Astronomers used James Webb to inspect a ringed asteroid and discovered water ice crystals in the rings surrounding it.

have revealed that the spectacular rings surrounding this asteroid are home to water ice, marking an exceptional discovery for astronomers.

Because Webb is so powerful, astronomers were able to use the telescope to inspect the asteroid during a phenomenon known as occultation – when a star or planet moves behind another. In this instance, a star moved behind Chariklo, allowing scientists to analyze what the rings of the asteroid are made of. By doing this, they discovered that those rings contained water ice crystals.

From there, astronomers used Webb’s various instruments to further analyze the asteroid. By doing so, they discovered that the rings of the asteroid are home to crystallized water ice. And, based on the amount of water ice crystallization believed to exist in those rings, astronomers say the asteroid is constantly being bombarded by space dust and micrometeoroids.
