The planet's magnetic field seems to be 10 times weaker than it was six months ago.
The energy-efficient skyTran system uses autonomous, two-person pods suspended 20 feet in the air. Continue reading →
The European Planck space telescope has looked deep into the Milky Way's light, revealing its vast magnetic field. Continue reading →
Three satellites -- dubbed the Swarm -- are mapping the Earth's magnetic field in record time. Continue reading →
Magnetars are the most magnetically-dense objects known in the Universe and now astrophysicists may have found one of these stellar husks being choked by a magnetic noose, causing it to wobble. Continue reading →
Astronomers have detected a weird hiccup in a pulsar's spin -- did it just blend-up an asteroid smoothie? Continue reading →
Scientists have captured their best view yet of how extreme magnetic fields shape superfast jets from the most powerful explosions in the universe.
The sun and the Earth like to flip their magnetic fields, but they do it for very different reasons. Neither seem particularly dangerous, however.
