The cloud's size was "linear projected" to be 460 kiloparsecs, or about 2 million light years across, because the illuminated gas cloud is near quasar UM 287, which is believed to be 10 billion light years away from earth. This requires the cloud to be 10 times more massive than predicted to be so luminous. This amounts to over exaggerated speculation seeing undiscernably unclear cosmic web filaments for the first time.
Quasars are point-like energy sources, similar to nearly perfect shaped spheroidal stars and globular clusters. Ancient globular clusters comprised of old stars were discovered to have hopped around several or more galaxies. Halton Arp said that quasars are ejected from their host galaxy. Dwarf spheroidal galaxies may be closely related to globular clusters. The structure's viewing alignment and jet orientation plays an important factor in what kind of cosmic structure that we see.
Magnetic fields stabilize filaments. These filaments are easy to see in NGC 1275. They are 200 light years wide, and extend up to 20,000 light years. They're not so easy to see and believe to exist in the huge gas cloud.
