Scientists have gotten a never-before-seen look at an area around a large exoplanet 625 light-years away where moons like the one orbiting Earth could potentially form. "Moons likely outnumber planets ...

Astronomers have a new theory about planetary formation, and it revolves around one mysterious concept: interstellar visitors. No, not little green men, but rather deep-space wanderers like the ...
