Scientists observe this process in space for the first time: Something has changed

The ring systems consist of four rings and dispersed material surrounding a small icy body named Chiron, which orbits the Sun in the region between Saturn and Uranus, Reuters reports.Chiron belongs to a class of objects known as centaurs, located in the outer Solar System between Jupiter and Neptune.Both Chiron and other centaurs exhibit characteristics of both asteroids and comets.The body, officially designated (2060) Chiron, has a diameter of about 200 kilometers and takes roughly 50 years to orbit the Sun, while centaurs are generally composed of rock, ice, and complex organic compounds.Since its discovery in 1977, astronomers have observed Chiron periodically, and for years it has been known to be surrounded by some type of material.Scientists obtained the best data on Chiron in 2023, using the telescope at Pico dos Dias Observatory in Brazil, based on which they concluded that Chiron is surrounded by well-defined rings: three dense rings at distances of approximately 273 kilometers, 325 kilometers, and 438 kilometers from Chiron&rsquo;s center, and a fourth ring about 1,400 kilometers from the center.This outer structure, observed for the first time, is unusually far from Chiron, and further observations are needed to confirm its stability as a ring.The three inner rings are embedded in dust that rotates in a disk-like formation.Shutterstock/Artsiom PSignificant changesComparing data from different years, researchers have observed significant changes in the ring system, providing clear evidence that the rings are evolving in real time, said Christian Luciano Pereira, a researcher at the National Observatory in Brazil and the author of a study published in Astrophysical Journal Letters.Pereira stated that Chiron&rsquo;s rings are likely composed mainly of ice mixed with smaller amounts of rock, similar to Saturn&rsquo;s rings.Ice may play a key role in the stability of ring systems, as its physical properties allow particles to remain separate rather than coalescing into a moon.Chiron occasionally exhibits comet-like behavior, ejecting gas and dust into space.In 1993, it even displayed a small tail, similar to what is seen in comets.Scientists believe that Chiron&rsquo;s rings may be remnants of a collision that destroyed a small moon, the result of an impact with space debris, material ejected by Chiron itself, or a combination of all these factors.
