"It highlights how JWST is revolutionizing our understanding of the most distant solar system bodies," Bettati said. The new study was published in February in the journal Icarus.

The Oort cloud is a shell of icy objects that forms the very outskirts of our Solar System. Recently, a group of researchers discovered that the inner portion of the Oort cloud likely has spiral ...

Alpha Centauri, the nearest star system to the sun, is probably shedding comets and asteroids into our solar system — and even producing a few meteors in our sky. Located just 4.3 light-years ...
