Sun spots might appear small and innocent, but they hint at powerful forces at work on the surface of the Sun, forces that can wreak havoc on our electronic devices when they cause solar flares and coronal mass ejections.
08 October 2012, 10:21 AM ET
A wave of solar particles from the sun may amp up the northern lights displays on Earth Monday night (Oct. 8).
05 October 2012, 04:14 PM ET
Painterly auroras occur when charged particles from the sun get caught in our planets magnetic field and pulled down near one of our poles. The variety of colors are the result of different electromagnetic reactions with oxygen and nitrogen.
04 October 2012, 02:40 PM ET
Far from Earth and the inner solar system two massive gas giants patrol the outer reaches of our solar system; Uranus knocked on its axis and Neptune, wrapped in a cobalt blue atmosphere of inexplicably fast winds.
01 October 2012, 11:10 AM ET
NASA's Radiation Belt Storm Probes mission (RBSP) captured radio waves emitted by energetic particles in the magnetosphere. The 'chorus' phenomenon is well known by scientists and is also known as 'Earthsong'.

By far the most massive planet in our solar system, Jupiter features giant hurricanes, auroras, abstract artistic cloudswirls, and maybe even a solid core. It also protects Earth by gravitationally clearing the solar system of asteroids and comets.

Northern Lights photographer Chad Blakely (lightsoverlapland.com) captured amazing imagery over Abisko National Park on Sept. 19th, 2012. He told his Facebook audience: 'After tonight there is no doubt in my mind that the solar maximum has arrived'
20 September 2012, 07:59 PM ET
Energetic particles in the magnetosphere emit radio waves that are audible to humans. The NASA Radiation Belt Storm Probes mission's (RBSP) instrumentation captured an instance of the event. The 'chorus' phenomenon is well known by scientists.

Researchers are zeroing in on these mysterious, croissant-shaped solar structures.
20 September 2012, 01:32 PM ET
The fall equinox marks changing seasons this weekend, with a chance of seeing auroras.
18 September 2012, 06:35 PM ET
The peak in solar activity is predicted for early to mid 2013. The space-based X-Ray Telescope (XRT) aka Hinode mission has been fixated on the Sun for years and the increase in activity is truly stunning.
12 September 2012, 05:51 PM ET
See amazing photos of auroras taken in September 2012.
07 September 2012, 07:00 AM ET
A string-like line of plasma was ejected from the sun Aug. 31.
06 September 2012, 12:15 PM ET
NASA's Solar Dynamic Observatory (SDO) caught a M1.6 flare erupting from the sun just as the probe's eclipse season begins. For the month of September, the Earth will cross the SDO's line of sight, creating eclipses like the one in the video.

29 August 2012, 05:36 PM ET
A series of coronal mass ejections (CMEs) resembling a light bulb erupted from the sun on August 20, 2012. The only question is, what was the sun's big idea?
29 August 2012, 05:00 PM ET
The rounded coronal mass ejection was released by the sun on Aug. 20, 2012.
25 August 2012, 05:49 AM ET
