The internal, infernal machinations of our planet may be way more complex than we suspected. A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation ...

We have all been taught in school that planets revolve in the same direction as the Earth, i.e., in the counterclockwise ...

University of North Carolina researchers have recently discovered a baby exoplanet that could challenge our current understanding of how planets form in newly-minted solar systems. Designated IRAS ...

Scientists announced Monday that Earth is rotating slightly faster than normal, resulting in what is expected to become the second-shortest day ever recorded since precise atomic timekeeping began.

In theory, a planet may be able to orbit a binary star system in a figure of eight, but it may not be particularly stable, ...

The classical picture of star and planet formation suggests that a star’s rotational axis and the orbital planes of its planets should be aligned. However, exoplanetary systems have considerable ...

In a real-life twist on Star Wars' Tatooine—a harsh desert planet with twin suns and a criminal underbelly—astronomers have found a bizarre new world that orbits two stars at a perfect right angle.

Two studies funded by NASA have concluded that Earth’s rotation is slowing due to Earth’s melting polar ice caps. This adjustment in planetary mass is enough to change the rotation as added water to ...

Thanks to NASA's Cassini spacecraft which has been orbiting Saturn since 2004, scientists have been able to observe for the first time ever the seasonal atmospheric circulation direction change on ...

The Planetary Orbit Clock could sit on your desk for days, even years, even lifetimes before you realized the clock’s very simple logic: it’s read from overhead. Working like the original clock (the ...
