Sun Emits Mid Level Solar Flare Jan. 7, 2014
2014-01-07 12:11:43

NASA The sun emitted a mid-level solar flare, peaking at 5:13 a.m. EST on Jan. 7, 2014. Images of the flare were captured by NASA's Solar Dynamics Observatory and showed that it came from an active region on the sun that currently sports one of the largest sunspots seen in the last 10 years. Sunspots are regions of strong and complex magnetic fields on the sun's surface. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere...

As ice storms put much of Ontario into the cold and dark for Christmas, Friends of Science are citing a recent report by Dr. Madhav Khandekar that indicates cold weather extremes are on the rise; this trend is under reported in the media, and virtually unnoticed by climate researchers at the IPCC. Friends of Science say the sun is the main driver of climate change, not carbon dioxide, and that solar cycles are exhibiting abnormal patterns. Calgary, Alberta, Canada (PRWEB) December 26,...

Mars Surface Radiation Suitable Manned Mission
2013-12-10 15:24:46

Brett Smith for redOrbit.com - Your Universe Online Newly released data from the Curiosity rover indicate that Martian radiation levels are very close to being acceptable for future manned missions to the surface of the Red Planet. While the Curiosity rover spent its first 300 days cruising around the planet’s Gale Crater gathering soil samples and examining rock structures, the onboard Radiation Assessment Detector (RAD) was making detailed recording of the radiation found on the...

Magnetic Field Lines

[ Watch the Video: The Sun's Changing Magnetic Field ] redOrbit Staff & Wire Reports - Your Universe Online A newly-released NASA visualization shows the process of the sun’s magnetic field changing polarity, with the positive and negative poles switching throughout the course of the 22 year magnetic solar cycle. According to Karen C. Fox of the Goddard Space Flight Center, the magenta colored lines represent regions where the overall field is negative, while the green lines...

New Instrument Continues To Gather Effects Of The Sun On Earth
2013-12-05 15:56:22

NASA Maintaining a record of solar measurements is important in understanding the sun's effect on Earth and the National Oceanic and Atmospheric Administration's (NOAA), Total solar irradiance Calibration Transfer Experiment, or TCTE, is now providing that information. Many natural conditions on Earth such as the surface temperature or air temperature depend on energy that comes from the sun in the form of electromagnetic radiation. A solar cycle lasts about 11 years and typically has...

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,...

Sunspots Moving Across The Sun
2013-11-14 14:28:37

[ Watch The Video: Sputtering Spot – The Last Days of AR11890 ] NASA Two large, complex sunspots are moving across the face of the sun. One, which produced considerable solar activity in the past weeks, has almost rotated off completely. A new sunspot rounded into view on Nov. 11, 2013 and is now making its way across the Earth-side of the sun. An active region can contain one or more sunspots. The National Oceanic and Atmospheric Administration numbers active regions consecutively as...

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,...

Is The Solar Maximum Peak Upon Us? Increase In Sun's Activity May Tell
2013-10-26 08:22:09

[ Watch the Video: Our Sun Is Flaring Up ] Lawrence LeBlond for redOrbit.com - Your Universe Online Our sun, the bright yellow disk that sits at the center of the Solar System providing us with light, energy and warmth, has a much darker side that also has the potential to disrupt, rather than preserve, life on Earth. Experts know that the sun goes through a natural solar cycle about every 11 years, marked by an increase and decrease of sunspots – visible blemishes that appear on...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
