Comet ISON is inching ever closer to the Sun, and it'll get incredibly close later on today. In the meantime, though, you can watch its most recent progress in this video from NASA.

In the early hours of Nov. 27, 2013, Comet ISON entered the field of view of the European Space Agency/NASA Solar and Heliospheric Observatory. In this picture, called a coronagraph, the bright light of the sun itself is blocked so the structures around it are visible. The comet is seen in the lower right; a giant cloud of solar material, called a coronal mass ejection or CME, is seen billowing out under the sun.

Updated: Sad news, folks. Like Icarus, it seems comet ISON's visit brought it a little too close to our sun, causing it to burn up and mostly disintegrate today. Several sources are reporting the death of the comet, which means the only thing you'll see in the night skies this December are maybe a few snowflakes. But it's not all sad news. According to NASA, as the broken up comet slingshots around the sun, it will give scientists a great opportunity to study what's inside ISON and what it's made of. So there's definitely still reason for giving thanks today.
