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 ...
Valhalla is the largest multi-ring basin on Callisto and in the Solar System (with diameter up to 3,800 km). [4] It was discovered by the Voyager probes in 1979–80 and is located on the leading hemisphere of Callisto, in its Jupiter facing quadrant slightly to the north of the equator (at about 18°N latitude and 57°W longitude).
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 ...
NASA's Cassini spacecraft sent back images looking over the shoulder of Saturn's rings. See more on Saturn's rings: No telescope on this planet would ever have been able to see this.
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

The diamond ring effect is visible during this year's total solar eclipse. Thomas Roell/Getty Images The year 2024 had major space events including a total solar eclipse and historic moon landing.
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 ...
