Why Jupiter Has Four Giant Moons While Saturn Has Just One, Study Explains
Scientists suggest the strong magnetic field of Jupiter created regions for multiple large moons to form, unlike Saturn. The findings could reshape how astronomers search for exomoons in distant planetary systems.

Scientists Discover High-Density Rocky Planet in LHS 1903 System That Defies Conventional Formation Models
ESA’s CHEOPS mission has uncovered a surprising rocky planet at the outer edge of the LHS 1903 system. Located 116 light-years away, the discovery defies expectations that outer planets are gas giants. Scientists say the finding offers rare evidence that planets can form in gas-depleted environments, challenging current planetary formation models...

NASA Juno Mission Uncovers Subtle Geometric Shifts That Challenge Existing Models of the Jovian Interior
Scientists have refined Jupiter’s size and shape using modern radio signal observations, finding the giant planet slightly smaller and more flattened than earlier estimates. Though the difference is only a few kilometres, researchers say it greatly improves models of Jupiter’s interior, gravity, and atmospheric structure, offering deeper insigh...

Unique Inside-Out Planetary System Reveals Unexpected Rocky World on the Outer Edge
Astronomers have discovered a rare inside-out planetary system around LHS 1903, where a rocky planet exists beyond gas giants. Using ESA’s CHEOPS telescope, researchers found evidence that planets formed one after another in a gas-depleted environment, challenging long-standing theories about how planetary systems form and evolve across the galax...
