    Do you mean the source that is on the lower left? Sorry, no, that is probably another random source in the field of view - another star or galaxy. The sources in Disk Detective are all so far away, and the images we are using are so low spatial resolution, that we will never be able to see planets or even disks around these stars. We infer that there are disks around the stars because of the excess emission in the infrared that is what landed these objects in Disk Detective in the first place. But, sorry, no, we can't find disks or planets or moons in these images. (This is a very common question - perhaps we should do a blog post on this...)

    I agree about the blog Dr Irebull . One that would describe the closeness depth (distance) to us that we will be working with. Too bad these are not 3D images and that are too far away to (put us on a touch) to confirm basis. That brings to mind the question: Are these plates from this last survey ; the previous survey or a mix of the two? Is this statement true: Our capability of seeing actual planetary structure within a system is limited to our own solar system due to the distance that are experienced or observed even within our own galaxy.

    These images were all taken at slightly different times--the optical images were taken over a range of times but typically in the early 1990's. 2MASS images were taken in the late 1990's to about 2001 or so, while WISE took its data around 2010. As to the question about seeing planetary structure, it's all a matter of resolution and what color of light you're looking at. More on that from @lrebull
