Green object is just starforming area?

Do you mean this object?
Not sure.
Area looks as if it could be a burnt-out voorwerp. I think I can see an arm of the galaxy going into the area. So in the past, the relativistic jet of the quasar could have hit the arm and initiated star formation. I'll alert a scientist.

Yes exactly that area. But i'm sceptic of this so I asked.
It looks very green instead of voorwerp blue, might be the complete SDSS area is suffering from that. Same holds for starforming areas. (Milky Way gas / dust extinction effect?)
But also there seem to be smaller but similar areas on the other spiral arm on roughly same position, so might be 'greenified' starforming areas, very difficult to judge.
'Burnt-out' voorwerp is official 😃 ? any examples to compare with besides regular voorwerpjes?
PS: galaxy is 'radio-active'.

In the zoomed out view one can see lots of other objects with the same colour as the green object. All the objects appear where one would usually expect to see starforming areas in a galaxy.
The whole galaxy is red. Could that has made the blue colour of starformation turn into yellow-green?

Well it is a Zone Of Avoidance Galaxy so looking true all the gas and dust from the Milky Way, might affect colours strongly.
