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 ...

Computer simulations have revealed a plausible explanation for a phenomenon that has puzzled astronomers: Rather than occupying orbits at regular distances from a star, giant gas planets similar to ...

Scientists have long puzzled over why all of the planets in Earth’s solar system have slightly slanted orbits around the sun. But a new, Yale-led study suggests this phenomenon may not be so unusual ...

UNDATED (WKRC) - Astronomers recently made an important discovery when they found a rare "in-sync" solar system with six planets all moving in one big grand harmony, completely untouched by outside ...
