Galaxyless

It is conjectured that these five galaxyless sources are not very distant background objects, but are produced by some plasma effect in the subcore medium of the Hercules Cluster.

In mapping specific regions of the celestial sky, astronomers in the 1970s began to report that many galaxies and clusters appeared to be strung out along lengthy curved chains separated by vast galaxyless space called voids.

Even the Absence was visible: that thumb-sized smudge of starless, galaxyless darkness in the direction where the Andromeda used to lie.
