Cloud glowing strange in the night

The glowing nocturnal clouds at night often appear in the extreme recently observed further south, to the United States.

Exotic glowing cloud in the night

According to UPI, the ground observer and AIM spacecraft (Aeronomy of Ice in the Mesosphere) of the US Aerospace Agency (NASA) discovered noctilucent clouds, or "glowing clouds". at night ", on US territory on June 10.

After the AIM space probe recorded data on noctilucent clouds, scientists created a composite image of their presence, like they were seen from outer space. Clouds appear in different shades from light blue to white, depending on the density of the ice particles inside the cloud.

Polar glowing clouds form in spring and summer. The high-floor atmosphere has a low temperature, causing steam to condense and freeze around microscopic dust particles such as meteor dust and other particles that act as "nuclei ". When ice crystals accumulate enough, we can observe many bright blue and bright white clouds.

AIM space exploration ship charted the appearance of glowing clouds at night for many years. The data obtained show that noctilucent clouds are appearing earlier, more frequently and at lower latitudes. Some scientists believe that the phenomenon is the result of increased greenhouse gas emissions.

Noctilucent clouds were first recorded in the mid-1800s, after the Krakatau volcanic eruption in Indonesia spread a lot of ash into the atmosphere. Even when the ash settles, researchers continue to observe this phenomenon.
