We know about our North and South poles, but what about an East, West, or slightly-to-the-left pole? According to new research published in Geophysical Research Letters, around 1 billion years ago, that might have been a possibility.
In photographs taken in the spectrum of visible light, the Sun’s magnetic field is invisible. But this image wasn’t taken in our familiar, visible wavelengths, which is why the Sun’s magnetic field is both apparent and beautiful.
In some ways, it's an ominous pitch. By measuring the "magnetic fingerprint" of any building in the world, the Finnish company IndoorAtlas can conjure up a startlingly precise indoor map of any building. It's technology that sci-fi has dreamt of for decades. But instead of surveillance, it's being used for shopping.
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.
