Using NASA’s Van Allen Probes, new research reveals that the Van Allen radiation belts contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth.
The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They can wax and wane in response to incoming energy from the sun, sometimes swelling up enough to expose satellites in low-Earth orbit to damaging radiation. The discovery of the drain that acts as a barrier within the belts was made using NASA’s Van Allen Probes, launched in August 2012 to study the region. A paper on these results appeared in the November 27, 2014, issue of Nature magazine.
“This barrier for the ultra-fast electrons is a remarkable feature of the belts,” said Dan Baker, a space scientist at the University of Colorado in Boulder and first author of the paper. “We’re able to study it for the first time, because we never had such accurate measurements of these high-energy electrons before.”
Understanding what gives the radiation belts their shape and what can affect the way they swell or shrink helps scientists predict the onset of those changes. Such predictions can help scientists protect satellites in the area from the radiation.
The Van Allen belts were the first discovery of the space age, measured with the launch of a US satellite, Explorer 1, in 1958. In the decades since, scientists have learned that the size of the two belts can change – or merge, or even separate into three belts occasionally. But generally the inner belt stretches from 400 to 6,000 miles above Earth’s surface and the outer belt stretches from 8,400 to 36,000 miles above Earth’s surface…

“Good thing for NASA the Van Allen belts waned from 1969 thru 1972.”
Lol.

“This may explain why we never sent a Chimpanzee through the Van Allen Belts. “
We sent humans!
That’s been in the news lately - usually with the caveat that only nonalcoholic muscadine ‘wine’ was used in the study.
WWCKD?
(What would captain Kirk do)
Moronic equivalency.
Comparing charged particle radiation with gamma radiation.
Do you realize light is also radiation? So do you live in the dark to avoid ‘dangerous’ radiation?
Did you hide from your television set as a child? That was illuminated by Van Allen Belt-type charged particle radiation.
Putin Troll. Get outta here with your KGB Disinformation and Demoralization campaign.
I only know what Kirk would do if a woman was involved…
“That was posted here, and its wine with the alcohol removed.
What’s the point?…”
If the alcohol is removed it can’t be labeled wine. Muscadine Wine is about 10% alcohol.
Anthropomorphic Belt Change! Our fault, buy an EV!
More proof that God took great care during the creation to protect and to position the Earth. Yet another demonstration that Creation is rational.
Apollo went through them quickly on the way to the moon. It’s just not a good idea to have a spaceship orbiting at that altitude for too long.
Another factor that makes Earth what it is and that is often ignored when claiming some body orbiting some star is “Earth like”.
All the factors that make Earth “Earth like” are necessary for life on Eath being as it is, and without which it is questionable if life on Earth would exist.
Another proof that God designed Earth to be protected from outside destructive forces, like Cosmic Rays............
There are thousands of photographs, taken from space - from orbit, from the moon, and even of course of the earth, from the moon. You think those are fake?
It boggles the mind. Interestingly enough, there are space nerds who have done the Math - you can take their word for it, a given photograph of the earth taken from the lunar surface on a specific day, at a specific hour, they can calculate what portion of the globe should be visible, the continents.
Guess what. They coincide perfectly. Imagine that! Every single one. Even less surprising therefore, so does the cloud cover. That’s right boys and girls, even the clouds observed match the cloud formations photographed from weather satellites that day.

Be careful—don’t want the Russkies poisoning your precious bodily fluids.
;-)
Look up the article if you want.
I am not going to engage in a debate on this.
I will provide the links that provide the strongest arguments I have seen—you can read them or not as you choose.
Love it.
Seaman Kowalski will save us!
