Medium Rock with Smaller Rock Herding Ring of Tiny Rocks

This illustration shows what the Centaur Chariklo and its rings could look like, based on our current understanding. Credit: NASA, ESA, CSA, Leah Hustak (STScI) In school, we learn all about the eight planets, Pluto, the asteroid belt - and its larger members like OG former planet Ceres - and comets. What your average kids' book omits are the random larger objects that hang out in the middle distances in our solar system. Around Jupiter’s orbit, we have the Trojan asteroids, and out around between Jupiter and Neptune are transition objects called centaurs. Like asteroids, they can be a...

(Big-)Moonless worlds have unstable tilts

Modern-day Mars experiences cyclical changes in climate and, consequently, ice distribution. Unlike Earth, the obliquity (or tilt) of Mars changes substantially on timescales of hundreds of thousands to millions of years. At present day obliquity of about 25-degree...

How Rivers Flow: Here, Mars & Titan

This false-color image shows Titan’s second-largest body of liquid, Ligeia Mare, in the moon’s northern hemisphere. Scientists think that rivers flowing into large bodies of liquids like this one should form deltas. Credit: NASA/JPL-Caltech/ASI/Cornell New research...
