Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at ...

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number ...

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and ...

A new image captured by the Very Large Telescope reveals stars and gas orbiting the "invisible giant" at the heart of our galaxy.

Most materials, especially metals and ceramics, are crystals. Their atoms are arranged in three-dimensional lattices that repeat the same exact pattern, over and over again. But there's a well-known ...

The comet formed in a cold and distant part of the early Milky Way up to 12 billion years ago, putting it just under 2 billion years the age of the universe.

The fragile-looking filaments of cooled lava known as Pele’s hair can form when pockets of bubble-rich lava pull apart rapidly, experiments suggest. Among all the ways that molten rock can solidify ...
