  • An active region on the sun emitted a mid-level solar flare, peaking at 4:47 a.m. EST on Nov. 5, 2014. This is the second mid-level flare from the same active region, labeled AR 12205, which rotated over the left limb of the sun on Nov. 3. The image was captured by NASA’s Solar Dynamics Observatory (SDO) in extreme ultraviolet light

  • This near-infrared, color mosaic from NASA’s Cassini spacecraft shows the sun glinting off of Titan’s north polar seas. While Cassini has captured, separately, views of the polar seas (see PIA17470) and the sun glinting off of them (see PIA12481 and PIA18433) in the past, this is the first time both have been seen together in the same view. The sunglint,

  • NASA SDO Image: Jack-o-Lantern Sun Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The image was captured by NASA’s Solar Dynamics Observatory, or SDO, which watches the sun at all times from its orbit in space. The active regions in this image appear brighter because those are areas that emit more
