[L2004] n 628-1743, cluster of stars.

  I noticed that this cluster of stars (according to SIMBAD) emits a lot of infrared and outshines everything else in this picture. What can cause that kind of thing?

  Never thought WISE would catch these.

  there is a lot of data of M74 on the net:
  Its spiral arms are about 1000 light years broad. They are traced with clusters of blue young stars and pinkish colored diffuse gaseous nebulae (H II regions). The large number of H II regions and the pronounced spiral pattern indicate that star formation currently occurs vividly in M74's disk. These regions show up as bright knots in the UV part of the spectrum also; see the images from the UIT telescope, ASTRO-1 Shuttle mission.
