Earth's magnetic field shields the planet from charged particles streaming from the sun, keeping it from becoming a barren, Mars-like rock. For more than 300 years, scientists have recorded a westward ...

The most detailed image of 'Pillars of creation'. These towering tendrils of cosmic dust and gas sit at the heart of M16, or the Eagle Nebula. The blue colors in the image represent oxygen, red is ...

An artist's impression of the Fermi Gamma ray Space Telescope (FGST) in orbit. Nasa Left-handed spiral magnetic fields imprinted on gamma rays detected by Nasa's Fermi space telescope indicate why the ...

This video explains how magnets work and how magnetic fields are generated by the movement of electric charges. Magnetic materials influence and interact with current, motion, and force, making them ...

Study shows Earth could witness more rapid magnetic field reversal. Pictured, a schematic illustration of Earth's magnetic field. NASA / Peter Reid, The University of Edinburgh In the late 1970s, it ...

Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some ...

Scientists have discovered that the 'weak spot' in Earth's magnetic field is growing, allowing harmful radiation to come closer to our planet's surface. The region, known as the South Atlantic Anomaly ...

Scientists believe they have an answer for why the North Magnetic Pole has been moving from Canada towards Siberia. The North Magnetic Pole is a point on the Earth’s surface, at which the planet’s ...

Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. An MRI scanner is a large tube that contains ...

Engineers from MIT have designed soft, 3D-printed structures that can transform their shape "almost instantaneously" with the wave of a magnet. The magnetically manipulated objects are made using a ...
