How a jeweler’s trick may unlock next-generation nuclear clocks

Scientists have found an unexpectedly simple way to advance one of the most precise technologies ever imagined: the nuclear clock. Using a technique inspired by...

Did black holes change over time? Astronomers question a 50-year-old rule about quasars

Astronomers have uncovered surprising evidence that challenges a long-standing rule about quasars, some of the brightest objects in the universe. The discovery suggests that the...

Why the same galaxy can grow or decline—It depends on its neighbor

Galaxies may look serene from afar, but their lives are shaped by powerful internal structures and by the neighbors they keep. A new study led...

Webb spots the ‘smoke’ from crashing exocomets around a nearby star

The James Webb Space Telescope (JWST) was involved in yet another first discovery recently available in pre-print form on arXiv from Cicero Lu at...

Why quantum computers “remember” their mistakes—and why that matters

Quantum computers promise to solve problems far beyond the reach of today’s machines, but there is a stubborn obstacle standing in the way: errors. Unlike...

Scientists solve a big bang theory puzzle that could point to dark matter

For years, one of the most intriguing mysteries in physics has been dark matter—an invisible substance thought to make up most of the matter...

New study reveals a massive hidden alphabet inside entangled light

Quantum entanglement is often described as a mysterious link between particles, but new research shows it may be even richer than scientists once imagined. A...

Astronomers find the first compelling evidence of monster stars in the early universe

One of the greatest mysteries the James Webb Space Telescope (JWST) was developed to investigate was the birth of supermassive black holes (SMBHs). For more...

A year that mattered: Caltech’s scientific journey in 2025

Caltech is a place unlike any other, an Institute that is truly "small but mighty." Its small size and the expertise of its community enable...

Gaia space telescope spots possible planets forming around baby stars

How do planets like Earth and Jupiter come into existence? Astronomers are beginning to answer that question thanks to new observations from the European Space...
