Latest Solar cycle Stories
Newly released data from the Curiosity rover indicate that Martian radiation levels are very close to being acceptable for future manned missions to the surface of the Red Planet.
A newly-released NASA visualization shows the process of the sun’s magnetic field changing polarity, with the positive and negative poles switching throughout the course of the 22 year magnetic solar cycle.
Maintaining a record of solar measurements is important in understanding the sun's effect on Earth and the National Oceanic and Atmospheric Administration's (NOAA), Total solar irradiance Calibration Transfer Experiment, or TCTE, is now providing that information.
Adding on to a series of solar flares throughout October and November, the sun emitted another significant solar flare on Nov. 19, 2013, peaking at 5:26 a.m. EST.
Two large, complex sunspots are moving across the face of the sun.
The sun emitted a significant solar flare that peaked at 1:14 a.m. EST on Nov. 10, 2013.
The sun emitted a significant solar flare – its fourth X-class flare since Oct. 23, 2013 -- peaking at 5:54 p.m. on Oct. 29, 2013.
Our sun, the bright yellow disk that sits at the center of the Solar System providing us with light, energy and warmth, has a much darker side that also has the potential to disrupt, rather than preserve, life on Earth.
Another solar flare erupted from the same area of the sun on Oct. 25, 2013,which peaked at 11:03 a.m. EDT. This flare is classified as an X2.1 class.
The sun emitted a mid-level solar flare that peaked at 8:30 pm EDT on Oct. 23, 2013.
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...
