Far from being solid bullets of rock, many asteroids are fragile clusters of debris that spin so quickly they flirt with self ...

The concept of using rotational force to generate artificial gravity for space habitats has been floating around since NASA called it theoretically viable in the 1960s. Now Japanese researchers hope ...

Every second, the Earth spins at an incredible speed, completing a full rotation in just 24 hours. While this may seem ...

During its initial molten phase, the Moon experienced tidal bulges on its near and far sides due to Earth's immense gravitational pull. The Moon's rotation initially carried these gravitationally ...

Gravity is the weakest of the fundamental forces, but it’s the only force that operates over very long distances. Hence, planets orbit stars, stars form galaxies, and galaxies cluster. Gravity also ...
