What's the blue bit?

by jedkat

I can't find any indication of it on sky server, but it doesn't look like an artifact or star.

in fact, if you look at the skyserver image there is nothing where the blue blob should be.

any help would be great!

The blue thingy could be a foreground star. This is an infrared image and the artifacts are very special ! 😄

There's not star when you look at the image in SkyServer. In fact, there is absolutely nothing where the blue blob should be.

Then it is an artifact. With these infrared images we get lots of new artifacts!

Could the blue object be another Voorwerp?
