Meteor Smoke Makes Strange Clouds - Imbedded in Noctilucent Clouds

Anyone who's ever seen a noctilucent cloud or "NLC" would agree: They look alien. The electric-blue ripples and pale tendrils of NLCs reaching across the night sky resemble something from another world. Researchers say that's not far off. A key ingredient for the mysterious clouds comes from outer space.

"We've detected bits of 'meteor smoke' imbedded in noctilucent clouds," reports James Russell of Hampton University, principal investigator of NASA's AIM mission to study the phenomenon. "This discovery supports the theory that meteor dust is the nucleating agent around which NLCs form."

Spectacular Noctilucent Clouds Photographed Over Iceland

A bank of electric-blue noctiluent clouds swept across Iceland on August 2nd, producing a vivid display of luminous ripples and tendrils over Reykjavik:

"These are the highest clouds in Earth's atmosphere, located at altitudes of around 76 to 85 kilometres," says photographer Iurie Belegurschi. "It was a beautiful display."

New data from NASA's AIM spacecraft prove that noctilucent clouds (NLCs) are seeded by space dust. The tiny ice crystals that NLCs are made of nucleate around "meteor smoke" wafting through the upper reaches of Earth's atmosphere. Not only do these clouds look alien, they really are alien. A new video from NASA explains the research.

Noctilucent Clouds observed in Poland as they continue Southward advance

This morning a vast bank of electric-blue noctilucent clouds rippled across northern Europe. "It was like water in the sky," says Barbara Grudzinska, who photographed the display from Warsaw, Poland:

"These are the first noctilucent clouds this year so clearly visible at our latitude in Warsaw (52 N)," says Grudzinska.

When NLCs first appeared in the 19th century, the mysterious clouds were confined to the Arctic, most often seen in the same places as Northern Lights. In recent years, however, their "habitat" has been expanding, rippling as far south as Colorado, Virginia, Kansas, and Utah. (Here are some examples of sightings in the lower United States.) There is growing evidence that the expansion is a sign of climate change, although this remains controversial.

Whatever the reason, noctilucent clouds aren't just at high latitudes anymore, so sky watchers everywhere should be alert for them.

Observing tips:


Look west 30 to 60 minutes after sunset when the sun has dipped 6o to 16o below the horizon. If you see luminous blue-white tendrils spreading across the sky, you've probably spotted a noctilucent cloud.

Comment: Indeed, something is 'up'...

Aurora Surprise Over Canada

July 9th began with a brief but beautiful display of auroras over North America. "I had gone out to search for noctilucent clouds, but instead I found these Northern Lights," says Robert Snache of Rama First Nation, Ontario:

The source of the display was not an explosion on the sun, but rather a fluctuation in the interplanetary magnetic field (IMF). The IMF near Earth tipped south, briefly opening a crack in our planet's magnetosphere. Solar wind poured in and ignited the lights.

More auroras could be in the offing. A CME that left the sun on July 6th might deliver a glancing blow to Earth's magnetic field on July 9-10. NOAA forecasters estimate a 25% to 30% chance of polar geomagnetic storms if and when the cloud arrives.

Electric Blue Noctilucent Clouds Seen From Scotland

Last night, 82 km above Earth's surface where our planet's atmosphere meets the vacuum of space, a ray of sunlight hit a wispy, rippling bank of icy noctilucent clouds (NLCs). They lit up, glowing electric-blue, producing this apparition over Queensferry, Scotland:

"A stitch of 2 images shows the broad extent of the display last night," says photographer Adrian Maricic. "It was bright and vivid, the best of the 2012 noctilucent cloud season so far for us in Scotland!"

Normally confined to Arctic latitudes, the intense NLCs of June 24-25, 2012, dipped all the way down to the south coast of England: "This was my first sighting of 2012," says Pete Lawrence, who photographed the southern edge of the bank from Selsey UK.

As Seen From Antarctica, Halo Appears Around the Moon

In the icy lands around the south pole, ordinary things take on an exotic quality. Count moon haloes among them. On April 5th, Sam Burrell photographed this specimen rising above the Brunt Ice Shelf in Antarctica:

"Around midnight, the air on the Brunt Ice Shelf the air was filled with diamond dust," says Burrell. "As the moon rose, we caught this show."

Diamond dust is the atmospheric optics term for tiny, jewel-like crystals of ice. They form on cold days in the air near ground level. When they catch the rays of the low-hanging sun or moon, the results can be spectacular. "In this single display, we could see a moon halo, moondogs, and hints of a moon pillar," says Burrell.

Iceland: A Noctilucent Masterpiece Over Reykjavíc

Night-shining "noctilucent" clouds create a magical glow in the night skies over Reykjavíc, Iceland in this beautiful photo by Örvar Atli Þorgeirsson, taken on August 6. In the foreground is "The Sun Voyager" (Sólfar), an iconic steel sculpture located on the city waterfront representing a Viking ship.

Örvar did not set out to photograph this rare atmospheric phenomenon but had instead intended to shoot aurora triggered by recent solar outbursts.

"The forecast on the 6th of August was predicting extreme aurora activity," Örvar says in his Flickr description. "Even though it was very early August and the night would not get fully dark I went out as the aurora can be seen in deep twilight conditions. I saw the aurora for 1 - 2 minutes that night. I did not get a good picture of it though. Instead we witnessed this even rarer phenomenon called noctilucent clouds."

Noctilucent Clouds Sighted From Germany!

"The morning of July 26th was electric blue!" says Heiko Ulbricht of Freital, Saxony, Germany. "I woke up at 3 clock, looked out my bedroom window to the north and saw a stunning display of noctilucent clouds." Moments later, he dashed outside with a camera to record the view:

July has been an odd time for noctilucent clouds (NLCs). The month began with an extravagant display that stretched as far south as Colorado and Kansas--odd because NLCs are usually confined to higher latitudes. The event seemed to herald a period of widespread sightings. Observers were disappointed, though, when the clouds quickly retreated to their usual northern habitat. Could this German apparition signal renewed activity? Sky watchers at all latitudes should be alert for electric-blue ripples around sunrise and sunset. Observing tips may be found in the gallery.

Best of the Web: The Harbingers of Change Can Now Be Seen All Around the World! Mysterious Noctilucent Clouds Brighten Up Night Skies

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.

Comment: For the possible explanation, read the comment at the end of the article.

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.

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.
