One or separate objects?
It seems that these radio emissions are connected. All of them in radio freequency are located on one clear line. But are they from one source?
Welcome to Radio Galaxy Zoo, astronomas! 😃
With the possible exception of the faint (single contour) source to the SW ('below' the others)*, yes, they are all connected.
This is an example of a #triple, which is radio emission from a 'core' - host galaxy, containing the supermassive black hole and its accretion disk - and two 'lobes. The host is a quasar (or QSO), named SDSS J110153.45+624150.5; it has a redshift of 0.664. Here's the SDSS image of it (it's the blue star-like thing in the center):
There are several Galaxy Zoo blog posts which explain what's going on in more detail; perhaps The Curious Lives Of Radio Galaxies – Part One and The Curious Lives of Radio Galaxies – Part Two might be good ones to start with.
Hope this helps, and happy hunting!
*that may be an artifact, a bit like the 'compass points' spikes you see in optical images of stars; the tiny spot near the top is almost certainly an artifact
