Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

The biggest planet in our Solar System just got a little smaller. Okay, not physically, but our measurements of Jupiter just got more precise, and it turns out there's slightly less of the giant than ...

Jupiter is already the biggest planet by far in our solar system, but new research suggests it was somehow once even larger than it is now. Twice as large, in fact. To put that into context, those ...

The planetary system, located 120 light-years away, features four worlds orbiting a red dwarf star and challenges classical formation schemes.

The fourth planet in the system is a rocky world, while the second and third ones are gas planets.

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

Updated measurements from NASA’s Juno spacecraft could help researchers better understand the planet's mysterious interior, ...

Jupiter, the largest planet in the solar system, isn’t exactly the size and shape scientists believed it was. New measurements from the Juno spacecraft show ...

We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting closer to their stars than Mercury, and rocky worlds much larger than Earth ...
