Thank the moon for Earth’s lengthening day

For anyone who has ever wished there were more hours in the day, geoscientists have some good news: Days on Earth are getting longer. A...

Magma ocean may be responsible for the moon’s early magnetic field

Around four billion years ago, the Moon had a magnetic field that was about as strong as Earth's magnetic field is today. How the...

Do moon phases produce big earthquakes?

Huge earthquakes are not significantly influenced by the moon, a new study says. The study, conducted by U.S. Geological Survey seismologist Susan Hough, looked at...

Collisions after moon formation remodeled early Earth

Southwest Research Institute scientists recently modeled the protracted period of bombardment following the Moon's formation, when leftover planetesimals pounded the Earth. Based on these...

Moon’s crust underwent resurfacing after forming from magma ocean

The Earth's Moon had a rough start in life. Formed from a chunk of the Earth that was lopped off during a planetary collision,...

How a young-looking lunar volcano hides its true age

While orbiting the Moon in 1971, the crew of Apollo 15 photographed a strange geological feature -- a bumpy, D-shaped depression about two miles...

More Earth-like than moon-like

Mars' mantle may be more complicated than previously thought. In a new study published today in the Nature-affiliated journal Scientific Reports, researchers at LSU...

Drawn from the Deep: Earth’s Primordial Reservoir Older Than the Moon

Earth's mantle -- the layer between the crust and the outer core -- is home to a primordial soup even older than the moon....

Research helps explain formation of ringed crater on the Moon

The Moon’s Orientale basin is an archetype of “multi-ring” basins found throughout the solar system. New research reveals how those rings were formed. Using data...

Scientists’ finding supports moon creation hypothesis

A layer of iron and other elements deep underground is the evidence scientists have long been seeking to support the hypothesis that the moon...

Moon is proto-Earth’s mantle, relocated

Measurements of an element in Earth and Moon rocks have just disproved the leading hypotheses for the origin of the Moon. Tiny differences in the...

Cataclysm at Meteor Crater: Crystal sheds light on Earth, moon, Mars

In molten sandstone extracted by prospectors a century ago, an international team of scientists has discovered microscopic crystals telling of unimaginable pressures and temperatures...

Close encounters of a tidal kind could lead to cracks on...

A new model developed by University of Rochester researchers could offer a new explanation as to how cracks on icy moons, such as Pluto's...

Squeezing out mountains, mathematically, on Jupiter’s moon Io

Mountains aren't the first thing that hit you when you look at images of Jupiter's innermost moon, Io. But once you absorb the fact...

The moon thought to play a major role in maintaining Earth’s...

The Earth's magnetic field permanently protects us from the charged particles and radiation that originate in the sun. This shield is produced by the...

Earth’s moon wandered off axis billions of years ago

A new study published today in Nature reports discovery of a rare event -- that Earth's moon slowly moved from its original axis roughly...

Moon was produced by a head-on collision between Earth and a...

The moon was formed by a violent, head-on collision between the early Earth and a "planetary embryo" called Theia approximately 100 million years after...

Interior Water Not Ruled Out for Our Moon

Scientists have long wondered if water lurks beneath the Moon’s surface. Many thought the scalding impact that formed the Moon long ago would have...

Chinese rover analyzes moon rocks: First new ‘ground truth’ in 40...

In 2013, Chang'e-3, an unmanned lunar mission, touched down on the northern part of the Imbrium basin, one of the most prominent of the...

Study questions dates for cataclysms on early moon, Earth

Phenomenally durable crystals called zircons are used to date some of the earliest and most dramatic cataclysms of the solar system. One is the...
