Comet ISON shines brightly in this image taken on the morning of Nov. 19, 2013. This is a 10-second exposure taken with the Marshall Space Flight Center 20" telescope in New Mexico. The camera there is black and white, but the smaller field of view allows for a better "zoom in" on the comet's coma, which is essentially the head of the comet.

Comet ISON shines in this five-minute exposure taken at NASA's Marshall Space Flight Center on Nov. 8 at 5:40 a.m. EST. The image has a field of view of roughly 1.5 degrees by 1 degree and was captured using a color CCD camera attached to a 14" telescope located at Marshall. At the time of this picture, Comet ISON was 97 million miles from Earth, heading toward a close encounter with the sun on Nov. 28. Located in the constellation of Virgo, it is now visible in a good pair of binoculars. Image credit: NASA/MSFC/Aaron Kingery

An X1.0-class flare exploded off the right side of the sun, peaking at 10:03 p.m. EDT on Oct. 27, 2013. This image was captured by NASA's Solar Dynamics Observatory in the 131 Angstrom wavelength, which is particularly good for showing solar flares and is typically colorized in teal. Credit: NASA/SDO
