More news from the IAU meeting: for the first time, astronomers have found direct -- and to my eye, fairly convincing -- evidence of dark matter. Indirect evidence is all over the place, but no direct evidence, until now, has been found.
Now I was gonna write all this stuff about the history of dark matter, and how they made these observations, and why this is not only terribly important, but also very, very cool-- but then I found that those folks at Cosmic Variance already did. So my work here is done.
