Our Planet's 'Electrical Heartbeat' Can Be Seen From Space!

MessageToEagle.com - Our planet Earth has a heartbeat which can be seen from space and behaves like an enormous electric circuit.

The atmosphere is actually a weak conductor and if there were no sources of charge, its existing electric charge would diffuse away in about 10 minutes.

There is a 'cavity 'defined by the surface of the Earth and the inner edge of the ionosphere 55 kilometers up, in which electromagnetic waves propagate. At any moment, the total charge residing in this cavity is 500,000 Coulombs.

At any given moment about 2,000 thunderstorms roll over Earth, producing some 50 flashes of lightning every second. Each lightning burst creates electromagnetic waves that begin to circle around Earth captured between Earth's surface and a boundary about 60 miles up.

Some of the waves if they have just the right wavelength combine, increasing in strength, to create a repeating atmospheric heartbeat

This fascinating phenomenon is called Schumann resonance.

According to recent study conducted by scientists at the University of Reading, the height of clouds changes by up to 200m during a day under the influence of a global 'electrical heartbeat' in the atmosphere.

The findings, made by analysing 10 years' data of cloud heights from the north and south poles, open up a whole new perspective on our understanding of how clouds form and influence our weather and climate.

Scientists have been aware of the daily global ebb and flow of electric current through the atmosphere for 100 years, when it was shown to vary consistently throughout the day wherever on the planet it was measured.

The electric current is caused by electrified storms across the world. Its daily peak occurs at 7pm GMT each day when the major sources of thunderstorms are the American and African landmasses.

The current is usually weakest at 3am GMT, night-time across most of the world's continents, when there are fewest thunderstorms occurring globally.


Clouds follow earth's 'electrical heartbeat'


Previously no connection had been made between this current and the formation of clouds. But, by analysing cloud base measurements made during polar darkness when there are few other influences on cloud formation, University of Reading meteorologists Professor Giles Harrison and Dr Maarten Ambaum found evidence for the first time that cloud heights are closely linked to the Carnegie curve.

"What we found was remarkable. The variations from both north and south poles are almost identical, suggesting a strong link with the Carnegie curve, when other factors are taken out of the equation. This may arise from charging of small droplets in the cloud's base, encouraging them to stick together," Professor Harrison said.

"This implies that factors inside or outside the climate system which change the global electric current, such as ocean temperatures or cosmic rays, may influence the properties of layer clouds. However our results say nothing about any long-term effects, as they were found for rapidly-occurring changes from hour to hour."

Layer clouds are particularly relevant to global temperatures. At night they act like a warm blanket, preventing heat from being lost from the earth into space, and during the day help cool the surface by reflecting away the sun's energy.

"The realisation the electrical heartbeat of the planet plays a role in the formation of layer clouds indicates that existing models for clouds and climate are still missing potentially important components," said Dr Ambaum.

"Understanding these missing elements is crucial to improve the accuracy of our weather forecasts and predicting changes to our climate. The climate system keeps on surprising us with its immense complexity and richness."

The findings are published in the journal Environmental Research Letters.

Something Mysteriously Warms Antarctica Ice
Very rapid climate changes take place on Antarctica. "Something" mysteriously warms Antarctica Ice and it's a dangerous process. The huge 18-mile-long crack that was discovered at the end of last year, is still growing and it remains unclear what is causing the sudden change in temperature. Antarctica is getting warmer and the melting of ice is adding to global sea level rise.

Geological Rift That Baffles Scientists Is Still Expanding
This huge rift can be clearly seen from space. Geologists are truly surprised at how fast it developed, when a 60 meter long rift opened up in Ethiopia.
It occurred in the course of a few days, in 2005 and the rift is still expanding.

Fastest Wind Ever Coming From A Disk Around Stellar-Mass Black Hole Discovered
This record breaking wind is moving about 20 million miles per hour - about 3% the speed of light and may be carrying away much more material than the black hole is actually capturing. This is nearly ten times faster than had ever been seen from a stellar-mass black hole, and matches some of the fastest winds g enerated by supermassive black holes, objects millions or billions of times more massive.

Extremely Distant And Exotic Quasar
It is an exotic and distant object, which has a velocity of recession of approximately 270,000 kilometers per second (!) or - 91 percent of the velocity of light itself.
The results show that this quasar, known as Q1442+101, is among exotic objects receding from the Milky Way at tremendous velocities of thousands and occasionally even hundreds of thousands of kilometers per second!

20,000-Solar-Mass Black Hole Found At The Core Of A Now-Destroyed Dwarf Galaxy
The formation of stellar-mass black holes through the collapse of massive stars is well accepted. However, it is not yet completely clear how the supermassive objects are formed.
They may form through the merger of smaller, intermediate-mass black holes (IMBHs) weighing hundreds to thousands of suns.

The "Cloaked" Star Was Difficult To Find
An object obscured by dust, and buried in a two-star system enshrouded by dense gas, is not easy to find.
A "cloaked" star was discovered after it ate a little of its neighbor. The meal must have given the star a bit of indigestion, because it "burped" with a blast of high-energy radiation, which gave it away.

This alien intruder from another galaxy is in many ways different from other exoplanets observed by astronomers.
