Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun’s activity, known as solar maximum, is a time of numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space.

On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT. NASA's Solar Dynamics Observatory captured images of the flare, which erupted on the left side of the sun.

As children, we are told never to look directly at the Sun, especially through the lens of a camera, telescope or magnifying glass. To fully understand our star, scientists must use spacecraft that can observe this invisible light before it is absorbed by the atmosphere.

NASA’s STEREO mission began in 2006 and has been providing scientists with images from the far side of the sun since February 2011. The spacecraft duo that were placed in orbit around the sun are now about to embark on the next phase of their mission.

Sun Has Bad Weather Just Like On Earth
2014-06-26 03:31:08

Just like on Earth, the Sun has spells of bad weather, with high winds and showers of rain. But unlike the all-too-frequent storms of the UK and Ireland, rain on the Sun is made of electrically charged gas (plasma) and falls at around 200,000 kilometers an hour from the outer solar atmosphere, the corona, to the Sun's surface.

A suite of Sun-gazing spacecraft, SOHO, STEREO and Solar Dynamics Observatory (SDO), have spotted an unusual series of eruptions in which a series of fast 'puffs' force the slow ejection of a massive burst of plasma from the Sun's corona.
