So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...

The Moon is slowly receding from Earth at a rate of around 1.5 inches (3.8 centimeters) per year. This might seem infinitesimal when measured against the Moon's average distance from the planet of ...

Imagine a scenario where the Moon, our constant companion in the night sky, begins a deadly trajectory toward Earth. The ...

The ocean on Ganymede may have more water than all the water on Earth. In this artist’s concept, the moon Ganymede orbits the giant planet Jupiter. NASA’s Hubble Space Telescope observed aurorae on ...

A new experiment simulating the surface of Saturn's icy moon Enceladus suggests that the organic compounds found in plumes erupting from its subsurface ocean may actually form on the moon's surface, ...

Explore the surprising discovery of Mimas, Saturn's 'Death Star' moon, which hides a young ocean beneath its surface.

"We know that some microbes on Earth can tolerate the range of pH found on Enceladus." NASA's Cassini spacecraft has flown through the plumes of water vapor spewing out from the ocean inside Saturn's ...

Tides come from a difference in gravity across an object. The force of gravity exerted by the Moon is about 4% stronger on the side of Earth that faces toward the Moon, compared to the opposite side ...
