The 2019 Event Horizon Telescope (EHT) image was the work of hundreds of scientists and captured the first direct view of a black hole’s shadow—becoming one of the most recognized scientific images of the modern era. A team of four from CSIRO, Australia’s national science agency, has developed a powerful new imaging technique that validated the landmark 2019 image of the black hole at the center of galaxy M87.
Science fiction authors have been dreaming of robotic spacecraft harvesting fortunes from asteroids for decades. Humanity is slowly getting closer to that reality. But if you ask asteroid mining skeptics, they will usually ask one specific question—what happens to the prices of all those rare materials once someone actually brings them back? A pair of system dynamicists from MIT directly tackled that question with a new paper titled Will AstroForge Collapse the PGM Market?
Clogging is a phenomenon in which moving particles get stuck, slowing or blocking the flow, but how this transition occurs has remained experimentally unproven. Researchers from Science Tokyo studied superconducting vortices to demonstrate that clogging is a nonequilibrium phase transition. Using a two-step measurement protocol, they distinguished clogging from conventional pinning and revealed that both transitions share a critical point, offering new insights into predicting and controlling clogging across diverse systems.
Around 12 million light-years away, the supermassive black hole of the galaxy Centaurus A is hurling two enormous plasma jets into space at nearly the speed of light. These so-called jets are brighter at their edges than at their center. The reason for this was previously unclear but has now been explained by a team from the Chair of Astronomy at the University of Würzburg. The research is published in the journal Astronomy & Astrophysics.
Measurements of an argon isotope could help scientists understand whether the interiors of Uranus and Neptune, our solar system’s so-called ice giants, are dominated by ice or rock. New research led by Southwest Research Institute (SwRI) and published in The Planetary Science Journal measured the planets’ atmospheric argon-40 to estimate the amount of rock found beneath their surfaces and search for clues about the planets’ origins, including where and how they formed.
The 24-year-old had the engine running but couldn’t figure out how to get the truck moving, the Pierce County Sheriff’s Office said
Samples from the Bennu asteroid, which is currently more than 200 million miles (322 million kilometers) from Earth, and the Murchison meteorite, which fell to Earth in 1969, both contain molecules that build proteins necessary for life. New research has found that the molecules may have formed through the same process but originated far from one another in the solar system.

A new study published in Nature Materials reports that researchers have developed an aluminum gallium nitride device that combines light detection, memory and basic processing by controlling charge at polarization interfaces. The device can detect light at the nanowatt-per-square-centimeter level and operate stably at temperatures up to 300°C.
For more than 50 years, engineers have described light in optical fiber using a convenient shortcut, one that works so well it is rarely questioned. Engineers at the University of the Witwatersrand (Wits University) in Johannesburg, South Africa, have now shown that this shortcut hides a small but real effect. A magnet placed beside a multimode fiber, rather than along it, can change the light traveling inside.
In a study published in Optics Communications, a research group led by Yu Tao from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences proposed a new analytical phase readout algorithm for deep frequency modulation interferometry (DFMI).
