It is located in the Local Void, near Pisces B; and is in the Pisces constellation. It is 18.4 million light-years (5.64 megaparsecs) away from Earth.[2] The galaxy was discovered with 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. This sparked off a doubling of the rate of star formation.[3] References1. ^1 2 3 4 {{cite simbad |title=[SCB2015] GALFA-Dw1 |accessdate= 21 February 2018 }} 2. ^1 2 3 4 {{cite journal |doi= 10.3847/0004-637X/827/2/89 |bibcode= 2016ApJ...827...89T |arxiv= 1607.03487 |title= Hstimaging of the Local Volume Dwarf Galaxies Pisces A and B: Prototypes for Local Group Dwarfs |journal= The Astrophysical Journal |volume= 827 |issue= 2 |pages= 89 |year= 2016 |last1= Tollerud |first1= Erik J |last2= Geha |first2= Marla C |last3= Grcevich |first3= Jana |last4= Putman |first4= Mary E |last5= Weisz |first5= Daniel R |last6= Dolphin |first6= Andrew E }} 3. ^ {{cite news |url= https://www.sciencedaily.com/releases/2016/08/160811142637.htm |title= Hubble uncovers a galaxy pair coming in from the wilderness |date= 11 August 2016 |publisher= Science Daily }} Further reading
