Two views of Comet Ison from NASA's SOHO spacecraft show the comet is fading dramatically. (Source: ESA/NASA, annotations by Karl Battams) | Update 10 a.m. MST: I've added a spectacular video to the bottom of this post showing Comet ISON streaking toward the sun. It's from NASA's SOHO spacecraft. | We're just a few hours from Comet ISON's closest approach to the sun, and the news is not encouraging: The sungrazer has gotten dramatically dimmer, according to Karl Battams of the Comet ISON Observing Campaign.
