For centuries, astronomers faced the challenge of classifying objects in space based on their appearance. When observing an ...

Climate change is slowing Earth's rotation at record speeds, causing GPS timing errors and navigation delays on your ...

For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive ...

Distinguishing between brown dwarfs and giant planets has confused astronomers, but a clear separating factor has finally been identified.

Context. As a star evolves, the planet orbits change with time due to tidal interactions, stellar mass losses, friction and gravitational drag forces, mass accretion and evaporation on/by the planet.

Earth’s rotation is speeding up. This summer, our planet will spin faster than usual, creating the shortest day since records began. Though we cannot sense these changes, they show the forces that ...

Spin separates giant planets from 'failed stars' Clearest evidence yet that giant planets spin faster than their cosmic lookalikes. (Nanowerk News) Astronomers have ...

Humanity has spent thousands of years understanding billion of years of universal history. Here’s a dizzying look at why the cosmos spin the way they do. *For the why behind this “rotation ...

Somewhere deep below Saturn s cloud tops, the planet rotates at a constant speed. Determining this interior period of rotation has proven extremely complicated. Now, with new Cassini results, a team ...

Venus spins slowly, yet its upper atmosphere races around the planet at roughly 220 miles per hour, a supercharged jet stream that has puzzled scientists for decades. Now a new line of research argues ...

Earth’s gravity has a lot to do with what people think is up and what is down. Things fall down toward the ground, but that direction depends on where you are.
