Latest Solar cycle Stories
Large changes in the sun's energy output may drive fluctuations in Earth's outer atmosphere.
Large changes in the sun's energy output may drive unexpectedly dramatic fluctuations in Earth's outer atmosphere.
By monitoring the star's sound waves, the team has observed a magnetic cycle analogous to the Sun's solar cycle.
Why sunspots are a strong source of radio emissions and what information those emissions carry will be the focus of an invited talk by NJIT Research Professor Jeongwoo Lee tomorrow at the International Astronomical Union Symposium on the Physics of Sun and Star Spots in Ventura, CA.
A new analysis of the unusually long solar cycle that ended in 2008 suggests that one reason for the long cycle could be a stretching of a current of plasma that circulates between the Sunâ€™s equator and its poles.
High above Earth's surface where the atmosphere meets space, a rarefied layer of gas called "the thermosphere" recently collapsed and now is rebounding again.
After the most profound lull in solar activity for nearly a century, the Sun is finally coming back to life.
Scientists are learning to predict giant solar storms that could, at any time, hit the Earth and produce cascading catastrophes.
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.
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...
