Intergalactic dust information

Intergalactic dust is cosmic dust in between galaxies in intergalactic space.^[1] Evidence for intergalactic dust has been suggested as early as 1949, and study of it grew throughout the late 20th century.^[1] There are large variations in the distribution of intergalactic dust.^[1] The dust may affect intergalactic distance measurements, such as to supernovae and quasars in other galaxies.^[2] Partially due to absorption and re-emission of visible light by the dust, observations of more distant astronomical objects have greater apparent magnitude when conducted in infrared.^[3]

Intergalactic dust can form intergalactic dust clouds, known since the 1960s to exist around some galaxies.^[1] By the 1980s, at least four intergalactic dust clouds had been discovered within several megaparsecs of the Milky Way galaxy,^[1] exemplified by the Okroy Cloud.^[1]
