Please help me! Whatwe can see on this image

What you see is a compact #double in the radio with a very! messy infrared field. There looks like there's an object near the radio, and if you click on SDSS link, it's higher resolution, but so faint that not clear what we're looking at. So you were right to be confused by this one!

Woo hoo, there is plenty going on here! In tha radio image you can see a radio galaxy (contours in the middle) which we call in RGZ an #hourglass (it does look like it doesn't it?) This radio galaxy is composed of two radio lobes which are created by two very powerful jets ejected form the vicinity of a supermassive black hole. This comes from a faint but not far away galaxy, it's around redshift z=0.1
Now there is also a small radio blob in the left bottom corner. Thiis radio blob comes from a spiral galaxy that is only at a redshift z~0.07 - it's quite close-by.
You can see the spiral galaxy in this image: http://skyserver.sdss3.org/public/en/tools/chart/navi.aspx?ra=129.765375&dec=4.580638888888888&scale=0.2
The radio galaxy host is faint and is marked in that image, but it's not that well visible in optical wavelengths (the link above).Now, if we look at the infrared image beside, we can see three very bright sources. The small radio blob and the large infarared image (the spiral galaxy) are a match - it's the same source. But the other two very bright infrared sources are just very bright #stars which you can see in the above link as the two white-pink objects. They are not connected to our two radio sources at all. The match for out hourglass radio galaxy is an infrared source that look s like a blob coming from the star in the middle - this effect is just a coincidental superposition so the radio galaxy host and the star are blended.
Does it make sense? 😃
