Sun's protective 'bubble' is shrinking

Dear Mr. Felix,

I am regularly looking at your very interesting website. You are completely right in criticism of the global warming hoax and in pointing to the influence of the sun. Good work!

Did you see the article in the Telegraph on the shrinking heliosphere of the sun? Please find the link below.

Beste regards,

                                 Sun's protective 'bubble' is shrinking

19 Oct 08 - The protective shield of energy that surrounds our solar system and helps shield the Earth from harmful interstellar radiation, has weakened by 25 per cent over the past decade.

Scientists are baffled at what could be causing the barrier to shrink in this way and are to launch a mission to study the heliosphere.

"There is a very high energy galactic radiation that is dangerous to living things,” said Dr Nathan Schwadron, co-investigator on the IBEX (Interstellar Boundary Explorer) mission at Boston University

"Around 90 per cent of the galactic cosmic radiation is deflected by our heliosphere, so the boundary protects us from this harsh galactic environment."

The heliosphere is created by the solar wind, a combination of electrically charged particles and magnetic fields that emanate at more than a million miles an hour from the sun, meet the intergalactic gas that fills the gaps in space between solar systems.

At the boundary where they meet a shock wave is formed that deflects interstellar radiation around the solar system as it travels through the galaxy.

Without the heliosphere the harmful intergalactic cosmic radiation would make life on Earth almost impossible by destroying DNA and making the climate uninhabitable.

               Depending on how much we are subjected to, this "harmful
               intergalactic cosmic radiation" could also lead to evolutionary
               leaps - the true origin of species.
