanese-led team reported Monday.
Fainter planetary rings can form as a result of meteoroid impacts with moons orbiting around the planet or, in the case of Saturn's E-ring, the ejecta of cryovolcanic material. [6] [7] Ring systems may form around centaurs when they are tidally disrupted in a close encounter (within 0.4 to 0.8 times the Roche limit) with a giant
Researchers have identified the biggest ever solar storm – when the sun emits huge bursts of energy – using ancient tree rings. The event happened 14,300 years ago, according to the analysis ...
The rings have a reddish colour in visible and near-infrared light. The age of the ring system is unknown, possibly dating back to Jupiter's formation. At least 95 moons orbit the planet; the four largest moons—Io, Europa, Ganymede, and Callisto—orbit within the magnetosphere, and were discovered by Galileo Galilei in 1610.
