Explanation: What do you think this is? Here’s a clue: it's bigger than a bread box. Much bigger. The answer is that pictured NGC 4753 is a twisted disk galaxy, where unusual dark dust filaments provide clues about its history. No one is sure what happened, but a leading model holds that a relatively normal disk galaxy gravitationally ripped apart a dusty satellite galaxy while its precession distorted the plane of the accreted debris as it rotated. The cosmic collision is hypothesized to have started about a billion years ago. NGC 4753 is seen from the side, and possibly would look like a normal spiral galaxy from the top. The bright orange halo is composed of many older stars that might trace dark matter. The featured Hubble image was recently reprocessed to highlight ultraviolet and red-light emissions.

Yeah the Anglo Saxon and Viking ships are pretty similar. In fact Anglo Saxon and Viking cultures were pretty similar pre Christianity. The Vikings pretty much did to to the Anglo Saxons in Britain what the Anglo Saxons did to the Romano Britain’s.

They keep pushing dark matter into every place they can. Too bad they’ve never isolated it.

Great picture of the gauzy or reticulated veil of dark dust lanes surrounding NGC 4753's Galactic Core! (Brady's discription works too.) In the imagination it looks like:
A glowing galactic core caught in a giant fishing net!
Creamy Golden Butter draining in a collander!
Great picture today M.C.! Thanks!

It is surprising to me that any galaxy looks perfect.
Why? Galaxies are supposedly 200 million light years across. The light from the closest part of the galaxy would reach the earth 200 million years before the farthest part of that galaxy. I would expect a lot of movement in that 200 million years.
