Pisces A (Psc A) is a void dwarf galaxy located in the Local Void in the Pisces constellation, near Pisces B. It is 18.4 million light-years (5.64 megaparsecs) away from Earth, and was discovered by the WIYN Observatory. About 100 million years ago, the galaxy started moving out of the void and into the local filament zone and denser gaseous environment, triggering a brief starburst period.
