New Program Aims To Understand Effects Of Space Weather
2013-07-01 19:10:36

Lee Rannals for redOrbit.com -- Your Universe Online Scientists are working on a program to better understand how national grids could be affected by space weather. British Geological Survey (BGS) researchers are conducting continuous measurements of the background electric field in the UK to better understand how the UK National Grid can be interrupted by the Sun. Space weather can take place when the ejection of material from the Sun, or coronal mass ejection (CME), shoots towards...

Solar Corona Captured In New Hi-C Images
2013-07-01 04:40:35

[ Watch the Video: Stunning New Solar Atmosphere Images Could Help Solve Longstanding Mysteries ] redOrbit Staff & Wire Reports - Your Universe Online Thanks to an innovative new camera on board a sounding rocket, an international team of scientists has managed to capture pictures of the sun's outer atmosphere that are five times sharper than any previous images. The images, which were scheduled to be presented by University of Central Lancashire professor Robert Walsh at the...

Five Year Anniversary Of Stereo Imaging For NASA's TWINS
2013-06-23 04:12:37

redOrbit Staff & Wire Reports - Your Universe Online This month marks the fifth anniversary of NASA’s Two Wide-angle Imaging Neutral-atom Spectrometers (TWINS) missions, which are stereoscopically imaging the mysterious and dynamic region surrounding Earth known as the magnetosphere, the US space agency announced on Saturday. The TWINS A & B probes were launched on June 15, 2008, and according to NASA, since that time they have been orbiting in widely separated planes so that...

Moon Radiation Study Reduce Health Risks Astronauts
2013-06-12 10:23:11

April Flowers for redOrbit.com - Your Universe Online A new study from the space scientists at the University of New Hampshire (UNH) and the Southwest Research Institute (SwRI) reports that data collected by NASA's Lunar Reconnaissance Orbiter (LRO) reveals that lighter materials like plastics provide effective shielding against the radiation hazards faced by astronauts during extended space travel. The findings, published in the journal Space Weather, could help reduce human health risks...

M5.9 Solar Flare Emitted By The Sun
2013-06-11 09:18:19

NASA The sun emitted a mid-level solar flare, peaking at 6:49 p.m. on June 7, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours. This flare is classified as an...

WASHINGTON, May 31, 2013 /PRNewswire-USNewswire/ -- NASA Administrator Charles Bolden will deliver the keynote address at the annual Space Weather Enterprise Forum Tuesday, June 4, at the National Oceanic and Atmospheric Administration Auditorium and Science Center, located at 1301 East-West Highway in Silver Spring, Md. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Media representatives are invited to attend the forum, which will focus on the impact of space weather events...

Magnetic Field Model Of Sun Explains Solar Activity Cycles
2013-05-23 08:32:58

April Flowers for redOrbit.com - Your Universe Online Since the 18th Century, scientists have been aware that the Sun oscillates between periods of high and low solar activity in an 11-year cycle. So far, though, they have been unable to fully explain how this cycle is generated. Understanding the Sun´s magnetic activity has become increasingly important as we rely more on our electronic devices. Changes in the magnetic field are responsible for “space weather”...

M-Class Solar Flare And Two Coronal Mass Ejections Detected Mid-Week
2013-05-23 07:00:42

Lawrence LeBlond for redOrbit.com - Your Universe Online As the peak year of the solar maximum picks up in intensity, NASA´s Solar Dynamics Observatory (SDO) observed yet another solar flare and two coronal mass ejections (CMEs) mid-week. On Wednesday May 22 the sun emitted an M7 solar flare, which peaked at about 9:38 a.m. EDT. While it was not immediately clear if the M-class flare also produced a CME, NASA confirmed later that the flare was associated with a CME. While this CME...

NASA’s BARREL Mission Released 20 Balloons To Help Answer Question About Space Weather
2013-05-21 12:07:08

NASA In Antarctica in January, 2013 — the summer at the South Pole — scientists released 20 balloons, each eight stories tall, into the air to help answer an enduring space weather question: when the giant radiation belts surrounding Earth lose material, where do the extra particles actually go? The NASA-funded mission is called BARREL for Balloon Array for Radiation-belt Relativistic Electron Losses and is led by physicist Robyn Millan of Dartmouth College in Hanover, N.H....

Coronal Mass Ejection Heads Toward Earth This Weekend
2013-05-19 07:37:21

[WATCH VIDEO: Coronal Mass Ejection On May 17, 2013] Lawrence LeBlond for redOrbit.com - Your Universe Online On May 17, the sun unleashed an Earth-directed coronal mass ejection (CME) at 5:24 a.m. EDT sending billions of tons of solar particles into space. The matter from this CME will likely reach Earth in one to three days and potentially affect electronic systems in satellites and possibly the International Space Station (ISS). NASA research models based on observations from...
