Intergalactic dust
From Wikipedia, the free encyclopedia
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 supernova and quasars in other galaxies.[2]
Intergalactic dust can be a part of intergalactic dust clouds, shown to exist around some other galaxies since the 1960s.[1] By the 1980s, at least four intergalactic dust clouds were discovered within several megaparsec (Mpc) of the Milky Way galaxy,[1] and an example of this is the Okroy cloud.[1]
