A compass pointing west

Researchers at the Paul Scherrer Institute PSI and ETH Zurich have discovered a special phenomenon of magnetism in the nano range. It enables magnets to be assembled in unusual configurations. This could be used to build ...

Star Tau Boo's baffling magnetic flips

(Phys.org) —The first observations of the complete magnetic cycle of a star other than the Sun are proving a puzzle to astronomers. Tau Boötis, known as Tau Boo (τ Boo), is a yellowish star that is a little brighter than ...

Energy from solar wind favors the north

Using information from ESA's Swarm satellite constellation, scientists have made a discovery about how energy generated by electrically-charged particles in the solar wind flows into Earth's atmosphere—surprisingly, more ...

Metal scar found on cannibal star

When a star like our sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile, researchers ...

Neptune's badly behaved magnetic field

Combining 26-year old data with supercomputer simulations, a team of scientists at Imperial College London have modelled Neptune's magnetic field in detail for the first time. The researchers find that the furthest planet ...

Heat makes electrons spin in magnetic superconductors

Physicists have shown how heat can be exploited for controlling magnetic properties of matter. The finding helps in the development of more efficient mass memories. The result was published yesterday in Physical Review Letters. ...
