Astronomers surprised again, this time by alignment of planetary nebula.

"A recent study of PNs near our galaxy’s core showed their axes aligned with the galactic plane. “The alignment we’re seeing for these bipolar nebulae indicates something bizarre about star systems within the central bulge,” explains [Bryan] Rees. “For them to line up in the way we see, the star systems that formed these nebulae would have to be rotating perpendicular to the interstellar clouds from which they formed, which is very strange.”
Albert Zijlstra, the second author of the paper reporting the finding, echoes the surprise: “While any alignment at all is a surprise, to have it in the crowded central region of the galaxy is even more unexpected.”
“Surprise,” of course, is a euphemism for “falsification of theory.”"

It would be comical if it wasn't so wasteful.
