A sudden X-ray flare from a supermassive black hole in galaxy NGC 3783 triggered ultra-fast winds racing outward at a fifth the speed of light--an event never witnessed before. Using XMM-Newton and XRISM, astronomers caught the blast unfold in real . ...

New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star formation, shifts in flowing gas, and even streams of . ...

A remarkably clean gravitational-wave detection has confirmed long-standing predictions about black holes, including Hawking's area theorem and Einstein's ringdown behavior. The findings also provide the strongest support yet that real black holes .. ...

Researchers have built a fully implantable device that sends light-based messages directly to the brain. Mice learned to interpret these artificial patterns as meaningful signals, even without touch, sight, or sound. The system uses up to 64 micro .. ...

XRISM's high-precision X-ray data revealed unusually strong signatures of chlorine and potassium inside the Cassiopeia A supernova remnant. These levels are far higher than theoretical models predicted, showing that supernovae can be major sources of ...

Knotted structures once imagined by Lord Kelvin may actually have shaped the universe's earliest moments, according to new research showing how two powerful symmetries could have created stable "cosmic knots" after the Big Bang. These exotic objects ...

Scientists have discovered that moonquakes, not meteoroids, are responsible for shifting terrain near the Apollo 17 landing site. Their analysis points to a still-active fault that has been generating quakes for millions of years. While the danger to ...

SQUIRE aims to detect exotic spin-dependent interactions using quantum sensors deployed in space, where speed and environmental conditions vastly improve sensitivity. Orbiting sensors tap into Earth's enormous natural polarized spin source and ...

New findings challenge the widespread belief that AI is an environmental villain. By analyzing U.S. economic data and AI usage across industries, researchers discovered that AI's energy consumption--while significant locally--barely registers at ...

SPHERE's detailed images of dusty rings around young stars offer a rare glimpse into the hidden machinery of planet formation. These bright arcs and faint clouds reveal where tiny planet-building bodies collide, break apart, and reshape their systems ...
