This Hubble image shows ghostly green filaments, lying within galaxy 2MASX J22014163+1151237. This filament was illuminated by a blast of radiation from a quasar - a very luminous and compact region that surrounds the supermassive black hole at the center of its host galaxy. Its bright green hue is a result of ionized oxygen, which glows brightly at green wavelengths. Image credit: NASA / ESA / W. Keel, University of Alabama.

The Planck all-sky map at submillimeter wavelengths; the band running through the middle corresponds to dust in the Milky Way Galaxy; the black dots indicate the location of the proto-cluster candidates identified by Planck and subsequently observed by Herschel. The inset images showcase some of the observations made by Herschel’s SPIRE instrument; the contours represent the density of galaxies. Image credit: ESA / Planck Collaboration / H. Dole / D.
