A new view of the proton and its excited states

The small but ubiquitous proton serves as a foundation for the bulk of the visible matter in the universe. It abides at the very heart of matter, giving rise to everything we see around us as it anchors the nuclei of atoms. Yet, its structure is amazingly complex, and the quest to understand these details has occupied theorists and experimenters alike since its discovery over a century ago.

Measuring the Unruh effect: Proposed approach could bridge gap between general relativity and quantum mechanics

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their novel approach opens new possibilities for exploring fundamental physics and for developing advanced technologies.

What 3I/ATLAS tells us about other solar systems

The earliest images of 3I/ATLAS, newly uncovered by Michigan State University, reveal how the interstellar object evolved as it traveled through our solar system—and how other distant solar systems might be different from our own.

Planet crossing starspots reveals detailed architecture of TOI-3884 system

As atmospheric observations of exoplanets become increasingly precise, it is more important than ever to correctly account for the effect of starspots on host stars. An ideal opportunity to study starspots arises when a transiting planet passes directly across them—a phenomenon known as a spot-crossing transit.

How the stuff of life could be brought to Europe’s Mars Rover by rockfalls and ancient floods

The Rosalind Franklin mission’s chance of finding evidence of past life on Mars has been boosted by two studies that show that the rover won’t have to travel far to find materials potentially laden with organic molecules. Instead, natural processes could bring those materials to the rover, as revealed in two separate presentations at the EPSC–DPS2025 Joint Meeting in Helsinki this week.

Signs of ancient life may have been found in Martian rock—new study

Just over a year ago, NASA made a remarkable announcement. The Perseverance rover had found potential signs of ancient life on Mars. Now, the technical details behind that discovery have been published in a Nature paper that, despite its rather modest wording, may ultimately prove to be among the most significant in the history of science.

Ten years ago, gravitational waves changed astronomy. A new discovery shows there’s more to come

Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a key prediction from Albert Einstein’s theory of general relativity and began a new era of astronomy.

JWST finds an exoplanet around A pulsar whose atmosphere is all carbon

Science advances through data that don’t fit our current understanding. At least that was Thomas Kuhn’s theory in his famous On the Structure of Scientific Revolutions. So scientists should welcome new data that challenges their understanding of how the universe works.

Discovery of new moon or ring system orbiting mysterious distant planet Quaoar

Astronomers have discovered what they think may be another moon orbiting a distant dwarf planet called Quaoar. This small, icy, egg-shaped planet in the far reaches of our solar system, beyond Neptune, is already known to have two rings and a moon, but this discovery was unexpected and accidental.
