Earth's Star Shaped Gamma Rays

Quote for the day:

"In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move."

Awoke around 3:00 a.m. - watched the moon set, the stars disappear and the sun rise on a beautiful crisp spring morning in the valley. No donkey braying (the farm alarm) across the valley means the cougars and coyotes have departed for now.

A week ago it was unseasonably warm and now that spring has officially arrived it is below zero and there is a new drop of snow on the mountains all around this morning. Thank goodness the freezing level stayed high enough that it did not hit the newly forming buds on the trees and plants. The weather sure isn’t what is used to be.

After wandering the usual morning links – quite a lot of solar flares, volcanic activity and earthquake activity lately – came across an excellent photo of our earth through gamma-ray vision. Found the star shaped energy fascinating as I awoke from the heat of one branded on my palm many years ago & it has turned to 2 stars since then. It appears to be a growing phenomenon among a few people I know personally…sure wonder what it is all about…. wouldn’t anyone?

“A NASA-funded scientist has produced a new type of picture of the Earth from space, which complements the familiar image of our "blue marble". This new picture is the first detailed image of our planet radiating gamma rays, a type of light that is millions to billions of times more energetic than visible light.

The image portrays how the Earth is constantly bombarded by particles from space. These particles, called cosmic rays, hit our atmosphere and produce the gamma-ray light high above the Earth. The atmosphere blocks harmful cosmic rays and other high-energy radiation from reaching us on the Earth's surface.

The red image indicates lower gamma-ray energy levels, with the green version corresponding to higher levels and the blue image showing the highest energy levels of all. The fourth image (lower right) is a composite of all four panels together.”

Just imagine how these incredible invisible rays affect all life forms on this planet!
