Latest Solar cycle Stories
Space physicists from the University of Leicester are part of an international team that has identified the impact of the Sun on Mars' atmosphere.
In today's issue of Science, NASA solar physicist David Hathaway reports that the top of the sun's Great Conveyor Belt has been running at record-high speeds for the past five years.
The Solar Dynamics Observatory will observe the sun faster, deeper, and in greater detail than previous observatories, breaking barriers of time-scale and clarity that have long blocked progress in solar physics.
A $32 million University of Colorado at Boulder instrument package set for launch Feb. 9 by NASA should help scientists better understand the violent effects of the sun on near-Earth space weather that can affect satellites, power grids, ground communications systems and even astronauts and aircraft crews.
On August 1, 2008 a total solar eclipse was visible within a narrow corridor that traversed from North America to China.
Every 11 years, the sun undergoes a furious upheaval, a flamboyant display of stellar power.
Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun's impact on Earth over the course of the 11-year solar cycle.
The sun is in the pits of the deepest solar minimum in nearly a century. Weeks and sometimes whole months go by without even a single tiny sunspot. The quiet has dragged out for more than two years, prompting some observers to wonder, are sunspots disappearing?
Researchers from NCAR have created the first-ever model to simulate the impact of the sunâ€™s radiation fluctuations on the earthâ€™s climate.
Subtle connections between the 11-year-solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research results appearing this week in the journal Science.
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...
