Latest Solar minimum Stories
If you've ever stood in front of a hot stove, watching a pot of water and waiting impatiently for it to boil, you know what it feels like to be a solar physicist.
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.
NASA has rescheduled a media teleconference for 2 pm EST on Wednesday, March 2, to discuss the first computer model that explains the recent period of decreased solar activity during the sun's 11-year cycle.
Scientists are determining the properties of materials inside the sun in order to prevent solar damage to high tech systems.
The aurora borealis, or Northern Lights, have dwindled in the last five years, becoming more rare than at any other time in the last hundred years, said the Finnish Meteorological Institute on Tuesday.
Large changes in the sun's energy output may drive unexpectedly dramatic fluctuations in Earth's outer atmosphere.
Scientists are learning to predict giant solar storms that could, at any time, hit the Earth and produce cascading catastrophes.
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.
A new iPhone app developed by NASA-supported programmers delivers a live global view of the sun directly to your cell phone.
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...
Sunspot -- A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings, and intense magnetic activity. Although they are blindingly bright, at temperatures of roughly 5000 Kelvin, the contrast with the surrounding material at some 6000 Kelvin leaves them clearly visible as dark spots. Interestingly, if they were isolated from the surrounding photosphere they would be brighter than an electric arc. History Apparent references...
