New Discovery: JWST Observes an Asteroid with Rings

James Webb Space Telescope discovers Chariklo, an asteroid with its own Saturn-like rings, marking a major milestone in astronomy and space exploration


Astronomers have just made a remarkable discovery: they’ve spotted an asteroid with its own Saturn-like rings! With the help of the James Webb Space Telescope (JWST), scientists were able to observe this unique and mysterious celestial object, located in the Kuiper belt. This marks a major milestone for astronomy and space exploration.

The asteroid, known as Chariklo, is about 250 kilometres in diameter and orbits the Sun between Saturn and Uranus. Discovered in 1997, it had been classified as a Centaur object — something between an asteroid and comet — but with the help of JWST, scientists were able to make an even more detailed observation.

Using an infrared camera and spectrograph, astronomers were able to determine that Chariklo has two distinct rings composed of dust particles. The outer ring extends approximately 7 kilometres away from the asteroid’s centre and is about 3 kilometres wide. The inner ring is smaller, extending 3 kilometres outwards, but it is much denser than its outer counterpart. The rings around Chariklo are composed mainly of water ice, which is similar to those found around Saturn and other gas giants.

The discovery of Chariklo’s rings could provide insight into how planets form and what kind of structures celestial bodies can have. It may even give us a better understanding of the evolution of our own Solar System.

For now, scientists are continuing to study Chariklo in order to learn more about this unique object and its rings. With the James Webb telescope and other instruments, astronomers are sure to uncover many more fascinating discoveries in the years ahead.

What new mysteries will JWST uncover next? We can’t wait to find out!
