Astronomers used the James Webb Space Telescope to study a dust belt around a star named Fomalhaut, which is far away from our solar system. They discovered three rings of dust, much bigger than the distance between the Earth and the Sun. Unlike previous telescopes, the Webb telescope revealed two inner rings that were not visible before. These inner rings suggest the presence of unseen planets that influence the shape of the dust belts, similar to Jupiter and Neptune in our solar system. Fomalhaut’s outer belt is even larger than our own Kuiper Belt.

The dust belts likely formed from collisions between asteroids and comets. By studying the patterns in these rings, scientists can gain insights into the structure of planetary systems. Combining data from the Webb telescope and other telescopes helps us understand how debris belts form around stars. The astronomers also observed a collision in the outer ring and a disappearing feature, indicating additional collisions that left behind only dust.
