Hmmmm. It's actually very plain to see and I wonder if you ever taken a colour blindness test Sam? Take a look at THIS one. ![Don't know :dunno:](http://www.pc-pals.com/smf/Smileys/Smileys/dunno2.gif)
lol. That;s a nice test... and I can see all that! So I ain't colourblind - I just have a stupidity filter on.
I've asked a bunch of other astronomers and none of them can see it... just looks like noise to us.

Maybe we are just used to looking at poor quality data (though this data is pretty fantastic, but looking at the noise etc).... and going there is nothing there
