A newly analyzed gravitational-wave event has revealed something unexpected about one of the Universe’s most violent encounters. Scientists have found the first strong evidence that a black hole and a ...

How does a planet’s size influence its orbit around its parent star? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of ...

The eight planets in our solar system (yes, it's still weird for me to write "eight," too) orbit the sun in roughly circular paths, although they're ever-so-slightly ellipses instead of circles. A new ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

How do black holes and neutron stars get closer before merging? Their orbits were until now assumed to be circular, with a spiraling approach before the final contact. A recent observation ...

Hot Jupiters, the blisteringly close cousins of our own Jupiter, were once treated as cosmic misfits. Now their orbital patterns are turning into a kind of forensic record, revealing how these giants ...

EVANSTON, Ill. — Except for the fact that we call it home, for centuries astronomers didn’t have any particular reason to believe that our solar system was anything special in the universe. But, ...
