Galaxy Group in Perseus

View larger images

This large and dense group is one of the most distant galaxy clusters that can be seen through amateur telescopes. The large bright galaxy to the left of center is NGC 1275, also known as Perseus A. It is a Seyfert galaxy and a strong emitter of radio waves. The blue and red streamers extending from this galaxy give some indication of the violent energy being emitted. Numerous other galaxies, spiral, elliptical, and irregular, are scattered throughout the field. Clicking on the larger images makes it easier to see the shapes of the many smaller galaxies. This field of view includes only the central section of this large galaxy cluster.
