The light from one such galaxy, named SPT0615-JD, began its journey toward Earth 13.3 billion years ago. (scientificamerican.com)

Because of this extreme distance, the infrared light from dust grains heated by starlight is redshifted into longer wavelengths, and the dusty galaxies are therefore best observed in submillimetre wavelengths of light. (eso.org)

The developing cluster presumably will grow into a massive galactic city, similar in size to the nearby Virgo Cluster, a collection of more than 2000 galaxies. (esa.int)
The image also reveals many other galaxies forming the Virgo Cluster, of which M87 is the largest member. (astronomy.com)
