More planets are changing directions. First, Mercury circled retrograde. This week, Mars is reversing course and Neptune starts spinning forward again. Going retrograde and stationing direct are the ...

A newly analyzed planetary system has turned up a world orbiting at such a skewed angle that it defies the neat textbook ...

Shedding light on the gravity of the situation. Most people do not realize that many of the stars and heavenly bodies they see in the sky no longer exist. In fact, many have ceased to exist for ...

An orrery is a moving model of a planetary system. Daniel Fabrycky, University of California at Santa Cruz, created two animated orrerys to display the 1,235 Kepler planet candidates. 1,235 Planet ...

In this work, we extensively investigate the formation of near 4:2:1 mean motion resonances (MMRs) configuration by performing two sets of N-body simulations. We model the eccentricity damping, gas ...

When the lathe begins to spin, time slows, and matter takes on new form. Each rotation mirrors the rhythm of planets in motion. The turner’s hands act like gravitational forces, shaping continents, ...
