High-speed video of the northern lights has revealed why the glorious celestial shows sometimes flicker like strobe lights: It's all about the gases.
Magnets, those objects that attract or repel each other, are more than staples of your refrigerator door. They are found in just about every laptop and the force they produce protects Earthlings from some lethal radiation from space. Live Science keeps up with the most interesting discoveries related to magnets and magnetism.
Magnetic resonance imaging (MRI) uses powerful magnets to realign a body's atoms, which creates a magnetic field that a scanner uses to create a detailed image of the body.
With the total solar eclipse on Aug. 21 only a few weeks away, astronomers have revealed what skywatchers can expect to see as the sun disappears behind the moon.
Geoscientists have discovered that regions on top of the Earth's core could behave like giant lava lamps, with blobs of rock periodically rising and falling deep inside our planet.
The photoelectric effect refers to what happens when electrons are emitted from a material that has absorbed electromagnetic radiation.
Satellites have provided a detailed view of the small but vitally important magnetic signals emitted by Earth's outer shell, known as the lithosphere, the European Space Agency (ESA) said.
Magnetically controlled swarms of microscopic robots might one day help fight cancer inside the body, new research suggests.
The Earth's geomagnetic field increased in intensity around the Levant during the late eighth century B.C. before rapidly weakening.
Are we headed to a magnetic reversal and all the global disruption that would bring? Enter archaeomagnetism. A look at the archaeological record in southern Africa provides some clues.
A band of molten iron is churning slowly deep inside Earth, much in the same way as a jet stream, a new study finds.
There's a huge hole in the sun, but it has nothing to do with alien spaceships or any other conspiracy theory.
After the magnitude 7.8 earthquake in New Zealand, bystanders reported flickering green and blue lights that are known as earthquake lights.
A moderate geomagnetic storm in Earth's magnetic field likely created some luminous auroras in the northern United States last night (Oct. 25).
