Astronomers using planet-hunting satellites have discovered a rare solar system with six planets moving completely in sync with one another, as if they were untouched by any outside force since being ...

A newly developed model defines the upper limit to the strength of planetary magnetic fields. The model can help better ...

Astronomers studying a faint red dwarf star called LHS 1903 have found a four-planet system arranged in a sequence that no standard model of planet formation predicted. The system follows a ...

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 ...
