New study: Ancient magnetic fields may explain the difference between Jupiter's moons and Saturn's moons

  • No comments
Simulations by researchers from Japan and China suggest that Jupiter's strong magnetic field created a void in the disk around it and preserved large moons, while at Saturn a weaker field led to a more sparse system dominated by
Neptune's largest moon, Triton, has an unusual retrograde orbit and is thought to be a captured object from the Kuiper Belt. New research suggests that the long evolution of its orbit may also explain Neptune's axial tilt. (NASA Science)

New study: Triton may have tilted Neptune-Rahab

A new paper suggests that Neptune's unusually large moon, likely captured from the Kuiper Belt and moving in a retrograde orbit, gradually changed the planet's rotational axis, leading to its current tilt.
New models suggest that Pluto and Charon were formed by a giant collision. This composite of enhanced color images of Pluto (lower right) and Charon (upper left) was taken by the New Horizons spacecraft as it passed through the Pluto system in 2015. Pluto and Charon are shown at approximately their relative sizes, but their true separation is not at the correct distance. Credit: NASA/JHUAPL/SwRI

How Pluto and its moon Charon were formed from a giant collision

New research reveals that Pluto and its large moon Charon formed from a unique "kiss and capture" process following a giant collision, with significant implications for understanding the solar system.
