NASA’s Solar Dynamics Observatory just released a stunning video showing a pair of magnetic fields as they duel for supremacy on the surface of the sun.
From our perch here on Earth, the sun seems pretty uniform from day to day. But a closer look in this new magnetic map reveals that it’s teeming with activity—and with some intriguing bright spots.
Some animals are capable of magnetoreception—an added sense that helps them detect magnetic fields. European scientists have now learned that the molecule responsible for this trait is also found in the eyes of dogs and some primates, which suggests they too might be capable of seeing magnetic fields.
Astronomers from Wesleyan University have detected the shock waves produced by a high-speed “hot Jupiter” exoplanet caught in a tight orbit around its host star. It’s a potential indication of an incredibly powerful magnetic field around the planet.
A rather massive coronal hole was recently spotted on the Sun by NASA’s Solar Dynamics Observatory. The region—the size of 50 Earths—is spewing material into space at tremendous speeds. It may look terrifying, but astronomers say it’s nothing to worry about.
Earth's magnetic field is constantly shifting, and roughly every 200,000 to 300,000 years it flips north and south completely. We're currently overdue for a switcheroo—and scientists now say it could happen in a time as short as 100 years, potentially altering life in unexpected ways.
Remember how awesome it was to hold up a magnet to an old CRT display, and then watch it degauss in a colorful, rainbow seizure? Well you probably don't have any CRTs on hand anymore, but German artist Carsten Nicolai has an installation that makes use of those same magnetic deformations, and it's still fun to watch.
So, that's another one the birds have on us. In addition to flight and colorful plumage, they're also equipped with magnetometer beaks that can sense magnetic fields and use them as a map. Yes, even chickens.
Yesterday, I showed you a great video of NASA scientists explaining how magnetic fields work over beautiful animations making the fields come to life. Today, now that you're all caught up on how the fields work, I'll show you how geophysicist Dan Lathrop is building a fake planet filled with liquid sodium that will,…
Magnetic fields are invisible, at least usually. But Scientists from NASA's Space Sciences Laboratory have made them visible as "animated photographs," using sound-controlled CGI and 3D compositing. It makes the fields, as explained by the scientists, dance in an absolutely gorgeous movie called Magnetic Movie. You…
This field has 1,301 florescent bulbs planted in it, and they're all glowing. They aren't plugged into anything, however; they're powered solely from the magnetic fields produced by the power lines above. It's all a large art project by Richard Box, and if you're really interested in it you can order a DVD of the…
