Now on ScienceBlogs: Oldest Human-Made Object in Space
Speculations on astronomy, astrophysics, news I find interesting, theoretical issues, science and science policy. I will digress into computational physics, science fiction and general issues and basically whatever I feel like whenever. And, of course, cats.
Still working on an analytic exact approximate solution to the herding problem.
So you want to be an astrophysicist?
Random info.

NASA's SDO destroys a Sundog on launch.
Cool video.
The Solar Dynamics Observatory was launched, successfully, Feb 11th.
On the way up, the rocket crossed a high altitude layer of ice crystals - a wispy cloud - which was showing a Sundog - the rocket visibly rippled the cloud as it passed through - looks very cool.
Full launch video - ripples at ~ 1:50+

Glint to the right of the rocket trajectory as it crosses the cloud - "SDO video link" short video shows it slightly better.

And some say there's no evidence that human activity has atmospheric effects!
Seriously, that's so rare, what are the odds of it happening on a solar mission? Hmmm. Sounds portentous.
