Latest Solar cycle Stories
NASA’s dramatic video of a black-topped sun on the verge of flipping its magnetic polarity has captivated people.
Solar experts are anticipating a major event to happen within the next three or four months - the sun is going to flip.
Crew members aboard the International Space Station had to add a little more distance between the orbiting laboratory and Earth on Sunday for a science experiment.
The sun emitted a mid-level solar flare, peaking at 6:49 p.m. on June 7, 2013.
As the peak year of the solar maximum picks up in intensity, NASA’s Solar Dynamics Observatory (SDO) observed yet another solar flare and two coronal mass ejections (CMEs) mid-week.
On May 17, the sun unleashed an Earth-directed coronal mass ejection (CME) at 5:24 a.m. EDT sending billions of tons of solar particles into space. The matter from this CME will likely reach Earth in one to three days and potentially affect electronic systems in satellites and on the ground.
Solar activity continued on May 14, 2013, as the sun emitted a fourth X-class flare from its upper left limb, peaking at 9:48 p.m. EDT.
Given a legitimate need to protect Earth from the most intense forms of space weather -- great bursts of electromagnetic energy and particles that can sometimes stream from the sun -- some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible.
On Sunday (May 12) the Sun emitted a significant solar flare that is being classified as the first X-class solar flare of 2013. The X1.7 flare, which peaked at about 10 p.m. EDT, was also associated with another solar event known as a coronal mass ejection (CME).
NASA has released a video of the unbroken coverage of the sun for the past three years, taken by its Solar Dynamics Observatory.
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...
