Origin of 'theta aurora'—long-standing space mystery—revealed
Auroras are the most visible manifestation of the sun's effect on Earth, but many aspects of these spectacular displays are still poorly understood. Thanks to the joint European Space Agency and NASA's Cluster ...
Moon's molten, churning core likely once generated a dynamo
When the Apollo astronauts returned to Earth, they brought with them some souvenirs: rocks, pebbles, and dust from the moon's surface. These lunar samples have since been analyzed for clues to the moon's ...
Sun's rotating 'magnet' pulls lightning towards UK
(Phys.org) —The Sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper ...
Magnetic fields frozen into meteorite grains tell a shocking tale of solar system birth
The most accurate laboratory measurements yet made of magnetic fields trapped in grains within a primitive meteorite are providing important clues to how the early solar system evolved. The measurements point ...
New evidence for an exotic, predicted superconducting state
Superconductors and magnetic fields do not usually get along. But a research team led by a Brown University physicist has produced new evidence for an exotic superconducting state, first predicted a half-century ...
Fermi satellite finds hints of starquakes in magnetar 'storm'
(Phys.org) —NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009. Now astronomers analyzing ...
Earth's magnetic field could flip within a human lifetime
Imagine the world waking up one morning to discover that all compasses pointed south instead of north.
