Astronomers in India have identified 53 previously unknown giant radio quasars powered by supermassive black holes, each releasing enormous plasma jets reaching up to 7.2 million light-years—nearly 50 times the Milky Way’s diameter. Using GMRT data, the team expanded the catalog of known giant quasars and offered valuable clues about how black holes grow, merge, a…

Engineers have transformed discarded crustacean shells into functional biohybrid robots by softening the shell segments, adding elastomers, and attaching motors. These recycled structures can lift weight, grasp delicate items, and even propel small swimmers. The project demonstrates how food waste can become a sustainable robotics resource, though challenges remain wi…

A powerful X5.1 solar flare on November 11, 2025, sent high-speed protons toward Earth, producing the strongest radiation spike detected in nearly two decades. The event caused a rare ground-level enhancement, briefly raising radiation at flight altitude to ten times normal. While not dangerous this time, scientists warn larger flares could threaten avionics and commu…

Astronomers have identified a 50-million-light-year-long cosmic filament in which 14 gas-rich galaxies all rotate in sync with the structure itself. The filament, mapped about 140 million light-years away, appears young, cold and shaped by slow cosmic flows. Galaxies on opposite ends move in opposite directions, suggesting the entire filament is spinning.
