Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...
The moving metals in Earth's core create the planet's magnetic field. Our planet sits in a small corner of the Milky Way galaxy, 25,000 light-years from the galaxy's center. Our solar system lives ...
Every magnet has two poles ... the material becomes magnetic. The strongest magnets are made from ferromagnetic metals, which include iron, nickel, cobalt, and some rare earth elements like ...
Earth's axis is currently tilted at a 23.5-degree angle away from vertical as it rotates around the sun, affecting how much solar energy hits each of the poles, in particular. But the tilt of ...
High above Earth's poles ... about a million amps of electrical charge around the poles every second. They can create some of the largest magnetic disturbances on the ground, and rapid changes ...
Fresh satellite data shows that sea ice at both the North and South Poles shrank to a combined extent of about ... Together, these conditions seem to be undoing some of the natural insulation that ...
What If is a Webby Award-winning science web series that takes you on a journey through hypothetical worlds and possibilities, some in distant corners of the universe, others right here on Earth." ...
Earth’s magnetic poles are constantly on the move, but they haven’t drifted far enough to actually flip in the modern age. Researchers know that Earth’s poles have flipped in the past ...
