Latest Solar cycle Stories
In a breakthrough that will help scientists unlock mysteries of the sun and its impacts on Earth, scientists have created the first-ever comprehensive computer model of sunspots.
The sun is in the pits of a century-class solar minimum, and sunspots have been puzzlingly scarce for more than two years. Now, for the first time, solar physicists might understand why.
An international panel of experts led by NOAA and sponsored by NASA has released a new prediction for the next solar cycle.
A US-sponsored study suggests scientists expect a below average number of sunspots between now and 2013, when Solar Cycle 24 will peak.
The sun may soon begin moving into a more active period for sunspots, although forecasters predict it will be a fairly mild outbreak.
How low can it go? The Sun is plunging into the deepest solar minimum in nearly a century.
After two-plus years of few sunspots, even fewer solar flares, and a generally eerie calm, the sun is finally showing signs of life.
Scientists using NASAâ€™s RHESSI spacecraft have measured the roundness of the sun with unprecedented precision. They find that it is not a perfect sphere.
Astronomers who count sunspots have announced that 2008 has become the "blankest year" of the Space Age. Sunspot counts are at a 50-year low, signifying a deep minimum in the 11-year cycle of solar activity.
Data from the Ulysses spacecraft, a joint NASA-European Space Agency mission, show the sun has reduced its output of solar wind to the lowest levels since accurate readings became available. The sun's current state could reduce the natural shielding that envelops our solar system.
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...
