The Earth and Moon, shown here in a composite of two images from the Galileo mission of the 1990s, have a long shared history. Billions…
This composite image shows a SOHO image of the Sun and an artist’s impression of Earth’s magnetosphere. Power grid failures, massive blackouts, widespread damage to…
MMS look for explosive reconnection events as it flies through the magnetopause — the boundary region where Earth’s magnetic butts up against the solar wind…
A computer simulation of the Earth’s magnetic field, which is generated by heat transfer in the Earth’s core. Credit: NASA/ Gary A.Glatzmaier By creating conditions…
[embedded content] Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America…
This stereoscopic visualization shows a simple model of the Earth’s magnetic field. The magnetic field partially shields the Earth from harmful charged particles emanating from…
A map of the Earth showing the present-day deviation from expected magnetic field direction. Strong deviations are in yellow-orange, and little deviations are in blue.…
A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth’s magnetic…
Physicists Explain Why Changes to Earth’s Magnetic Field Are Weaker Over the Pacific A new study by University of Alberta physicists provides an explanation for…
Solar wind. Credit: NASA As the Earth orbits the sun, it plows through a stream of fast-moving particles that can interfere with satellites and global…
The magnetic field is thought to be largely generated by an ocean of superheated, swirling liquid iron that makes up Earth’s the outer core 3000…
Unlike our geographic north pole, which is in a fixed location, magnetic north wanders. This has been known since it was first measured in 1831,…
This visualization shows the magnetic field around Earth, or the magnetosphere. Earth’s magnetic field origins are still a mystery, a new MIT study finds. Credit:…
A look inside the Metal Organic Vapor Phase Epitaxy (MOVPE). This machine was used to grow nanowires with hexagonal silicon-germanium shells. The emission from this…
