### New Proof Finds the ‘Ultimate Instability’ in a Solar System Model

For the first time, mathematicians have proved that planetary orbits in a solar system will always be unstable.

### The Tiny Physics Behind Immense Cosmic Eruptions

A new theory describes how particle interactions fuel fast magnetic reconnection, the process behind solar flares and other astrophysical jets.

### Physicists Create Elusive Particles That Remember Their Pasts

In two landmark experiments, researchers used quantum processors to engineer exotic particles that have captivated physicists for decades. The work is a step toward crash-proof quantum computers.

### A New Idea for How to Assemble Life

If we want to understand complex constructions, such as ourselves, assembly theory says we must account for the entire history of how such entities came to be.

### Is Perpetual Motion Possible at the Quantum Level?

A new phase of matter called a “time crystal” plays with our expectations of thermodynamics. The physicist Vedika Khemani talks with Steven Strogatz about its surprising quantum behavior.

### Tiny Jets on the Sun Power the Colossal Solar Wind

A new analysis argues that ubiquitous eruptions in the sun’s corona explain the vast flow of charged particles seen streaming out through the solar system.

### A New Symmetry Shakes Up Physics

So-called “higher symmetries” are illuminating everything from particle decays to the behavior of complex quantum systems.

### The Electron Is So Round That It’s Ruling Out Potential New Particles

If the electron’s charge wasn’t perfectly round, it could reveal the existence of hidden particles. A new measurement approaches perfection.

### How to Tame the Infinities Hiding in the Heart of Particle Physics

In the math of particle physics, every calculation should result in infinity. The set of techniques known as “resurgence” points toward an escape.
