A one second difference in the travel time of a series of seismic waves gives us an important and unprecedented glimpse of what is happening deeper inside the Earth. Theory supports our understanding of convection in the Earth’s outer core and its function in controlling the planet’s magnetic field. Convective currents or how they can … Read more
(Bloomberg) – For a generation of alienated techies, Crypto’s all-for-one ethos has been its biggest draw. Now panic is spreading across this universe – and that same ethos poses perhaps the greatest threat to its survival yet. Most read by Bloomberg What began in crypto markets this year as “risk-avoiding” selling fueled by a Federal … Read more
The blue path illustrates a core-penetrating seismic wave moving through an area in the outer core, where the seismic velocity has increased because a low-density flow has entered the area.

If you wanted to do a forensic study of the solar system, you could go to the main asteroid belt between Mars and Jupiter. That’s where you can find ancient rocks from the early days of the solar system. Out there in the cold vacuum of space, far from the sun, asteroids are largely untouched … Read more
When Jules Verne wrote “A Journey to the Center of the Earth” over 150 years ago, he envisioned a land of glowing crystals, turbulent seas, prehistoric animals and giant mushrooms. But what really lies beneath our feet remains a mystery – even today we know more about Saturn’s rings than we do about the interior … Read more
