Earth's Shrinking Atmosphere Baffles Scientists. An increase in CO2 could be one reason why a layer of Earth's upper atmosphere went through its biggest contraction in 43 years.

Earth's Shrinking Atmosphere Baffles Scientists

Earth's thermosphere went through its biggest contraction in 43 years. Researchers expected to see a contraction due to a solar minimum, but not this significant. One explanation may be an increase in carbon dioxide in the atmosphere. Scientists are mulling over why part of the Earth's atmosphere recently suffered its biggest collapse since records began, and is only now starting to rebound. The collapse occurred in a region known as the thermosphere, a rarefied layer of the planet's upper atmosphere between 90 and 600 kilometers (56 to 373 miles) above the surface, which shields us from the sun's far and extreme ultra violet (EUV) radiation. A report in Geophysical Research Letters by a team led by John Emmert from the United States Naval Research Laboratory has found that the thermosphere went through its biggest contraction in 43 years.

Spectacular Russian rocket launch - more evidence of comet dust loading our atmosphere. Earlier today SOTT posted this video of a rocket launch cum 'UFO spiral'.

The person who uploaded it to YouTube managed to convince him or herself that the spectacular display was the result of UFOs "taking over control of the rocket" once it reached a certain altitude. Well I've since located other videos of the launch minus the misleading text and the "blinking lights" (which appear to have been added later for effect, if not for outright disinformation purposes).

Here is a YouTube video entitled 'Launch of the Soyuz 2 rocket carrying Glonass-K satellite': No blinking lights surrounding the rocket and no text to tell you it's aliens from another planet taking remote control of it either. Here's another video of the launch, this time amateur footage taken from another location. At around 2:04', its exhaust trail begins to light up: I'm sorry to disappoint the True Believers out there but that is not an "Alien Sky Torch"! Amazing Photo: 'Fire Rainbow' Over South Florida.

So-called "fire rainbows" are neither on fire nor are they rainbows, but they sure are stunning. They are technically known as iridescent clouds, a relatively rare phenomenon caused by clouds of water droplets of nearly uniform size, according to a release by NASA. These clouds diffract, or bend, light in a similar manner, which separates out light into different wavelengths, or colors.

That makes them similar to rainbow-colored glories, which are also formed by diffraction, and also produce an oscillating pattern of colors ranging from blue to green to red to purple and back to blue again. Although iridescent clouds have rainbow-like colors, the way light is scattered to produce them is slightly different. As with other iridescent objects, like peacock feathers, the color changes depending upon one's position relative to the sun and the object.

Hundreds of people stepped out of their offices to take pictures of the celestial wonders. Onlookers believed it was signs of the last days. "Jesus is coming today," fascinated Victoria Mintah told AfricaNews. However, meteorologists said the phenomenon known as halo phenomenon is natural around the world. It is already a subject of interest on social networks. "God is wonderful have u seen de sky people. "Solar halo is wats happenin in de sky," she asked. "Really i doubt if its a rainbow ,just one of the antics of God, definately we will get the scientific definition for it," Princess Anna-Marian Ayeley Ardayfio commented on someone's status.

A halo also known as a nimbus, icebow or Gloriole is an optical phenomenon produced by ice crystals creating colored or white arcs and spots in the sky.

High above Earth's surface where the atmosphere meets space, a rarefied layer of gas called "the thermosphere" recently collapsed and now is rebounding again. Earth's Upper Atmosphere Cooling Dramatically. SAN FRANCISCO ?

Earth's Upper Atmosphere Cooling Dramatically

When the sun is relatively inactive ? As it has been in recent years ? The outermost layer of Earth's atmosphere cools dramatically, new observations find. The results could help scientists better understand the swelling and shrinking of our planet's atmosphere, a phenomenon that affects the orbits of satellites and space junk. The data, from NASA's TIMED mission, show that Earth's thermosphere (the layer above 62 miles or 100 km above the Earth's surface) "responds quite dramatically to the effects of the 11-year solar cycle," Stan Solomon of the National Center for Atmospheric Research in Boulder, Colo., said here this week at the annual meeting of the American Geophysical Union.
