Astronomers may have found an explanation for one of the biggest mysteries revealed by the James Webb Space Telescope (JWST): why so many galaxies in the early universe appear unexpectedly bright in ultraviolet light. The new study, posted to the arXiv preprint server on May 11, suggests that galaxies more than 13 billion years ago were filled with an unusual kind of dust produced directly by supernova explosions, which could help explain why galaxies appeared so bright.
Neurons, the uber-connected nerve cells that act as a main switchboard for the brain, are central to some incredibly complicated processes. They make it possible to think, walk, speak, and breathe. They even have built-in backup batteries to use in emergencies.
Police across the country say realistic-looking water guns and surprise ambushes are turning this high school tradition into a public safety concern
NASA’s Perseverance Mars rover used its Mastcam-Z camera to capture this panorama of an area nicknamed “Arbot” on April 5, 2026, the 1,882nd Martian day (sol) of the mission, during the rover’s deepest push west beyond Jezero Crater.
Quantum materials, materials with properties that are influenced by the laws of quantum mechanics, have attracted considerable attention over the past few decades. Their unique properties make these materials advantageous for the development of numerous cutting-edge technologies, including quantum computers, highly sensitive sensors and energy-efficient electronics.
In recent years, atomically thin materials—crystals only a few atoms thick—have attracted growing attention because they can exhibit physical properties that do not appear in conventional bulk materials. Among them, atomically thin magnetic materials are particularly intriguing, as they can host unconventional magnetic states and offer new possibilities for spin-based electronic technologies.
Imagine a laptop that never gets hot, a phone that holds its charge for days, or a computer memory chip designed to permanently retain data, even when the power goes out. This is the possibility sitting inside a remarkable family of materials that a team of researchers from the University of Ottawa and the Massachusetts Institute of Technology (MIT) has spent years trying to understand, and they just published a comprehensive roadmap of the field to date in the journal Newton.
When it comes to space debris, what goes up is coming down more often—and not safely.
Astronomers have tracked a dramatic “changing-look” active galactic nucleus (AGN) whose central supermassive black hole appeared to switch off and then rapidly reignite. The galaxy, HE 1237−2252, dimmed in X-rays by a factor of 17 within just 18 months before recovering again. The paper outlining its analysis was uploaded to the arXiv preprint server on May 8.
Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron produced in stellar explosions. This has now been confirmed by an international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) through the analysis of Antarctic ice tens of thousands of years old. From the steady but time-varying influx, the researchers conclude that the radioactive isotope has been stored within the cloud since a long-past stellar explosion. The results have been published in the journal Physical Review Letters.
Hundreds of companies raised a combined $70 billion by selling shares to the public in the United States last year.
A joint European-Chinese spacecraft is set to blast off Tuesday to investigate what happens when extreme winds and giant explosions of plasma shot out from the sun slam into Earth’s magnetic shield.
Every four years, the men’s World Cup delivers some certainties. The pitch dimensions are tightly regulated, offside is signaled with a flag, and referees end the match with a blast of a whistle. But one key piece of equipment is changed on purpose: the ball.
Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three types, or “flavors”: a phenomenon known as neutrino oscillation that remains poorly understood in extreme astrophysical environments.
Groton Police Officers Bryan Albee and Cristopher Brillon engaged with the man for several minutes, ultimately persuading him to climb down from the barrier
