Scientists at the Australian National University have made a highly unusual discovery thousands of kilometers beneath the Earth's surface: a doughnut-shaped structure within our planet's liquid core.

The torus is the size of our entire solar system. The astronomers first caught this "stellar snacking event" on March 1, 2022, with the All-Sky Automated Survey for Supernovae ( ASAS-SN (Opens in ...

Project TORUS–or Targeted Observation by Radars and UAS of Supercells – is a partnership between CU Boulder, the University of Nebraska-Lincoln (which is leading the work), Texas Tech University, the ...

For geologists, this is fascinating stuff. The radius of the Earth is just shy of 4,000 miles and the deepest well anyone has ever dug is a little over 7.5 miles deep. The crust under the Earth ...

Cloud-to-ground lightning strikes simulated in a biosphere mimicking conditions on a young Earth led to chemical reactions resulting in "remarkable yields" of the building blocks for life.

Something is ‘pulsing’ beneath the Earth, scientists say – and it could tear a continent apart. Rhythmic surges are like a ‘heartbeat’ under the ground ...

Scientists at the Australian National University have made a highly unusual discovery thousands of kilometers beneath the Earth's surface: a doughnut-shaped structure within our planet's liquid core.

The Earth's outer core, a band of fluid metal roughly 1,400 miles thick, is composed of mostly iron and nickel. Scientists believe the volatile swirling of this ferrous liquid generates the planet ...
