The Earth and other planets babble and chirp
Earth emits an ear-piercing series of chirps and whistles that could be heard by anyone who might be listening, astronomers have discovered. Earth emits an ear-piercing series of chirps and whistles that could be heard by anyone who might be listening, astronomers have discovered. 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.
Our planet is also known to hum, a mysterious low-frequency sound thought to be caused by the churning ocean or the roiling atmosphere.
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.
These radio waves fan out from starting points in the atmosphere in a narrow plane rather than a cone shape, as was long expected. into space in an ever-widening cone, like light from a torch.
This means they’re more detectable to anyone who is able to pick up the signals.
Recently launched spacecraft have also spotted auroral lights and AKR coming from Jupiter and Saturn. these are some of the sounds coming from Saturn.
Could we use other stars, asteroids and planets babble to find out if anyone else is babbling in space or …?
What do you think – Is Santa calling or should ET phone home?
