Measurements made by the Ulysses deep space probe, which was launched in 1990 to orbit the sun, have shown that the pressure created inside the heliosphere by the solar wind has been decreasing.

Dr David McComas, principal investigator on the IBEX mission, said: "It is a fascinating interaction that our sun has with the galaxy surrounding us. This million mile an hour wind inflates this protective bubble that keeps us safe from intergalactic cosmic rays.

"With less pressure on the inside, the interaction at the boundaries becomes weaker and the heliosphere as a whole gets smaller."

If the heliosphere continues to weaken, scientists fear that the amount of cosmic radiation reaching the inner parts of our solar system, including Earth, will increase.

This could result in growing levels of disruption to electrical equipment, damage satellites and potentially even harm life on Earth.

I'm afraid that before this hits the people we're gonna get hit by the global warming which is melting the ice a lot faster than projected and has the snowball effect.

I believe the weather works in hot and cold cycles and has done so for many years. Nature has some pretty powerful ways of looking after itself.

UPDATE: After having done my research, I can now say that what I originally posted was completely and entirely false. I still wouldn't worry about personal safety, but those cosmic rays can apparently be pretty bad for satellites.


Still, it would take a very long time for anything to happen-- plenty enough time to start putting more shielding on our satellites.

Did anyone else think that this thread was about OpenOffice.org and how there were problems with Sun Microsystems? :)

Heh. Well, at least OpenOffice is safe!

Thank god Open Office is safe. :)

I was also thinking about the other "Sun"

I tend to ignore these sort of things...Because honestly...next they'll want us to start worrying that the sun is going to die in 5billion years. I think its time we all started preparing..I have..Have you!?

On a side note- i love astronomy, sci-fi, and all things space in general so its not just my ineptitude for the above statement =)

ditto.

Face it, by the time a lot of these things have happened, we'll have made a mess of the Earth and the rich will have climbed into space ships and are interstellar nomads while the poor(er) are stuck here trying to fix the world.

I think he was referring to Sun Microsystems, but maybe that's just me...

Does this mean I won't be getting any cool Mr. Fantastic super-stretchy super power?

Dammit.
