Scientists have a good understanding of the laws that make our universe tick. But they still don’t quite know how it began — or will end.
The spacecraft’s intentional crash into an asteroid changed the space rock’s orbit by more than 30 minutes — far more than expected.
The hypothetical moon is being called Chrysalis. It could have helped tip the planet over before getting shredded to form Saturn’s rings.
This mission could provide a blueprint for how to deflect a killer asteroid, if one is ever found headed for Earth.
The habitable zone is the region around a star where temperatures could be right for worlds to host liquid water.
Volcanic eruptions billions of years ago may have produced several temporary atmospheres on the moon that held water vapor.
This “dirty snowball” in space is about twice as wide as Rhode Island and darker than coal.
A new cache of confirmed exoplanet discoveries marks a milestone in planets found beyond our solar system.
A handful of rules can describe the route some object repeatedly takes around another in space. Calculating that path, however, can be quite complex.
