The first asteroid belt ever seen outside the solar system is more complex than expected, astronomers found, using observations by the James Webb Space Telescope. Looking at the warm dust around a ...

Indeed, our own solar system's asteroid belt is considered to be a "failed planet" of sorts; there are multiple small spherical bodies that make up the asteroid belt, including Ceres, Vesta, and ...
