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...

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...

Solar Activity Continues On The Sun
2013-05-15 11:28:59

NASA Solar activity continued on May 14, 2013, as the sun emitted a fourth X-class flare from its upper left limb, peaking at 9:48 p.m. EDT. This flare is classified as an X1.2 flare and it is the 18th X-class flare of the current solar cycle. The flare caused a radio blackout — categorized as an R3, or strong, on NOAA´s space weather scales from R1 to R5 -- which has since subsided. The flare was also associated with a non-Earth-directed CME. CMEs and flares are separate but...

The Impacts Of Strong Solar Flares
2013-05-14 07:53:54

NASA Given a legitimate need to protect Earth from the most intense forms of space weather -- great bursts of electromagnetic energy and particles that can sometimes stream from the sun -- some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible. Solar activity is indeed currently ramping up toward what is known as solar maximum, something that occurs approximately every 11 years. However, this same solar cycle...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
