Tidal Acceleration

Planetary scientists at the University of Arizona say they have discovered an entirely new type of cosmic collision.

A physicist, a chemist and a mathematician walk into a bar. It sounds like the start of a bad joke, but in my case, it was the start of an idea that could reshape how scientists think about the history of the Moon. The three of us were all interested in the Moon, but from different perspectives: As...

A new study from NASA's JPL and ETH Zurich says that climate change is slowing Earth's rotation.

Measurements of sulphur isotopes in Io's atmosphere show that the moon may have been volcanically active for its entire lifetime

The ocean's twice-daily rise and fall is only the most obvious effect of tides—they slow Earth's spin and shape stars and galaxies, too

The best-yet map of active volcanoes on Jupiter's moon Io hints at a hidden magma ocean—and more

Let's go explore it.

Jupiter's moon, Europa, is slightly smaller than Earth's Moon and is one of the most promising places to search for alien life.

Inspired by the Milankovitch cycles that play a role in Earth's climate over time, new research at Florida Tech examines how these recurring orbital movements may affect the climate of exoplanets.

The mysterious Planet Nine may have up to 20 moons that could be superheated by the hypothetical planet's gravitational pull, making them easy to spot.

The closest supermoon of the year will be on July 13, 2022. On that date, the moon will lie 222,089 miles (357,418 km) from Earth. The post Closest supermoon of 2022 on July 13 first appeared on EarthSky.

The moon may be older than some scientists thought, according to a new study. It suggests that rock samples from the Apollo missions date back to a melting event, not to the moon's formation.

We have been adding "leap seconds" to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?

Researchers used more than 120 years of data to decipher how melting ice, dwindling groundwater, and rising seas are nudging the planet's spin axis and

The unique properties of sub-Neptunes are linked to to musical rhythmic orbits in space, revealing new insights into planetary formation and resonance systems.

For some reason, when we talk about the age of stars, galaxies, and the Universe, we use "years" to measure time. Can we do better?

Mystery silica ejected in huge quantities from Saturn's icy moon Enceladus is powerful new evidence pointing to heat vents on the floor of a global ocean.

The hidden planet is possibly lurking in our solar system, just waiting to be discovered.
