Another treatment of a fiery Coronal Mass Ejection (CME) with stunning, bright details in the ejected material. In this composite image, an EIT image of the Sun in extreme UV light, taken on January 4, 2002, was enlarged and superimposed on LASCO C2. In coronagraph images, direct sunlight is blocked by an occulter (covered by the Sun here) to reveal the surrounding faint corona.

Wait, is the sphere the sun, and the swirl the ejected material?? The apparent volume ratio is extremely confusing :(

ReplyDeleteThe stuff coming out looks bigger because, in simple terms the sun is more compressed. Its like filling a balloon from a tank of compressed gas. You can blow a balloon much bigger than the container the gas came out of because it expands as it is released.
ReplyDeleteThis is a composite image made from combining the photos captured by two separate instruments, one quick capture type device which captures the detail of the sphere of the sun which is overlaid on the image of the corona in which the sphere of the sun is blocked by an occultation disk in order to capture the more faint corona while not being blinded by the sphere of the sun...i hope this helps understand what you are looking at
