LISTEN: Eerie sound coming from Rosetta's comet sounds a lot like...

KHQ.com - On Wednesday, the Rosetta spacecraft and its Philae lander made history by landing on Comet 67P/Churyumov-Gerasimenko. On Thursday the European Space Agency released audio of the comet "singing," and it's pretty creepy. 

Why? Because it sound eerily similar to the "Predator." You know, the alien creature that hunted Arnold Schwarzenegger in 1987 in what I consider to be the second greatest movie of all-time (the greatest movie of all time is Die Hard, in case you were wondering). 

Anyway, of course sound waves can't travel through space, so this isn't a direct audio recording for you science buffs who are already calling malarkey on this. So here's what the smart scientists attached to the mission are saying about the "singing": 

"One observation has taken the RPC scientists somewhat by surprise. The comet seems to be emitting a ‘song' in the form of oscillations in the magnetic field in the comet's environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased by a factor of about 10,000.

The music was heard clearly by the magnetometer experiment (RPC-Mag) for the first time in August, when Rosetta drew to within 100 km of 67P/C-G. The scientists think it must be produced in some way by the activity of the comet, as it releases neutral particles into space where they become electrically charged due to a process called ionisation. But the precise physical mechanism behind the oscillations remains a mystery."

Got that? Me neither, but if you've seen Predator, then you'll hear this and think exactly what I did: "Get to the choppa!"

Listen to both the comet (compiled by German composer Manuel Senfft) and the Predator side-by-side above this article. Pretty cool, huh?

    RATHDRUM, Idaho - A family said their main priority right now is keeping their sick baby comfortable. They were recently told by doctor's their 19month-old daughter isn't expected to live much longer. They said one of the only things that eases her pain is a specialty chair that insurance won't cover. That's when friends said, "Help Me Hayley."
