Gigantic Gap In The Sun's North Pole -
Earth Is Inside A Solar Wind Stream Flowing From It

MessageToEagle.com - The European Space Agency/NASA Solar and Heliospheric Observatory, or SOHO, captured this image of a gigantic coronal hole hovering over the sun's north pole on July 18, 2013, at 9:06 a.m. EDT.

Coronal holes are dark, cold areas in the sun's outermost atmospheric layer.

They contain little solar material, have lower temperatures, and therefore, appear much darker than their surroundings.

They are the sources of solar winds -- streams of charged particles that travel at more than 1 million mph and can cause auroras and geomagnetic storms (worldwide disturbances of the Earth's magnetic field) when they reach the Earth.

Coronal holes are a typical feature on the sun, though they appear at different places and with more frequency at different times of the sun's activity cycle.

The activity cycle is currently ramping up toward what is known as solar maximum, currently predicted for late 2013.

During this portion of the cycle, the number of coronal holes decreases. During solar max, the magnetic fields on the sun reverse and new coronal holes appear near the poles with the opposite magnetic alignment.

The coronal holes then increase in size and number, extending further from the poles as the sun moves toward solar minimum again.

At such times, coronal holes have appeared that are even larger than this one.

The holes are important to our understanding of space weather, as they are the source of a high-speed wind of solar particles that streams off the sun some three times faster than the slower wind elsewhere.

While it's unclear what causes coronal holes, they correlate to areas on the sun where magnetic fields soar up and away, failing to loop back down to the surface, as they do elsewhere.

An extensive coronal hole has rotated into view over the past several days (July 13-18, 2013). It's one of the largest coronal holes we have seen in some time.

The magnetic field lines in a coronal hole extend out into the solar wind rather than coming back down to the Sun's surface as they do in other parts of the Sun. This image of particles heated to over 2 million degrees was taken in extreme UV light by SOHO.

The hotter the temperature, the more extended the features are in the outer solar atmosphere.

Millennia Old Astronomical Secret Revealed

In 1943, an ancient papyrus was bought by the Cairo museum. It was written in Hieratic and although portions of it were eaten away by ants, it was a very precious ancient document. The papyrus contained three separate books dealing with astronomy. One of the books was the Cairo Calendar, and now it reveals an ancient astronomical secret...

Most Alien World We Can Only Imagine

This is not an alien world, anyone of us will ever be able to visit. It's not very far away, only about 40 light years from Earth, but it circles dangerously close to a stellar inferno, completing one orbit in only 18 hours. The alien planet named "55 Cancri e" is 26 times closer to its parent star than Mercury is to the Sun. The temperature on the surface of 55 Cancri e is estimated to be as high as 2,700 degrees Celsius.

Solar Activity Causes Changes In Humans And Affects Our Health: Scientists Say

As our Sun goes through its 11-year cycle that is due to peak in 2013 or 2014, scientists worry about dangerous solar flares that could practically wipe out a lot of our electronic civilization. There has also bee concern in what way our Suns' abnormal behavior can effect human health. Some scientists say there is actually a correlation between the rise and fall of solar activity and the human consciousness...
