“The bar is made of relatively old and red stars, the survey shows. It is about 27,000 light-years long, or roughly 7,000 light-years longer than previously thought. Churchwell's team also found that the bar is oriented at about a 45-degree angle relative to the main plane of the galaxy, in which the Sun and the other spiral-arm stars orbit.

I was wondering how the S orbit which rotates around 3 axes and can only happen for points along a straight line at 45* from center to edge of the disc fits in with a disc of curving arms rotating around only 2 axes- it doesn’t. It remains a straight line and sometimes sticks out 45* from the plane of the galactic disc.

The bar's not in the plane...
so, they're not serving drinks on the flight? (*Rimshot*)

The Stars in the Bars are nowhere near Ours...

I guess the stars wanted to avoid collisions. They're really sensitive about that.

"One of the hallmarks of life is its ability to adjust its behavior in response to stimulus. Matloff began searching for astronomical objects that unexpectedly exhibit this behavior. Recently, he zeroed in on a little-studied anomaly in stellar motion known as Paranego’s Discontinuity."
[...]
"Matloff noted further that some stars appear to emit jets that point in only one direction, an unbalanced process that could cause a star to alter its motion. He wondered: Could this actually be a willful process? Is there any way to tell?"
