Universe Idol: We sound so bad aliens would vote us out the first week

No wonder aliens want to attack the Earth with such regularity in the movies. From out in space, we sound pretty annoying, like that renter in the apartment above you who insists on playing Yoko Ono records at 2:30 in the morning.

You laugh, but new recordings from space show that Earth, our home, makes an array of nasty sounds that ring out across the universe.

Scientists have actually known about this phenomenon since the 1970s. But today we have some audio evidence of this annoying noise. So what’s happening?

There’s a bunch of radiation created high above our planet. Solar winds blow it into Earth’s magnetic field and then things start to get loud. Basically, this radiation gets sucked into the same conditions that cause the Northern Lights. While they look great, they sound horrible – sorta like Brittney Spears.

Earth’s ionosphere keeps the radio waves created in this action from coming down toward us, which is a good thing. That’s because they’re about 10,000 times stronger than any radio signals we have on our planet.

Satellites from the European Space Agency's Cluster mission, however, have now detected strong beams of these annoying radio waves out in space.

Click here to hear a sample of what this space noise sounds like. Personally, I think I’ve experienced this sound, much quieter, after eating a bad burrito.

It's not quite so majestic as you might expect from the northern lights, but I don't really mind it. It's like a flock of tiny robo-birds.
