You can find the image on Flickr. On August 31, 2012 a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth's magnetic ...

I'm posting these images as a supplement @Hobbes's accepted answer and @TildalWave's comments (which includes links to these images). I started reading some of those links. The gallery is a good starting place but there are different tabs to check out. The values 171 and 304 represent the central wavelengths used, in Angstrom units. Our visible spectrum is ...

The video is significantly sped up (videos of the Sun generally are sped up). CMEs move at an average speed closer to 500 km/s. That's why when we see the activity we generally have a warning of up to a few days before the CME gets to where we are. If the CME was moving at the speed of light, it would hit us as we saw it happen (a little more than eight ...

OK I'll bite, despite that Dean Pesnell of the SDO team must really love me by now. :) Most of the info you're after is available on SDO Data pages, if you click on the info icon. Also note that the Fe (Iron) channel composite in your question is equipped with color-keyed channel info bottom left of it, tho it is rather difficult to see at the resolution ...

The composite image cannot be made from our standard jpegs as they are log-scaled to improve the contrast. You put the linearly-scaled data into the color channels of an sRBG image and then log scale the result. The AIA instrument filters are multi-layer metallic filters deposited on glass mirrors that were ground to the right shape. All is explained in ...

2012rcampion found a nice paper detailing all the visual effects caused by the optical system of the satellite. According to the paper, the many small artifacts are caused by diffraction: The optical setup of each AIA telescope is characterized by structures with uniform wire meshes used to support the thin filters that create the EUV passbands. ...
