Big Ring. The Big Ring is a ring-shaped large-scale structure formed by galaxies and galaxy clusters near the constellation Boötes with a diameter of 1.3 billion light years, located 9.2 billion light years away. [1] It was discovered in 2024 by Alexia Lopez, a PhD student at the University of Central Lancashire. [2]
The main rings are, working outward from the planet, C, B and A, with the Cassini Division, the largest gap, separating Rings B and A. Several fainter rings were discovered more recently. The D Ring is exceedingly faint and closest to the planet. The narrow F Ring is just outside the A Ring. Beyond that are two far fainter rings named G and E.
A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as gas, dust, meteoroids, planetoids or moonlets and stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as of Saturn, or circumplanetary disks.
The μ ring is the outermost of the pair, and is twice the distance from the planet as the bright η ring. [13] The outer rings differ from the inner narrow rings in a number of respects. They are broad, 17,000 and 3,800 km wide, respectively, and very faint. Their peak normal optical depths are 8.5 × 10 −6 and 5.4 × 10 −6, respectively ...
Quaoar (minor-planet designation: 50000 Quaoar) is a large, ringed dwarf planet in the Kuiper belt, a region of icy planetesimals beyond Neptune. It has an elongated ellipsoidal shape with an average diameter of 1,090 km (680 mi), about half the size of the dwarf planet Pluto.
The main ring was discovered in 1979 by the Voyager 1 space probe [1] and the system was more thoroughly investigated in the 1990s by the Galileo orbiter. [2] The main ring has also been observed by the Hubble Space Telescope and from Earth for several years. [3] Ground-based observation of the rings requires the largest available telescopes. [4]
Rings of Neptune imaged by the James Webb Space Telescope's NIRCam instrument. The rings of Neptune consist primarily of five principal rings.They were first discovered (as "arcs") by simultaneous observations of a stellar occultation on 22 July 1984 by André Brahic's and William B. Hubbard's teams at La Silla Observatory (ESO) and at Cerro Tololo Interamerican Observatory in Chile. [1]
2060 Chiron is a ringed small Solar System body in the outer Solar System, orbiting the Sun between Saturn and Uranus.Discovered in 1977 by Charles Kowal, it was the first-identified member of a new class of objects now known as centaurs—bodies orbiting between the asteroid belt and the Kuiper belt.
