Study Reveals the Shape of a Photon for the First Time Ever
A study conducted at the University of Birmingham has identified the precise shape of a single photon, reshaping how interactions between light and matter at the quantum level are understood. The study detailed in Physical Review Letters tells us how photons, or particles of light, are emitted and influenced by their surroundings, offering possibilities for significant technological advancements.
This achievement stems from addressing a longstanding challenge in quantum physics: the near-infinite ways photons can propagate in their environment. Researchers grouped these scenarios into manageable sets, enabling a model to describe not just how photons interact with their emitters but also how energy radiates into the far field. The findings also included the first-ever visualisation of a photon, achieved through complex calculations.
Complex Problems Made Solvable
Dr Benjamin Yuen, a physicist at the University of Birmingham and lead author of the study, explained that the team converted an otherwise insurmountable problem into a computationally solvable framework. As a result, they could depict the shape of a photon—a significant milestone in quantum physics.
Photon Emission Shaped by Environment
The study, published in the Physical Review Letters, also reveals the critical role of environmental factors, including geometry and optical properties, in defining a photon’s characteristics. According to Professor Angela Demetriadou, co-author of the research, these influences extend to the photon’s colour, shape, and likelihood of being emitted. The data, previously dismissed as background noise, now serves as a valuable source of information.
Advancing Light-Matter Applications
This discovery is expected to advance the design of nanophotonic technologies. Dr. Yuen highlighted its potential to develop improved sensors, solar cells, and systems for quantum computing. A more detailed understanding of light-matter interactions could also lead to breakthroughs in secure communication and molecular-level chemical processes.
By visualising a photon for the first time, the research establishes a foundation for future exploration, marking a significant step forward in understanding the quantum world.

The gas giant TOI-2109b is more than five times as massive as Jupiter, and resides in a perilous orbit 870 light-years from our planet. As an “ultrahot Jupiter,” it completes a lap around its parent star in a mere 16 hours, the briefest orbit of any such planet known. It is baking its atmosphere to broiling temperatures, and inching closer to oblivion in an orbit that is slowly pulling it in toward its parent sun. Using archived space telescope data from TESS and Cheops, astronomers have observed the testimony of this inevitable spiral, and contemplated three (wildly divergent) possible fates of the doomed planet.
Fates for TOI-2109b
According to the new research, conducted with data from NASA’s TESS and ESA’s Cheops missions shows that TOI-2109b’s orbit is decaying — a process it will continue for thousands of Earth’s years to come by 10 seconds over three Earth years. This proves that it is in a process of slow in fall. If the decay becomes worse, the planet may start falling directly into its host star and create a luminous flare, just like ZTF SLRN-2020. Alternatively, the star’s tidal forces could permanently warp the planet and rip it asunder.
A Potential Planetary Rebirth
There is a third, less-tragic possibility which could happen through a process of photoevaporation, in which strong radiation from the hosting star removes TOI-2109b’s gaseous envelope to reveal its rocky core. If the planet shrinks quickly enough, it might survive the process, avoiding its destruction by spiraling within its eternal Roche limit, and settling as a super-Earth or Neptune-sized blow-up hard relic. Then TOI-2109b would be an odd, rare opportunity to witness up close how this process unfolds.

The Hubble Space Telescope has taken its initial shots of comet 3I/ATLAS, a comet visiting us from beyond our solar system that recently fell apart — but not before it struck a pose for the cameras. It’s only the third such object ever known, after 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019. The subject of numerous scientific tweets and some frantic searches by astronomers anxious to figure out just what it is — and where it came from — before it is gone into the pitch black of deep space forever, 3I/ATLAS was first sighted by the ATLAS survey telescope on July 1, 2025.
Ancient Interstellar Comet 3I/ATLAS Offers Clues to Planetary Systems Beyond Our Own
According to As per Space.com, recent studies indicate that 3I/ATLAS could be some 7 billion years old, well beyond the 4.6 billion years of our solar system. That’s an indication that the comet arose in the more ancient parts of the Milky Way, which would give researchers a rare glimpse of what the early days of other planetary systems were like. Undergraduate researcher Astrafoxen first flagged the Hubble images on Bluesky, noting the comet’s “nice and puffy” coma, despite interference from cosmic rays.
A newly available preprint paper has already revealed that 3I/ATLAS contains abundant water ice and a dust makeup resembling D-type asteroids—organic-rich bodies typically found in the outer solar system. Unlike ultrared trans-Neptunian objects, D-types are believed to have high carbon and silicate content, potentially shedding light on the comet’s deep-space origins and volatile chemistry.
The comet 3I/ATLAS was discovered just as the Vera C. Rubin Observatory was gearing up to carry out its initial observations of the heavens, dovetailing with the LSST’s expected discovery of many more interstellar objects in the coming decade.
Until then, 3I/ATLAS holds the astronomical spotlight. Its brief solar system passage offers a precious opportunity for researchers to analyse the material makeup of alien planetary systems. The Hubble images, now available for download, are expected to aid future papers as scientists continue to unravel the story of this ancient cosmic traveller.
