Noctilucent Clouds Observed By NASA Sounding Rocket
2013-04-04 14:55:35

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...

Powerful Coronal Mass Ejection Erupts On Sun's Earth-Facing Side
2013-03-15 13:42:58

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful solar eruption occurred on the surface of the sun at 2:54 a.m. (EDT) this morning. The eruption, called a coronal mass ejection (CME), occurred on the Earth-facing side of the sun and may have released billions of tons of solar particles into space racing their way toward Earth, potentially making impact within three days. Once particles from this CME event hit Earth, electrical systems in orbit, in the sky and on...

Sun Erupts With Two CMEs In One Day
2013-03-14 14:15:10

Brett Smith for redOrbit.com - Your Universe Online Earlier this week the sun twice ejected large amounts of solar material during two coronal mass ejections (CMEs) in a 12-hour period, according to a NASA report. The CMEs are not expected to significantly impact Earth. The first CME began at 8:36 p.m. EDT on March 12, 2013. The solar material was directed toward three NASA spacecraft, Spitzer, Kepler and Epoxi. Two of the crafts, Spitzer and Kepler, are in an Earth-like orbit around...

New Satellite Will Provide Earlier Storm Warnings And Space Weather Predictions
2013-03-03 06:04:44

[ Watch the Video: Talking Tornadoes with Tim Samaras ] Alan McStravick for redOrbit.com - Your Universe Online On December 26, 2004, we learned of the importance that early warning systems can play in preventing loss of life when the great Indonesian tsunami caught locals and vacationers alike by surprise. In contrast, on March 11, 2011, the early warning system, while unable to prevent tens of thousands of human casualties, was effectively responsible for preventing a greater loss of...

Van Allen Probes Discover New Radiation Belt, Possibly Due To Solar Storm
2013-02-28 14:59:50

Lee Rannals for redOrbit.com — Your Universe Online NASA announced that its Van Allen Probes have led to a revision of a 50-year-old theory about the Earth's radiation belts. The Van Allen radiation belts surrounding Earth were thought to be just two giant swaths of radiation, first discovered in 1958. More than a half-century later, NASA launched twin probes (August 30, 2012) to create a detailed map of the region and catalogue a variety of energies and particles in these...

Densest Artificial Ionospheric Plasma Clouds Produced Using HAARP
2013-02-26 10:34:33

U.S. Naval Research Laboratory U.S. Naval Research Laboratory research physicists and engineers from the Plasma Physics Division, working at the High-frequency Active Auroral Research Program (HAARP) transmitter facility, Gakona, Alaska, successfully produced a sustained high density plasma cloud in Earth's upper atmosphere. "Previous artificial plasma density clouds have lifetimes of only ten minutes or less," said Paul Bernhardt, Ph.D., NRL Space Use and Plasma Section. "This higher...

Mysterious Math Of The Solar Wind Deciphered By NASA
2013-02-22 14:27:36

NASA Many areas of scientific research -- Earth's weather, ocean currents, the outpouring of magnetic energy from the sun -- require mapping out the large scale features of a complex system and its intricate details simultaneously. Describing such systems accurately, relies on numerous kinds of input, beginning with observations of the system, incorporating mathematical equations to approximate those observations, running computer simulations to attempt to replicate observations, and...

Flare, Ejection And Rain All Caught In Spectacular Solar Show
2013-02-20 15:40:05

[Watch Video: Fiery Looping Rain On The Sun] Lee Rannals for redOrbit.com — Your Universe Online An eruption on the sun can be a beautiful, monstrous event, and NASA's Solar Dynamics Observatory (SDO) has helped to bring these dangerous, yet breathtaking events right to our computer screens. On July 19, 2012, the sun erupted in a solar flare, ejecting material called a coronal mass ejection (CME), creating a loop in the sun's atmosphere known as the corona. This moderately...

Understanding The Magnetosphere Better Than Ever With Help From THEMIS
2013-02-20 10:47:18

NASA On Earth, scientists can observe weather patterns, and more importantly can predict them, through the use of tens of thousands of weather observatories scattered around the globe. Up in the space surrounding Earth -- a space that seethes with its own space weather made of speeding charged particles and constantly changing magnetic fields that can impact satellites — there are only a handful of spacecraft to watch for solar and magnetic storms. The number of observatories has...
