Sun Emits Another X-Class Solar Flare
2013-11-19 11:53:37

NASA Adding on to a series of solar flares throughout October and November, the sun emitted another significant solar flare on Nov. 19, 2013, peaking at 5:26 a.m. EST. 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 GPS and communications signals travel. To see how this event may impact Earth,...

Radiation Hazards Of Deep Space Travel Quantified By Researchers
2013-11-19 09:06:48

April Flowers for redOrbit.com - Your Universe Online Comprehensive findings on space-based radiation as measured by a detector aboard NASA’s Lunar Reconnaissance Orbiter (LRO) have been published by a team of scientists led by the University of New Hampshire. The findings, published in a special edition of Space Weather, provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars. The findings...

Sun Emits Seventh Significant Flare Since Oct. 23, 2013
2013-11-11 07:51:25

NASA The sun emitted a significant solar flare that peaked at 1:14 a.m. EST on Nov. 10, 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 GPS and communications signals travel. To see how this event may impact Earth, please visit NOAA's Space Weather Prediction Center at...

Sun Produces Fourth X-class Flare In A Week
2013-10-30 11:04:01

NASA The sun emitted a significant solar flare – its fourth X-class flare since Oct. 23, 2013 -- peaking at 5:54 p.m. on Oct. 29, 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 GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing,...

Recalling The 2003 Nightmare Halloween Magnetic Storm
2013-10-30 08:32:39

[ Watch the Video: Is There Space Weather In Store For Trick-Or-Treaters? ] Lawrence LeBlond for redOrbit.com - Your Universe Online As Halloween approaches, most people are thinking about costume parties, tricks and treats, haunted hayrides and perhaps a rogue werewolf running amok. But for scientists, this October 31 may provide a scare much different from what most kids get when they go Trick-or-Treating this All Hallow's Eve. The NOAA/NWS Space Weather Prediction Center on...

Sun Continues To Produce Solar Flares
2013-10-28 11:08:45

NASA After emitting its first significant solar flares since June 2013 earlier in the week, the sun continued to produce mid-level and significant solar flares on Oct. 27 and Oct. 28, 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 GPS and communications signals travel. To see how...

Space Weather Impacts Pilots And Airline Passengers
2013-10-27 06:19:50

[ Watch the Video: Pilots And Passengers Absorb Cosmic Rays And Radiation ] redOrbit Staff & Wire Reports - Your Universe Online Thanks to space weather, airline pilots absorb approximately as much radiation over the course of a year as a nuclear power plant employee, NASA officials revealed on Friday. In fact, according to the US space agency, pilots are classified as “occupational radiation workers” by the Federal Aviation Administration (FAA) because they fly at heights...

Third Solar Flare Emitted By The Sun In Two Days
2013-10-25 12:12:19

NASA [ Watch The Video: Experimental NASA Research Model of Path for Oct. 22-23 CMEs ] The M9.4 flare on Oct. 23, 2013, was associated with a coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Another solar flare erupted from the same area...

NASA's SDO Captures Image Of Mid-level Solar Flare
2013-10-24 12:46:59

NASA The sun emitted a mid-level solar flare that peaked at 8:30 pm EDT on Oct. 23, 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 GPS and communications signals travel. Such radiation can disrupt radio signals for as long as the flare is ongoing, anywhere from minutes to hours. To see...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
