Astronomers measure the speed at which the solar system is hurtling through space by mapping surrounding galaxies and observing how light from other objects is shifted. New measurements, however, put ...

A study of the Beta Pictoris Moving Group (BPMG), a cluster of relatively young stars, suggests a high prevalence (20 out of 30 surveyed) of stars possessing Jupiter-mass planets in long-period orbits ...

A massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says. Interactions with ...

Billions of years ago, a star may have passed incredibly close to our Solar System, triggering a series of cosmic events that led to the creation of the moons around the outer planets and the unusual ...

A six-planet solar system around the star HD110067, a near sun-like star roughly one hundred light years away, has stunned scientists by its rarity. In other words, there are many stars that have ...

A new study suggests that a close encounter with a massive interstellar object, possibly eight times the mass of Jupiter, may have significantly altered the orbits of the four outer planets in our ...

From an early age, we are taught to understand that the planets of our solar system change in position while orbiting a central star, the sun. But does the sun itself move within the solar system?

Far beyond Neptune, at the far outer rim of our Solar System, astronomers have spotted what looks like a hidden “structure” ...

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, ...
