Comet ISON - called by some the "comet of the century" made its way around the sun tonight, but we aren't sure if it survived the trip or not. What happened to the chunk of rock and ice determines how bright it will be in the night sky during December.
This image from NASA's Solar Dynamics Observatory shows the sun, but no Comet ISON was seen. A white plus sign shows where the Comet should have appeared. It is likely that the comet did not survive the trip.
Here's a GIF of the comet making its way into the sun's corona, you can see it flare up and dim as it rounds the sun. That makes the researchers at NASA think it has broken up, and probably won't be visible in December:
