The European Space Agency (ESA) has released the first batch of survey data from its €1.4bn Euclid mission. The release includes a preview of its ‘deep field’ where in just one week of observations, Euclid already spotted 26 million galaxies as well as many transient phenomena such as supernovae and gamma-ray bursts. The [...]

Author(s): Katherine WrightThe Euclid satellite released its first trove of galaxy data based on seven days of deep-field observations in three sky areas.[Physics 18, 64] Published Wed Mar 19, 2025 [...]

Researchers have demonstrated that they can remotely detect radioactive material from 10 m away using short-pulse CO2 lasers – a distance over ten times farther than achieved via previous methods. Conventional radiation detectors, such as Geiger counters, detect particles that are emitted by the radioactive material, typically limiting their operational range [...]

A recent study has shed new light on the dynamic evolution of solar prominences. By integrating high-resolution observational data from the one-meter New Vacuum Solar Telescope (NVST) with spectral observations from NASA's Interface Region Imaging Spectrograph (IRIS) satellite, researchers identified distinct dynamic features in different regions of solar prominences, providing [...]

The Square Kilometre Array (SKA) Observatory has released the first images from its partially built low-frequency telescope in Australia, known as SKA-Low. The new SKA-Low image was created using 1024 two-metre-high antennas. It shows an area of the sky that would be obscured by a person’s clenched fist held at arm’s [...]

“I could have sworn I put it somewhere safe,” is something we’ve all said when looking for our keys, but the frustration of searching for lost objects is also a common, and very costly, headache for civil engineers. The few metres of earth under our feet are a tangle of [...]

In MIT’s 2025 Killian Lecture, physicist John Joannopoulos recounts highlights from a career at the vanguard of photonics research and innovation. When you’re challenging a century-old assumption, you’re bound to meet a bit of resistance. That’s exactly what John Joannopoulos and his group at MIT faced in 1998, when they put [...]

From the Global Physics Summit in Anaheim, California The greatest pleasure of being at a huge physics conference is learning about the science of something that’s familiar, but also a little bit quirky. That’s why I always try to go to sessions given by undergraduate students, because for some reason [...]

At the center of most large galaxies, including our own Milky Way, sits a supermassive black hole. Interstellar gas periodically falls into the orbit of these bottomless pits, switching the black hole into active galactic nucleus (AGN)-mode, blasting high-energy radiation across the galaxy. [...]

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a key target for planet formation studies. [...]

A new study probing quantum phenomena in neurons as they transmit messages in the brain could provide fresh insight into how our brains function. In this project, described in the Computational and Structural Biotechnology Journal, theoretical physicist Partha Ghose from the Tagore Centre for Natural Sciences and Philosophy in India, together [...]

I spent most of Saturday travelling between the UK and Anaheim in Southern California, so I was up very early on Sunday with jetlag. So just as the sun was rising over the Santa Ana Mountains on a crisp morning, I went for a run in the suburban neighbourhood just [...]
