Astronomers have discovered a strange new signal coming from an exploding star -- a "chirp" that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared in a superluminous supernova about a billion ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While studying the paths of light rays and moving objects, ...

Scientists at Oak Ridge National Laboratory have created a new aluminum alloy called RidgeAlloy that can turn contaminated car-body scrap into strong structural vehicle parts. Normally, impurities introduced during recycling make this scrap ...

Scientists studying Mars may have uncovered a brand-new mineral hidden in the planet's ancient sulfate deposits. By combining laboratory experiments with orbital data, researchers identified an unusual iron sulfate--ferric hydroxysulfate--forming in ...

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they're far from nothing. Even in these vast empty regions, the fundamental quantum fields that fill all of space remain, ...

When NASA's DART spacecraft deliberately crashed into the asteroid moonlet Dimorphos, it did more than change the asteroid's local orbit -- it slightly shifted the path of the entire asteroid pair around the Sun. The impact blasted debris into space, ...

Scientists have found a way to significantly boost "blue energy," which generates electricity from the mixing of saltwater and freshwater. By coating nanopores with lipid molecules that create a friction-reducing water layer, they enabled ions to ...

Physicists have long struggled to unite quantum mechanics--the theory governing tiny particles--with Einstein's theory of gravity, which explains the behavior of stars, planets, and the structure of the universe. Researchers at TU Wien have now taken ...

Engineers have discovered an unexpected link between two very different realms of physics: the behavior of electrons in graphene and magnetic waves in specially engineered materials. By designing a thin magnetic film with a hexagonal pattern of holes ...

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint "Lyman-alpha" light emitted by energized hydrogen, ...
