A system of seven Earth-like exoplanets appeared to be unstable. Now their orbits have been rewritten in the music of the spheres.

As physicists extend the 19th-century laws of thermodynamics to the quantum realm, they’re rewriting the relationships among energy, entropy and information.

Angela Olinto’s new balloon experiment takes her one step closer to the unknown source of the most energetic particles in the universe.

After a surprise discovery, astrophysicists are racing to understand superenergetic flashes of radio waves that sometimes beep out from distant galaxies.

Physicists are attempting to map the distribution of the prime numbers to the energy levels of a particular quantum system.

In order to fully understand the quantum world, we may have to develop a new realm of mathematics.

For decades, researchers believed that violent supernovas forged gold and other heavy elements. But many now argue for a different cosmic quarry.

Top women in mathematics and physics discuss how they got to where they are — and why there aren’t more of them.

Computational physicist Sharon Glotzer is uncovering the rules by which complex collective phenomena emerge from simple building blocks.
