Backward spinning Galaxy

Back in February Nasa announced that Hubble had identified a ‘backwards’ spinning galaxy. Nasa claims that is is spinning clockwise. A few questions here.

Why is it so odd ?
Couldn’t we just be looking at it from the wrong perspective? (depending on your vantage point it MAY be spinning anti-clockwise)

Before you even ask… you can check it out here

They pretty much answered those questions on their site.

It’s anti-matter.
Yeah, that’s the ticket.

It’s not so much that the galaxy appears to be spinning clockwise, it’s that the galaxy’s “arms” are moving foreward, instead of trailing behind the rotation as all other spiral galaxies appear to do.

Actually, only SOME of the spiral arms are pointing in the wrong directions. Others are lagging behind the direction of spin as you’d expect. Look here where you can see much finer details.

AHunter3, what exactly am I supposed to be picking out in that image? :confused:

Look in the upper left 1/4 of the picture and you can see some smaller arms forming that are trailing behind a clockwise rotation (and therefore bridging the gaps between the more imposing arms). I’m no physicist, but I’d imagine that we’re actually looking at two galaxies merging / superimposed on each other, “vertically” from our perspective, spinning in opposite directions, one with considerably more prominent spiral arms than the other, and that they are starting to disrupt each other as they merge.

Oh. OK.

I hate space. :frowning:

Why? What’s the matter?

Long story. Not relevant to here. Sorry.

There is more detailed information here and the links within, especially this one.
