Dank je, en je hebt gelijk. Het is idd vermoeiend om steeds weer tegen dezelfde mensen met dezelfde leugens/halve waarheden/foute redenaties/misleidingen aan te praten. Het is hier op fok praktisch altijd hetzelfde kliekje dat zich er schuldig aan maakt. Ook in dit topic weer.quote:Op vrijdag 13 april 2007 13:15 schreef wortels het volgende:

Tenzij je gelooft dat je als mens zijnde iets van deze straling gaat merken en/of je het niet meteen eens bent met het wetenschappelijke idee dat alle straling buiten de deur wordt gehouden door onze atmosfeer.

Naar mijn idee is de Zon ook de enigste reden voor de opwarming van de Aarde. Zou eens mooi zijn als dat voor eens en altijd bewezen werd.
Door de... Klimaatinquisitie! Het linkse ecoterrorisme wil ons goed laten voelen, want we zijn zo moreel superieur, en samen met de communisten proberen ze ons wijs te maken dat de mensheid iets van doen heeft met zogenaamde "global warming".quote:Op zaterdag 14 april 2007 14:45 schreef whosvegas het volgende:

Bron : Reuters
A three-dimensional image of the sun released by NASA's Solar TErrestrial RElations Observatory (STEREO) on April 24, 2007.
WASHINGTON (Reuters) - The first three-dimensional images of the Sun from a pair of spacecraft orbiting the planet were released on Monday and can begin helping scientists predict when and how hard dangerous solar storms will hit, the U.S. space agency NASA said.
Such storms can disrupt satellites, communications and sometimes the electricity supply, and may endanger astronauts in Earth orbit as well as commercial airline flights.
The twin Solar Terrestrial Relations Observatory, or STEREO, satellites can create more accurate, real-time views of these storms, called coronal mass ejections, project scientists said.
"The improvement with STEREO's 3-D view is like going from a regular X-ray to a 3-D CAT scan in the medical field," said Michael Kaiser, STEREO Project Scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
The STEREO spacecraft were launched in October and have now been maneuvered into their orbits, one slightly ahead of Earth and one slightly behind.
"Just as the slight offset between a person's eyes provides depth perception, the separation of spacecraft allow 3-D images of the sun," NASA said in a statement.
Solar storms are a conglomeration of charged gases and magnetic forces. When they hit the Earth's magnetic barrier they cause the auroras, the dramatic Northern and Southern lights.
But they can also disrupt satellites, radio communication, and power grids. The radiation they carry is a danger to astronauts.
The orbiting SOHO observatory is providing some information, but the two STEREO spacecraft will be able to triangulate with SOHO and give a much better view of these bursts as they bud off the sun's surface, NASA said.
"In the solar atmosphere, there are no clues to help us judge distance. Everything appears flat in the 2-D plane of the sky. Having a stereo perspective just makes it so much easier," said Russell Howard of the Naval Research Laboratory.
"Knowing where the front of the coronal mass ejection cloud is will improve estimates of the arrival time from within a day or so to just a few hours," Howard added.
"STEREO also will help forecasters estimate how severe the resulting magnetic storm will be."

A new study from the National Academy of Sciences outlines grim possibilities on Earth for a worst-case scenario solar storm.
Damage to power grids and other communications systems could be catastrophic, the scientists conclude, with effects leading to a potential loss of governmental control of the situation.
The prediction is based in part on major solar storm in 1859 caused telegraph wires to short out in the United States and Europe, igniting widespread fires.
It was perhaps the worst in the past 200 years, according to the new study, and with the advent of modern power grids and satellites, much more is at risk.
"A contemporary repetition of the [1859] event would cause significantly more extensive (and possibly catastrophic) social and economic disruptions," the researchers conclude.
When the sun is in the active phase of its 11-year cycle, it can unleash powerful magnetic storms that disable satellites, threaten astronaut safety, and even disrupt communication systems on Earth.
The worst storms can knock out power grids by inducing currents that melt transformers.
Modern power grids are so interconnected that a big space storm — the type expected to occur about once a century — could cause a cascade of failures that would sweep across the United States, cutting power to 130 million people or more in this country alone, the new report concludes.
Such widespread power outages, though expected to be a rare possibility, would affect other vital systems.
"Impacts would be felt on interdependent infrastructures with, for example, potable water distribution affected within several hours; perishable foods and medications lost in 12-24 hours; immediate or eventual loss of heating/air conditioning, sewage disposal, phone service, transportation, fuel resupply and so on," the report states.
Outages could take months to fix, the researchers say. Banks might close, and trade with other countries might halt.
"Emergency services would be strained, and command and control might be lost," write the researchers, led by Daniel Baker, director of the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder.
"Whether it is terrestrial catastrophes or extreme space weather incidents, the results can be devastating to modern societies that depend in a myriad of ways on advanced technological systems," Baker said in a statement released with the report.
Stormy past
Solar storms have had significant effects in modern time:
— In 1989, the sun unleashed a tempest that knocked out power to all of Quebec, Canada.
— A remarkable 2003 rampage included 10 major solar flares over a two-week period, knocking out two Earth-orbiting satellites and crippling an instrument aboard a Mars orbiter.
"Obviously, the sun is Earth's life blood," said Richard Fisher, director of the Heliophysics division at NASA. "To mitigate possible public safety issues, it is vital that we better understand extreme space weather events caused by the sun's activity."
"Space weather can produce solar storm electromagnetic fields that induce extreme currents in wires, disrupting power lines, causing wide-spread blackouts and affecting communication cables that support the Internet," the report states. "Severe space weather also produces solar energetic particles and the dislocation of the Earth's radiation belts, which can damage satellites used for commercial communications, global positioning and weather forecasting."
Rush to prepare
The race is on for better forecasting abilities, as the next peak in solar activity is expected to come around 2012.
While the sun is in a lull now, activity can flare up at any moment, and severe space weather — how severe, nobody knows — will ramp up a year or two before the peak.
Some scientists expect the next peak to bring more severe events than other recent peaks.
"A catastrophic failure of commercial and government infrastructure in space and on the ground can be mitigated through raising public awareness, improving vulnerable infrastructure and developing advanced forecasting capabilities," the report states. "Without preventive actions or plans, the trend of increased dependency on modern space-weather sensitive assets could make society more vulnerable in the future."
The report was commissioned and funded by NASA. Experts from around the world in industry, government and academia participated. It was released this week.
