Some claim that Earth is only 6,000 years old. But can physics actually support that idea. Radioactive decay, heat flow, starlight travel time, and orbital mechanics all place strict limits on Earth’s ...

But only in the last 70 years have we known for certain they were there. In 1956, physicists Clyde Cowan and Frederick Reines ...

An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

Research into Jupiter’s moons shows Io and Europa did not evolve apart but formed with opposite compositions from the beginning.

While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor ...

While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor Europa is thought to harbor a vast global ocean of liquid water beneath ...

Scientists say they have found geochemical traces of Earth’s ancient self hidden far below our feet, suggesting that parts of the planet that existed before the Moon-forming collision 4.5 billion ...

The new research demonstrates for the first time that the wave nature of matter persists even at large scales, using massive ...

MicroBooNE's results show no evidence for sterile neutrinos, strengthening support for the standard three-flavor neutrino model and adding complexity to earlier unexplained anomalies.

Together with an international team, researchers from the Molecular Physics Department at the Fritz Haber Institute have ...

The U.S. Environmental Protection Agency has designated January 2026 as National Radon Action Month. The purpose of this designation is to remind residents of Iroquois County of the serious danger ...
