New observations are challenging a hypothesis about what produces these energetic bursts of radio waves.

As the climate crisis continues to affect the American West, sunken boats and human remains aren’t the only surprises to be revealed by record-low water levels at Lake Mead. Sedimentary rocks that hadn’t been seen since the 1930s are now exposed along the constantly changing shoreline, and a UNLV study of the deposits has discovered that many of these rocks also contain ash from volcanoes as far away as Idaho, Wyoming, and California that rained down on Southern Nevada as many as 12 million years ago.

Lake Mead's receding water levels are now revealing ancient volcanic eruptions from millions of years ago.

A peculiar repeating fast radio burst seems to be coming from a dynamic environment in an otherwise uninteresting region, leaving researchers scratching their heads as to the burst’s origin.

Mysterious fast radio bursts release as much energy as the Sun pours out in a year - and newly published research has deepened the mystery around them.

A diamond contains the only known sample of a mineral from Earth’s mantle—and hints at oceans’ worth of water hidden deep within our planet

The mineral may shake things up by changing its identity at high pressure and temperature

A blue flaw in a gem-quality diamond from Africa is a tiny fragment of Earth's deep interior, and it suggests our planet's mantle contains oceans' worth of water.

We have detected a strange new signal from across the chasm of time and space. A repeating fast radio burst source detected last year was recorded spitting out a whopping 1,863 bursts over 82 hours, amid a total of 91 hours of observation.

An international team of scientists using the world’s largest radio telescope has detected a mysterious series of bright flashes from 3 billion light years away.

More than 15 years after fast radio bursts were discovered, new research has both unraveled and deepened the mystery of the sources of these deep space phenomena.

Fast radio bursts (FRBs) are intense pulses of radio wave energy that usually last only a matter of milliseconds and come from somewhere deep in the cosmos. Astrophysicists detect these signals emanating mostly from faraway galaxies, but they do not yet understand the origin of the pulses. The bursts are extremely intense at their source, putting out as much energy in one millisecond as the Sun does in an entire day. However, by the time they reach earth they are very weak and difficult to detect.
