PostSubject: Earth's Cries Recorded in Space   Wed Jul 02, 2008 10:23 pm

http://news.yahoo.com/s/space/200807...ecordedinspace

Earth emits an ear-piercing series of chirps and whistles that could be heard by any aliens who might be listening, astronomers have discovered.
The sound is awful, a new recording from space reveals.

Scientists have known about the radiation since the 1970s. It is created high above the planet, where charged particles from the solar wind collide with Earth's magnetic field. It is related to the phenomenon that generates the colorful aurora, or Northern Lights.

The radio waves are blocked by the ionosphere, a charged layer atop our atmosphere, so they do not reach Earth. That's good, because the out-of-this-world radio waves are 10,000 times stronger than even the strongest military signal, the researchers said, and they would overwhelm all radio stations on the planet.

Theorists had long figured the radio waves, which were not well studied, oozed into space in an ever-widening cone, like light from a torch.

But new data from the European Space Agency's Cluster mission, a group of four high-flying satellites, reveals the bursts of radio waves head off to the cosmos in beam-like fashion, instead.

This means they're more detectable to anyone who might be listening.

The Auroral Kilometric Radiation (AKR), as it is called, is beamed out in a narrow plane, as if someone had put a mask over a torch and left a slit for the radiation to escape.

This flat beam could be detected by aliens who've figured this process out, the researchers say. The knowledge could also be used by Earth's astronomers to detect planets around other stars, if they can build a new radio telescope big enough for the search. They could also learn more about Jupiter and Saturn by studying AKR, which should emit from the auroral activity on those worlds, too.

"Whenever you have aurora, you get AKR," said Robert Mutel, a University of Iowa researcher involved in the work.

The AKR bursts -- Mutel and colleagues studied 12,000 of them -- originate in spots the size of a large city a few thousand miles above Earth and above the region where the Northern Lights form.

"We can now determine exactly where the emission is coming from," Mutel said.

Our planet is also known to hum, a mysterious low-frequency sound thought to be caused by the churning ocean or the roiling atmosphere.

Wow---neat article! Geesh, we must sound pretty bad to the aliens! grinsmiley

I couldn't get the link to work though...did you guys actually get to a link where you hear Earth 'scream'? :think:

I think maybe the link was just incomplete? Within the article, there is a link to audio that you can click on.

Oh, now that is interesting. You know what it brings to my mind? The Bible speaks about this very thing! It talks about the creation itself crying out praises to God.

Isaiah 44:23 ....."shout ye lower parts of the earth: break forth into singing, ye mountains........"
Rom. 8:22 "For we know that the whole creation groaneth and travaileth in pain together until now."

In Luke 19, the Pharisees told Jesus to make the disciples stop praising Him and the Father........and He responded that if they held their peace, the stones would cry out.

- and other verses, too, of course. But it's cool that science is catching up with the Bible. grinsmiley
