NASA's AIM Mission Unlocks The Secrets Of Noctilucent Clouds
2014-04-17 08:10:25

[ Watch the Video: Unexpected Teleconnections in Noctilucent Clouds ] April Flowers for redOrbit.com - Your Universe Online When you think about the North and South poles, they seem to be worlds apart. They are separated by four oceans, six continents, and more than 12,000 nautical miles. New data from NASA's Aeronomy of Ice in the Mesophere (AIM) spacecraft suggests, however, that they aren't as far apart as you might think. AIM has revealed "teleconnections" in the planet's...

Karen C. Fox, NASA's Goddard Space Flight Center First spotted in 1885, silvery blue clouds sometimes hover in the night sky near the poles, appearing to give off their own glowing light. Known as noctilucent clouds, this phenomenon began to be sighted at lower and lower latitudes -- between the 40th and 50th parallel -- during the 20th century, causing scientists to wonder if the region these clouds inhabit had indeed changed -- information that would tie in with understanding the weather...

NASA Developing Sodium Lidar To Help Examine Eartth’s Mesophere

Peter Suciu for redOrbit.com – Your Universe Online Future trips to space will be looking closely at sodium. Not as in the salt that astronauts use to flavor their food and can be brought to space in small packets. NASA scientists are instead looking at the sodium – the sixth most abundant element in Earth’s crust – that exists in the mesosphere. While sodium is already used as a coolant in nuclear power plants and can be used as a desiccant to remove humidity, it is also found...

Noctilucent Clouds Observed By NASA Sounding Rocket

NASA A constant stream of space debris flows toward Earth from the rest of the solar system. Large meteors can sometimes survive the intense friction and heat upon entering Earth´s atmosphere, but by and large the meteors evaporate and reform into tiny particles that are left to whiz through the atmosphere. Such particles are so light and so ubiquitous that scientists refer to them as smoke. Tracking how this smoke swirls around Earth has implications for understanding weather and...

High up in the sky near the poles some 50 miles above the ground, silvery blue clouds sometimes appear, shining brightly in the night. First noticed in 1885, these clouds are known as noctilucent, or "night shining," clouds. Their discovery spawned over a century of research into what conditions causes them to form and vary "“ questions that still tantalize scientists to this day. Since 2007, a NASA mission called Aeronomy of Ice in the Mesosphere (AIM) has shown that the cloud...

Nine years after beginning its unprecedented look at the gateway between Earth's environment and space, not to mention collecting more data on the upper atmosphere than any other satellite, NASA's Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) mission has been extended again. Before the launch of TIMED, the mesosphere and lower thermosphere/ionosphere -- which help protect us from harmful solar radiation -- had been one of the least explored and understood regions of our...

HAMPTON, Va., Dec. 16 /PRNewswire-USNewswire/ -- New measurements from a NASA satellite show a dramatic cooling in the upper atmosphere that correlates with the declining phase of the current solar cycle. For the first time, researchers can show a timely link between the Sun and the climate of Earth's thermosphere, the region above 100 km, an essential step in making accurate predictions of climate change in the high atmosphere.

U.S. scientists say research involving the exhaust plume from a NASA space shuttle launch suggests the 1908 Tunguska explosion was caused by a comet The mysterious explosion leveled 830 square miles of Siberian forest and a cause has never been determined. But Cornell University researchers say findings from their study indicated the explosion was nearly certainly caused by a comet entering the Earth's atmosphere. It's almost like putting together a 100-year-old murder mystery, said Professor...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
