So if you wake up one morning and it's a particularly beautiful day, you'll know we made it. Okay, I'm signing out.posted by 2bucksplus at 3:50 PM on December 15, 2011 [7 favorites]

Today, a comet falls into the sun.
Well, more like "grazes the sun & evaporates"

That's not a comet, that's a Disaster Area concert.

This describes a crush I had in Grade 10 almost perfectly.

Note that you can actually watch a near realtime feed from NASA's SDO.

How does that feed work? It seems to repeat the same 25 frames again and again - does it load new frames eventually?

Refreshed, and it's up to 58 frames now. You can actually see the comet closing in on the sun now!

I see it! Open Ironmouth's link, then choose the 1024x1024 feed from the top wavelength over on the right (it's yellowish). Once that's loaded up, go to about frame 49 and start stepping through slowly.
There's a big solar prominence at about 9 o'clock on the Sun's disc - the comet fades into view just below that, and passes through it upwards and to the right, disappearing behind the sun by frame 70-odd. It's blink-and-you-'ll-miss-it stuff, but pretty cool nonetheless!

It almost seems like it just...evaporated. Should it do that?

And in a few short weeks the sun will start dividing, and a new star-child will form.

Oh, it only GRAZES the sun? Well shit, that barely counts at all. I graze the sun, like, five times before breakfast.

That is badass. I don't know which metal song that should be the video for...but there is one.

Where's the kaboom? There was supposed to be a sun-shattering kaboom!

Oh!
You mean that wasn't just a metaphor for Craig James?

I am torn between 1) joy that Lovejoy has survived its sun-grazing (seriously, check the video of its reappearance on the other side of the sun for the awesomest underdog moment of this lunar cycle), 2) terror that our best scientists' predictions about objects flinging around our solar system are often inaccurate, and 3) joy again at learning there's actually a whole class of things called Kreutz Sungrazers:
The Kreutz Sungrazers are a family of sungrazing comets, characterized by orbits taking them extremely close to the Sun at perihelion. They are believed to be fragments of one large comet that broke up several centuries ago and are named for German astronomer Heinrich Kreutz, who first demonstrated that they were related.
AwesomeAwesomeAwesomeAwesomeAwesome.
So, joy wins.

In other news, Icarus is suiting up to have another go.

The spacecraft I work on, PROBA2, also managed to observe the comet. Here's our video. Best watched at 720p and full-screen.
People here are very excited about all the wiggles in the tail, which are revealing some kind of interaction -- turbulence? magnetic activity? we don't know yet -- that I don't think anybody has really observed before.
(The images have been highly enhanced to bring the comet, which is very dim, out of the bright solar corona, which is why they may look a little strange if you're used to "normal" SDO or SOHO images of the sun.)
