Sombrero Galaxy Has Split Personality

ScienceDaily (Apr. 24, 2012) — While some galaxies are rotund and others are slender disks like our spiral Milky Way, new observations from NASA’s Spitzer Space Telescope show that the Sombrero galaxy is both. The galaxy, which is a round elliptical galaxy with a thin disk embedded inside, is one of the first known to exhibit characteristics of the two different types. The findings will lead to a better understanding of galaxy evolution, a topic still poorly understood.

“The Sombrero is more complex than previously thought,” said Dimitri Gadotti of the European Southern Observatory in Chile and lead author of a new paper on the findings appearing in the Monthly Notices of the Royal Astronomical Society. “The only way to understand all we know about this galaxy is to think of it as two galaxies, one inside the other.”

Two thoughts immediately spring to mind.  Do Galaxies have personality?  Perhaps they are sentient.  What would they think of us?

And secondly, if they are sentient, this galaxy is like two, one inside the other – is it pregnant?  Or giving a friend a hug?
