The season for spotting Noctilucent Clouds or the "night-shining" clouds has begun, NASA said in a statement in early July.
Noctilucent Clouds are composed of tiny ice crystals 40 to 100 nanometers wide, which is just the right size to scatter blue wavelengths of sunlight, a NASA scientist explained.
According to NASA, the best time and location to search for these breathtakingly beautiful phenomenon would be between mid-May and the end of August in the northern hemisphere.
However, with no explanation yet found, these glowing, mystical clouds have been seen even as far south as Utah and Oregon and Denver, Colorado in the recent years.
Noctilucent Clouds were first observed in 19th century but their appearance has increased over time and are seasonal, appearing most often in late spring and summer every year.
NASA's AIM (Aeronomy of Ice in the Mesosphere) satellite, which was launched in 2007, continues to study the clouds, while scientists strive to know if noctilucent clouds signal climate change.
"They were a high-latitude phenomenon, but in recent years, AIM has spotted the clouds appearing ever lower in latitudes, but just why is not yet known," NASA said.Noctilucent Clouds first appeared in the nineteenth century, the era of Industrial Revolution; they are spreading in the recent years, which has puzzled scientists to the possible connection of the clouds with weather and climate, it added.
As this "beautiful mystery" refuses to unravel itself, check out some of the startling pictures from Noctilucent Clouds season 2011:

Comment: Let us suggest a reason for why instances of noctilucent clouds are increasing and intensifying.
What we suspect has been happening, based on our research thus far, is that
the upper atmosphere is cooling because it is being loaded with comet dust, which shows up in the form of
noctilucent clouds and other upper atmospheric formations.
Magnificent and mesmerizing noctilucent clouds (also called polar mesospheric clouds), were once considered to be rare. But now they are puzzling scientists with their
recent dramatic changes. Apparently, the clouds are growing brighter, are seen more frequently, are visible at ever lower latitudes and are now appearing even during the day. If scientists were allowed to conduct honest interdisciplinary research, such changes wouldn't be a mystery.
They would be able to figure out that comet dust is
electrically-charged which is causing the earth's rotation to slow marginally. The slowing of the rotation is reducing the magnetic field, opening earth to more dangerous cosmic radiation
and stimulating more volcanism. The volcanism under the sea is heating the sea water which is
heating the lower atmosphere and loading it with moisture.
The moisture hits the cooler upper atmosphere and contributes to a deadly mix that inevitably leads to an Ice Age, preceded for a short period by a rapid increase of greenhouse gases and "hot pockets" in the lower atmosphere, heavy rains, hail, snow, and floods.
Well that sounds like what we are seeing now.Is a ice age coming?If so how violent will the change be?Will we in the northern part of the country freeze to death before we know what hits us?Or will it just be an abrupt change that won't stop?Will we wake up to find ourselves buried in snow with no way out?
Should we move to the southern regions of the country or will it really matter where we live? I am just thinking of trying to survive this change before it happens?I wonder how much notice if any we will have?Questions,questions,questions?????Of course the govt will never tell us the truth on this.
If there is a Ice Age coming will it be like the snowball earth it wont matter where you live.I still think the equatorial region would be the safest area to live(unless the earth tilts)for a while longer.
So does anybody else have perhaps some more nfo on this?
