Is our shield from the outside universe lowering? what could this mean for us?




The heliosphere is the big magnetic bubble in space carved out by the solar wind. The solar defines the border between our Solar System and interstellar space. This border, called the heliopause, is where the solar wind's strength is no longer great enough to push back the wind originating from other stars. The region around the heliopause also acts as a shield for our Solar System, warding off a significant portion of the cosmic rays outside the galaxy. Latest data from Ulysses show that the Sun has reduced its output of solar wind to the lowest levels since accurate readings have become available. This current state of the Sun could reduce the natural shielding that envelops our Solar System.....

..."Galactic cosmic rays carry with them radiation from other parts of our galaxy," said Ed Smith, NASA's Ulysses Project Scientist from the Jet Propulsion Laboratory in California, USA. "With the solar wind at an all-time low, there is an excellent chance that the heliosphere will diminish in size and strength. If that occurs, more galactic cosmic rays will make it into the inner part of our Solar System."

Galactic cosmic rays are of great interest; cosmic rays are linked to engineering decisions for unmanned interplanetary spacecraft and exposure limits for astronauts traveling beyond low-Earth orbit. .....

If there is less, sunspots won't the earth be cooler? Thus more ice in the upper atmosphere, maybe this could act as a deflector/absorber of the radiation.....Radioactive snow! ahhh!

I blame it on cern

But also, it might not just be the sun responsible for the magnetic feild, other planets have a magnectic feild. Maybe the revolving, planets, pushing and pulling on the sun is at an all time low.

The position of the planets in relative to eachother, may have a differant effect on the sun, creating an altogher high or low gravitational pull on the sun.

I doubt many will get much sleep after that happens due to cosmic rays zipping through their skulls.:


Since the Apollo Moon missions in the 1960s and 1970s, astronauts have reported curious ‘flashes of light’ even when they have their eyes closed. It is thought that this is caused by cosmic rays passing through the eye and either producing a flash of light in the eye or triggering a nerve response in the retina.


This could be a boon for the pharmaceutical industry!

It is true the solar winds are at the lowest ever since we began measuring in the 60s, but on the 22/9/08 some activity on the sun ie sunspot which could be the end of the solar minimum and the beggining of a solar maximum, this is still only speculation as in the next solar max but if its anything to go by records it looks promising.

Isn't there an 11 year cycle for sun spots? Would you happen to know what part we're on?

Here is a thread I posted earlier it has info regarding the recent sunspot

There is a cycle, and we are coming to the end of it, apparently. But the fact that they can map it, means that there must be a regular outside influence. Like what i said in my before post.

Go to Nasa.gov. It shows a new sunspot. The begining of the 24th cycle since they started measuring about 400 years ago. Well, not NASA.

Thought I'd "bump" this thread - the media has picked up on this and are playing it as a doomsday scenario:

www.smh.com.au...


If the heliosphere continues to weaken, it is feared intergalactic cosmic radiation reaching Earth will increase, disrupting electrical equipment, damaging satellites and potentially harming life.


Oh noes!

www.telegraph.co.uk...


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.


Apparently the heliosphere has shrunk 25% in the past decade - which actually corresponds to the Sun's solar cycle.

This report came out a month ago, as the the OP's post shows, but today it's been picked up and sensationalized.



If the heliosphere contracted or disappeared so regularly, obviously the Earth and Sun have mechanisms for dealing with it, or evolution wouldn't have gained a foothold.

As long as there's a Sun, there should definitely always be a heliosphere.

I wouldn't be so sure.

Scientists are NOT sure, too. Things may became too weird
