From the start, the solar system chose fire over ice to build its first bodies
When the solar system first took up the task of building solid bodies—such as planets, moons and protoplanets—it basically had a choice between two ingredients: heat-forged chondrules, which were millimeter-sized bits of ...

Snow, monsoons and oceans shift Earth's center of mass each year, satellite tracking shows
Seasonal changes redistribute enough water around Earth to shift the planet's center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations ...

Could the clues to ancient alien civilizations be hiding in moon dust?
Most of our experience with the Search for Extraterrestrial Intelligence (SETI) has focused on capturing radio signals that alien species have sent out, whether intentionally or unintentionally. That creates a huge "synchronicity" ...

How the 2024 solar superstorm drained Earth's radiation belt
In May 2024, Earth experienced its most intense geomagnetic storm since the Halloween storms of 2003. This "superstorm" filled night skies in many parts of the world with colorful aurorae, and it disrupted some infrastructure, ...

No cities on the moon—there isn't enough water, scientists say
The discovery of water in dark craters at the moon's poles has sparked a "moon rush" to establish bases there, followed by villages, cities and heavy industry. How sustainable is this rush?

Masked tectonic structures suggest Mercury contracted 40% more than its visible scars alone indicate
The surface of Mercury is filled with craters, ridges and steep cliffs. Over billions of years, as the planet's interior cooled, the planet also shrank. Just as the skin of a drying fruit wrinkles when what is inside it shrinks, ...
