Planetary transits of the Sun by Mercury and Venus don't come along very often, and when they do we make a big deal of it because, well, it's really cool!

Comet ISON captivated our world, and many of our world’s robotic emissaries for many months. But, alas, poor ISON is dead -- again. Here I wrap up our enthusiastic coverage of this multi-morphing zombie comet that tried to survive and re-survive as it came within one solar diameter of the Sun.

Comet ISON reached perihelion at 18:25 UT (10:25 PT) on November 28. It's an event that's was watched around the world, accompanied by tons of commentary and streams of photos. We will update this blog entry periodically with links to all the resources that we hear of for following the comet's progress.

Two Hangouts bookended comet ISON's perihelion, hosted by Chuck Beuter of Comet Festival South Bend. On November 25, it was I and Ron Kaitchuck. On December 2, Alex Filippenko and I discussed what happened to the comet over Thanksgiving.

When comet ISON passed through perihelion last week, solar observing spacecraft had a ringside view. Here are several animations of ISON's perilous passage from the SOHO and two STEREO spacecraft.

Comet ISON has entered the field of view of the STEREO HI-1A camera, and, in an awesome animation, it joins a large cast of characters already present there.

IRIS, the Interface Region Imaging Spectrograph spacecraft, was launched from Orbital Science Corporation's Stargazer carrier aircraft over the Pacific Ocean at 7:27 p.m PDT.

No mission to Europa, diminished funding for outer planets missions, a small bump to small spacecraft missions, and an increase for asteroid detection are part of the White House's proposal for NASA in 2014.

Comet PANSTARRS is delighting northern hemisphere viewers right now. But it's also big, bright, and beautiful to the STEREO spacecraft.

Curiosity has been shooting photos of the Sun as Phobos and Deimos cross its face, and -- as far as I can tell -- captured sunspots as well.
