Scientists Have No Idea What's Up With the Sun
Posted by Lev/Christopher on April 22, 2009 at 6:38am in Science & Technology
Last October, the Telegraph reported:
The protective shield of energy that surrounds our solar system, has weakened by 25 per cent over the past decade and is now at it lowest level since the space race began 50 years ago.
Scientists are baffled at what could be causing the barrier to shrink in this way and are to launch mission to study the heliosphere.
Today, BBC is reporting:
The Sun is the dimmest it has been for nearly a century.
There are no sunspots, very few solar flares - and our nearest star is the quietest it has been for a very long time.
The observations are baffling astronomers, who are due to study new pictures of the Sun, taken from space, at the UK National Astronomy Meeting.
The Sun normally undergoes an 11-year cycle of activity. At its peak, it has a tumultuous boiling atmosphere that spits out flares and planet-sized chunks of super-hot gas. This is followed by a calmer period.
Last year, it was expected that it would have been hotting up after a quiet spell. But instead it hit a 50-year year low in solar wind pressure, a 55-year low in radio emissions, and a 100-year low in sunspot activity.
According to Prof Louise Hara of University College London, it is unclear why this is happening or when the Sun is likely to become more active again...
No-one knows how the centuries-long waxing and waning of the Sun works.
The bottom line is that scientists really have no idea what's up with the sun.
There's a lot we don't understand about our galactic neighborhood, either.

This site below helps explain how it all works and demonstrates why NASA and cosmologists find mysteries around every corner.

Nobody has an idea? Who are we kidding?
We are approaching a time point when the Earth, the Sun and the enormous black hole in the center of the Milky Way galaxy are perfectly aligned. This happens once in every 5000 plus years. The next happening will be on the day of winter solstice 2012.
Why we can expect some new phenomena to be visible? The old and new theories and speculation including the new one from NASA explaining the existence of 5 moving gravity "wells" around the orbit of the earth can be found on http://www.galacticwind.com/ClimateChange/index.htm and the Future timeline on this site.

Actually it's all a hoax. Chemtrails are cooling the earth and 'they' are using the 'cooling' sun as the excuse because they fear the global anarchy that will prevail when the people find out that they are all likely to die soon. It was a couple of years ago that there were stories floating about concerning the sudden lack of access to observatories worldwide and unless you have that access how can you choose to believe this nonsense after all the other lies we have been told? Google "Hughes' patent for aluminized clouds" - there you will find all the ends of the threads.
