devoid of any stars. It is associated with the asymmetric spiral galaxy NGC 2442. It is likely that HIPASS J0731-69 was torn loose from NGC 2442 by a companion. HIPASS J1712-64 HIPASS J1712-64 is an isolated extragalactic cloud of neutral hydrogen with no associated stars. The cloud is a binary system and is not dense enough to form stars. HIPASS J1712-64 was probably ejected during an interaction between the Magellanic clouds and the Milky way.
