Scientists say interstellar object 3I/ATLAS shows unprecedented chemical and dynamical anomalies, challenging comet formation theories and potentially reshaping space science.

The comet 3I/ATLAS arrived in the solar system with a reputation for being unruly, but its latest trick has stunned even ...

Studying samples from the Bennu asteroid, researchers have found sugars essential for biology, stardust and ... something NASA is calling "space gum?" ...

As the 3I/ATLAS nears its closest distance to Earth, an international team of astronomers now says the space rock may be covered in active, icy cryovolcanoes. If true, the evidence detailed in their ...

Conventionally, the moon is thought to have formed during one big impact, but a three-impact model might make more sense ...

Theia, the world that helped form the Moon, came from the Solar System. Chemical clues in Earth and Moon rocks reveal this close origin.

Roughly four and a half billion years ago the planet Theia slammed into Earth, destroying Theia, melting large fractions of Earth’s mantle and ejecting a huge debris disk that later formed the moon.

It was April 2006, and the mood was celebratory at Napa Valley College. A crowd had assembled to toast the school’s new solar field — 5,600 photovoltaic panels arranged in neat rows across 5 acres of ...
