Latest Solar cycle Stories
WASHINGTON, March 2, 2011 /PRNewswire-USNewswire/ -- NASA-sponsored research has resulted in the first computer model that explains the recent period of decreased solar activity during the sun's 11-year cycle.
Researchers today provided the first computer model explaining the recent period of decreased solar activity during the Sun's 11-year cycle.
A $28 million University of Colorado Boulder instrument developed to study changes in the sun's brightness and its impact on Earth's climate is one of two primary payloads on NASA's Glory mission set to launch from Vandenberg Air Force Base in California on Feb. 23.
A surge of charged plasma particles from a massive solar eruption has brushed off the Earth's northern pole, producing auroras and disrupting some radio communications, according to NASA scientists.
Earthâ€™s climate continues to change at a rapid pace.
Scientists have taken a major step toward accurately determining the amount of energy that the sun provides to Earth, and how variations in that energy may contribute to climate change.
Scientists are determining the properties of materials inside the sun in order to prevent solar damage to high tech systems.
Two satellite instruments aboard NASA's Solar Radiation & Climate Experiment (SORCE) mission -- the Total Solar Irradiance Monitor (TIM) and the Solar Irradiance Monitor (SIM) -- have made daily measurements of the sun's brightness since 2003.
Nine years after beginning its unprecedented look at the gateway between Earth's environment and space, not to mention collecting more data on the upper atmosphere than any other satellite, NASAâ€™s Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) mission has been extended again.
After detailed analysis of data from the SOHO and GOES spacecraft, a team of European scientists has been able to shed new light on the role of solar flares in the total output of radiation from our nearest star.
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...
