The Solar Dynamics Observatory captures an image of an enormous solar prominence around the sun. To put this in perspective, Bad Astronomy points out that the Earth would appear about 5 pixels by comparison. (Our image is slightly smaller, meaning you could barely see the Earth on this scale.) The prominence is estimated to be 434,960 miles across.
